As a little project, I took the link provided by the other Rob and make this little search tool. It only looks at the beginning numbers. It does no number validation. I don't validate the length of the number. ie: I would have to know the min/max lenth of each phone number for that given country/region, and I didn't search for that information. You can't check for length, that depends on each national administration and while some countries have all phone numbers exactly the same length, some other countries do it the old style: small phone exchanges have few digits, larger have more, which gets compensated by the smaller exchanges having longer area codes. The idea is that within small towns, you dial short numbers to reach your neighbour and, if someone dials from outside the area, they have to dial a longer area code prefix, but since the town is small, there is a lesser chance that many people will have any business dialing them anyway so, overall, you get to dial less. Also, in electromechanical phone exchanges, each extra digit (actually couple of digits) requires an extra row of 'selectors', which are (were) expensive. This still happens at the country level, not because it really matters nowadays but due to the existing technology when it was agreed on it. Large countries in Latin America have two digit country codes (political maneuvering at the time of assignment distorted this somewhat, letting Peru and Cuba get 2 digits which don't fit their actual number of phone lines). Thus, from 51 to 58 they are assigned to the larger countries. The 59x and 50x ranges (in phone numbering the zero is after the nine within the same decade) go to countries with less phone lines.

Re: [PHP] Get country from Phone number
It is not as bad as it looks. The only important columns are the first two, the last two are how you dial from within the country to place long distance international or national calls. In many countries, when there are several low cost international call providers, they use different prefixes, actually, it is quite absurd that they list all options for low cost carriers for, say, Venezuela, while they don't for the USA where there are as many or more. The only tough part is that several countries, share the +1 prefix, the USA and Canada are the larger, but many Caribean countries, which originally got their service through the US phone system, are also mixed in. So, in those cases, you have to check through the 'area codes'. A similar thing happens with the ex-Soviet republics, they all share the 7 prefix. As for the rest, it is quite straighforward. 1 is North America 2 is Africa 3 and 4 Europe 5 rest of the Americas 6 Oceania 7 Russia and ex-soviet republics 8 FarEast 9 rest of Asia Most prefixes are of varying lenghts. The countries with the most phone lines get the shorter prefixes so the overall number is more or less the same for all. Thus, Mexico and Brazil get two digit codes in the 5 range while smaller Nicaragua gets three.

Re: [PHP] global address collection
Actually, phone numbers should not be prefixed with 00. The prefix for international dialing depends on the local phone regulations and it is different in different countries (for example, 011 in the USA). The recommendation from the telephone union (http://www.itu.int/) is to use a plus sign to indicate that the phone number starts with the country prefix. Thus, it would be: +44 1623 123456 or +1 408 555 1212. Americans also get often confused because the first 1 is both the country code for the US, Canada and a good chunk of the Caribbean and it is, at the same time, the prefix they use to dial national long distance. That's why the + is important. In most of the world, the leading zeros are like ../. You can thing of local phone numbers as your current directory. If you want to dial another area code, you first dial a zero, which is like using ../ in a file system, and then the area code, like the folder for that local number folder. If you want to dial international, you dial 00, which is like doing ../../, which gets you to the world root (eventually there might be three zeros to dial interplanetary!) and then dial the 'folder name' of the other country. Which reminds me of an observation by Arthur C Clarke that once humankind becomes an intergalactic civilization each group will lose communication with the rest, can you just imagine what phone numbers might be! (Brits always had a peculiar sense of humor) There is no mandatory format to separate international dialing prefix, country code, area code and actual number, it is better to have them separated at least with a blank space, but there is no standard regarding that and none should automatically impossed, the spacing provided by the user should be respected. Once again Americans are use to see their numbers as 1-408-555-1212 because all their area codes are 3 digits long and all the local numbers contain 7 digits grouped as 3 and 4, but most countries use a variable number of digits for area codes so only the person who entered the number can know how to split it. Do not delete the whitespace and then reformat the numbers assuming a fixed format because none actually exists. Tables of international dialing codes are available just googling around (for example, http://www.kropla.com/dialcode.htm), it is not a bad idea to check country against the first part of the phone number but then, a warning is all you could possibly issue since a person might have a postal address in, say, Monaco (+377) and a French mobile (+33). I wouldn't imagine that the Vatican has a separate mobile network from that of Rome so though they have an international prefix different from that of Italy which they might use for their land lines, their mobiles are probably Italian. Also, it should be Province/County/State, and it should be optional since some cities are autonomous (usuall federal capital cities), just don't make it mandatory. And don't force anything on postal codes. Some countries have letters in them and the number of characters varies. I just hate it when they ask to enter the full 9 digit zip code.

Re: [PHP] Looking for ways to prevent timeout
- Original Message - From: Jochem Maas [EMAIL PROTECTED] Dan Brown (the nice guy on this list, not the twat that wrote the 'daVinci Code') suggests a *much* better way to go- namely using a CLI script. the fun part is getting a button push on an admin page to somehow initiate the CLI script. one way of doing this could be to have a 'job' table in your database to which 'jobs' are inserted (e.g. 'do my 3 record import') and that your [CLI] script checks the database to see if it should start a 'job' and just exit if it does not need to do so ... lastly in order to have the [CLI] script regularly check if it needs to do something you can use cron to schedule that the script runs at regular intervals (e.g. every 15 minutes) many ways to skin this cat - my guess is all the decent ways of doing it will involve a CLI script probably in conjunction with a cronjob. if you arent familiar w/ ajax, no worries; the main concept in my suggestion is sending a number of requests rather than a single request. that way you can execute a fraction of the queries on each request. this will ensure that you dont hit the maximum execution time. Just to comment an alternative on how to break the job. It is just something that happened to me once and might be useful. My particular job could be naturally broken in several stages. Actually, it had to. Though it could be solved with a huge complex SQL query with several joins and subqueries (which were not available), it could also be perfomed with the help of a few intermediate auxiliary tables. So I had a query (which would have been the sub-query) inserting records into a flat table with no indexes. On a second step I added the index, then there was another join in between this auxiliary table and another table (and this one was pretty complex and at that time, with no stored procedures, it required some processing with PHP) and the final step that produced the result. At that time, before AJAX was popular, I showed the progress on an iframe on which I changed the src attribute for each successive step (poor man's AJAX), but it could also be done via AJAX or reloading the whole page instead of an iframe within it. Some time later I tried to redo one other such process into a single query with subqueries and I found that using the auxiliary tables was faster. I admit that my attempt was half-hearted, I wanted to either see a big improvement or ignore the whole business. The improvement wasn't that big so I dropped it and assumed the other processes would not show any big improvement either. After all, I knew the data and optimized it as much as possible so I can't assume the SQL optimizer could do much better than I had.

Re: [PHP] Using PHP to determine if user has Java installed
I would think that if you put an applet in the page with some public property or method which you could then query from JavaScript if it succeeds it means you do have Java, not only installed but available and enabled to the browser, then you could either send a AJAX message to the server or navigate to some other page. The client might still have Java but not enabled for the browser though and this test would fail. The Java applet itself might communicate to the server but then you wouldn't be able to do much with that page as I don't believe an applet has that much control over the page it resides in. - Original Message - From: Matt Livingston [EMAIL PROTECTED] To: php-general@lists.php.net Sent: Wednesday, September 05, 2007 11:17 PM Subject: [PHP] Using PHP to determine if user has Java installed Hey List, I want to know if it is possible to use PHP to find out if a visitor has Java Runtime Environment installed on a computer.

Re: [PHP] need insights on encrypting and uploading ASCII file using PHP
There are two different things you might want, ensure that the data is not seen by eavesdroppers while in transit or ascertain that the data comes from who says it is. The first, you manage with SSL as with any other secure transaction, as already sugested. For the second is what you might want to use a digital signature, that's why someone might have sugested it to you. As a sample of how this would work you read the file into memory, add a long string, the signature, that is never transmitted but that both ends know, and pass it all through an algorithm like MD5 or such. At the receiving end, you get the data and the MD5 but, as I said, the signature is never transmitted, but you know it as well. You do the same process as in the sending end and you should reach the same MD5. Since MD5 is not reversible, knowing the MD5 of this long string, the data plus the signature, cannot reveal the signature even if the data is transmitted in clear text, but no other except someone who has the signature can produce the right MD5. Notice that the data itself is transmitted in clear text, the goal is to ensure that who sends it is who is meant. A similar process has been in use in the banking industry for wire transfers when they were really sent via telex. As mentioned PGP is a far better solution since it covers both requirements and it uses two keys, one for encoding and one for decoding so that each end knows just half of the information and won't require you to use SSL, the problem is that you have to do some processing at the client side and JavaScript alone won't allow you to access the file system. You would have to deploy ActiveX controls or Konfabulator widgets (plust the widget runtime). On the other hand, many eMail clients can send PGP protected messages. Finally, you could get your users to ZIP the files with a password before sending them, which is not so secure but is good enough for many uses. IT all depends on what you want.

Re: [PHP] Authentication
If memory doesn't fail me, if you work with IIS and protect the source pages of the application so that IUSR_x (the generic anonymous user) doesn't have access to those files and instead grant access to the NT users or groups which you want, the IIS when working with IE clients will take care of that as long as they are all in the same domain.

Re: [PHP] No is_date() function?
There is no such a thing as a date datatype in PHP. Dates are stored as an
integer representing seconds since a base time (1/1/1970) and they cannot be
distinguished from other integers. In PHP 5.1 they added a DateTime class
which is a good thing for the future, to solve issues like yours, but for
the time being, a 'timestamp' as returned by, for example' mktime, is a
plain integer.

Subject: [PHP] No is_date() function?
Hi
I wrote a serialization function to turn arbitrary PHP variables into
Macintosh plist compatible XML but see that there is no is_date tester
as there is for bool, object, array etc. Is there a relatively simple
(and robust) way to detect if a variable is a date? For example:
$person = array('name'='bob', 'sex'='male', 'date_of_birth'=
$someDateHere);
Thanks for any help

Re: [PHP] Displaying HTML characters in real format
Unless you have set the character encoding of the document to the same as what you have, say, in the database, you would have trouble showing, for example, your last name, with that umlaut.

Re: [PHP] OK to have many files in one folder?
Since it depends on many factors, some out of your control, some others that might vary over the lifetime of the application, one thing you might do, to be on the safe side is try to put files in different directories, for example, by breaking up their filenames every three characters and making each segment a folder but no more than three levels deep so that the file ./abcdefghijkl.jpg would be located at ./abc/def/ghijkl.jpg. This breakup would allow even to mount extra disk volumes for some of the folders, should they exceed certain capacity or to split the risk. Whether to break filenames every two, three or more characters might be a matter of optimization, but I would guess that around three (or four) for the first two segments and whatever is left for the filename would be a reasonable number. I wouldn't go more than three levels deep either, because jumping from one directory level to the next also takes some time, thus it is a compromise in between searching sequentially in a directory for a filename (for those filesystems that do so) and going deep into the directory tree.

Re: [PHP] MySQL Connection in Session ?
In most systems, database connections are pooled, meaning that when you give them up, they are not completely closed but the sql client software keeps them in a pool available for the next script asking for a similar connection, thus saving on the time to establish a connection.It is the connection between your script and the sql client that gets cut, the database does not know your script is gone, since the sql client doesn't tell it. For the pooling to work, it is necesary that all the connections requested have the same parameters, including user name and password. If you change username for each page, then the client software has to actually establish a connection for that user to retrieve the proper permisions. Of course, that connection would also be sent to the pool once the page is processed, but then the pool would soon fill up with many connections, one per username, each seldom used and in a really busy server, the connection would be dropped out of the pool before it gets a chance to be reused. Storing those many connection in session variables only moves the problem from having the sql client manage a large pool of little used connections to have PHP sessions do the same thing, far more inneficiently. The best thing is to make sure all connections you use are opened with exactly the same parameters, use just one connection for all the script (unless, of course, you actually have to connect to different databases) and let it go as fast as you can to give the next in line a chance to reuse it from the pool.

Re: [PHP] RE: Return or not to return, that is the question
- Original Message - From: Richard Davey [EMAIL PROTECTED] That is all my original thread was ever really asking - I was just curious what other people thought about returning from functions that don't actually require a return value. So far the responses have been pretty varied, from the (somewhat blinkered) 'how can a function never return something?', to 'yes I always return' to 'no I just let it run out'. My rule is to write what you mean, and if you don't mean to return anything valid or worth anything, just don't. If you explicitly put a return it should be for a reason, whatever you return should be meaningful. If I find a 'return true' at the end of a piece of code, I will check if there is any condition where it returns false, because I will assume that the return true is significant and so should be its obvious alternative. I would also wonder why the caller doesn't use that return value or if it does, why is there no 'else' part. In a similar line, I use 'null' in databases when I mean 'I have no valid information for this field'. Basically, the idea is to be clear in what you mean. If you put a return it should be because you mean to return something. If you mean you don't know, use 'null', don't default to zero or any other implausible value for that field. This kind of arbitrary conventions dilute the self-documenting value of well-written code, quite the opposite, they would need to be documented themselves to avoid missinterpretations.

Subject: [PHP] ${}
where can I find the documentation about this symbol?
It is one of those almost hidden treasures that is documented, a little bit
here and there, but it doesn't have a page on its own.
It is used to dissambiguate complex variables, specially when embedded
within double-quoted strings, so the interpreter knows how far does the
variable name and its parts go and when the rest of the string goes. For
example, if withing a double-quoted or heredoc string, the variable name is
immediately followed by a text or number without any spaces in between, the
interpreted can't know whether those characters are part of the variable
name or not. Also, when you want to refer to an array element or an object
property, the resulting expression might get somewhat more complicated and
there might be ambiguities as to how far does the variable goes and where
the rest of the string goes.
It might also be used to generate variable names on the fly, ${'variable' .
$i} will produce the contents of $variable0 for $i = 0.
I think it was also used to refer to individual characters within a string
as if it was a character array, but that is deprecated in favour of square
brackets.

Re: [PHP] free allocated memory: HOW ?
When you free memory you are only marking memory as available for reclaiming, but it doesn't mean it will actually reclaim it at all. The garbage collector usually runs at a very low priority and if you don't give your process a break, it will never catch up. One thing I would try is to insert a call to sleep() within the loop and see if that gets the garbage collector to do some catching up (and if it does, please let us know). Another thing would be to have a master process shelling out processes to process a template one at a time. It might either be either through exec() or using curl to request Apache to deal with handling the processes. The end of each individual process would free all its memory and, after all, that is the way PHP is meant to run and has been highly optimized to do. Using some shared memory to communicate whatever needs to be shared would avoid too much repetition. If the templates to be processed are large, perhaps you can get some external utility to process it far more efficiently. Nevertheless, I wouldn't try any of that until I exahusted all that can be done on the programming side. Are you using file_get_contents to read whole chunks at a time? Is it really necesary? Can you manage to read a line at a time? If having the whole template in memory is required, can you break it up into an array with explode() and operate on each line at a time or whatever unit you have? Or better yeat, have it read a line at a time into an array and avoid the explode(). Memory gets a better chance of being reused if it is split into many smaller chunks. Using square brackets to access and specially modify individual characters as if the string is an array of characters works on the string right in place, avoiding copying and trashing the memory, though it might not be faster. Anyway, these are no more than random thoughts and nothing beats a good application design, something that nowadays, with so much memory and powerful processors tends to be overlooked.

Okay, so I should set the default time zone to central GMT time, and then save GMT offset for every user. This sounds realistic, because I don't think that I need to correct the time for users that doesn't login. Well, that was my whole point. If you store the GMT offsets for each user at a certain time in the year, they will turn invalid when they switch from daylight savings to no savings. Not all countries use daylight savings and even those that do don't switch at the same time. Furthermore, northern and southern hemispheres switch in opposite directions, if and when they do. If your users have to log in, that is the perfect time to read their current local time from the browser and keep it just for the session. Don't store it permanently. In PHP dates are stored as seconds from an arbitrary zero set at Jan 1st, 1970, so does MySql with date/time values though it shows them formatted but you can use the UNIX_TIMESTAMP function to get the actual timestamp. JavaScript uses milliseconds from the same base date. The rest is plain arithmetic. Satyam So, if I now have the GMT offset for every user, how do I display the right date?

Re: [PHP] Sense last record
I would use some JavaScript on the client side to go through the table and
change the classes once the whole page is loaded.
Otherwise, for a pure PHP solution, I might either load the whole table on
an array, which is wasteful in memory, or defer the actual output of each
record until the next record is read so, if no further records exist, I
would change the class name of the row still in a variable and output the
row right after the loop ends before the end of the table.

Re: [PHP] mysql if empty
An empty result is still a valid result. As long as the SQL statement is
valid, you will get a result set. This doesn't meant that the variable
holding the reference to the result set is itself empty, but that you will
fail to fetch any results from it.

But words like and are really english i think :) Keep in mind that this is quite a hard way i think, but i don't have a better solution. Just for example, Dutch and Afrikaans are not very different, so it's really hard to see which of the 2 the text is written in. Tijnema ps. If you can't get the difference between Dutch and Afrikaans, guess for Dutch :) It's a lot more used then Afrikaans. yeah, looking for very frequently used words seems better idea. greets Zoltán Németh In Spanish, as it happens with many languages that use diacritical marks, in informal chatting you often skip them. This has a long tradition in the internet since years ago the support for those extra characters was non-existent and today it is still somewhat patchy. I used to have two modes of writing in Spanish, formal writing with all proper accents, tilde and umlauts and email mode, without any of those. Nowadays, with support for languages using the Roman alphabet widely available, there is no need to omit diacritical marks, but you will often find them missing, particularly in comments to blogs and other informal writing, just because of laziness or carelessness or simply lack of formal education and in that I include foreigners who more or less handle the language but not the minor details. If English had accents, I would probably skip them. So, using a spelling dictionary is not a good idea unless you can count your input to be properly written. A text in Spanish with its accents missing will give you lots of errors, and we use just one sort of accent (acute) plus tilde and umlaut. The French use three sorts of accents, there is a far higher chance of getting misspellings. I don't know how abundant accents are in Magyar, for me Zoltan Nemeth is the same as Zoltán Németh, but the first is a misspelling. This problem also affect the frequency of individual letters. Should you first convert accented vowels to their plain version? Because if you find accented letters, it is a sure sign that it is not English, but if there is none, it doesn't mean it is English, it might be some non-English text without the correct accents. Should you count 'a' and 'á' separate or add them together because people often omit the accent? So, I also vote for the frequently used words approach and against the lowest number of misspellings. And I would first convert everything to plain, with no accents, both for the needle and the haystack. Satyam PS: also, it is accepted practice to omit accents on uppercase letters such as in headings. It is not gramatically correct but a typographical convention which the printing industry has been using for ages: the accents simply don't fit nicely. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Timezone offset
Since about the US and most of the world that still do daylight savings started doing so, which was bout WWII. Most of Europe does, we changed this past weekend. We don't match the US in the dates, but we do it. In the Southern Hemisphere they do it the opposite way, since summer and winter come in opposite months of the calendar, so time differences with countries in different hemispheres (north south) might move about 2 hours along the year.

4. And then to retrieve this value on my next page just get it out of

basically yes
but if you want the id of the row you just inserted, using
mysql_insert_id() is better because if another insert is happening at

Re: [PHP] Add New Records Only!
Delete from table where id = (select min(id) from table group by field1,
field2 ,... having count(id) 1)
Id is the unique primary key, fieldn are the fields that can be duplicated.
Each time this runs it will remove one occurence of the all duplicated
records. You'd have to run it several times until it deletes no more
records. In MySql, you cannot have the same table in the 'delete' and in
the subquery, thus, you will have to first insert the id's in an auxiliary
table and then delete the records.

Three: Insert everything and remove duplicates later.
Ave,
Let me explain what I¹m trying to do. Unfortunately it¹s not a very
simple
Add/Update transaction.
Basically I gather records from multiple mySQL tables and add them to a
DBF
(dbase) database. I wrote a code which was able to accomplish this
without any problems and the add_records goes very smooth.
However, I have to modify this program now so that only ³New² records,
i.e., records that have not yet been transferred, are added into the
DBF.
In other words, any records that are being added, which already exist in
the DBF, should not be added.
If it were just adding records from one mySQL to another mySQL, I could
easily use INSERT IGNORE or the Unique Key fundamental however, since
I¹m adding from multiple mySQL tables into DBF, I¹m not sure how to go
about doing this.
Here¹s my code that takes records from multiple mySQL tables and adds
them
to a DBF.
// define the array with mySQL Table Names Identifier
$tChoice = array(
lodispo = VB,
lodispo_osma = ATL,
lodispo_osmh = HOU,
lodispo_osmn = NSV,
lodispo_osmp = PAA,
lodispo_osmj = JAX,
lodispo_osmt = TPA,
lodispo_dmam = MET,
lodispo_osmf = FTM,
lodispo_hfglend = GLEND,
lodispo_hfmesa = MESA,
lodispo_hfphenx = PHENX,
);
// open DBF in read-write mode
$db2 = dbase_open($theDBFfile, 2);
if (!$db2) {
echo BRBRSTRONGFatal Error:/STRONG Unable to open
databaseBRBR;
exit;
}
else {
// Let's Run Array Loops!
foreach ($tChoice as $tblQ = $bxQ) {
// connect to mySQL tables one by one
mysql_select_db($database_imslead_transfer,
$imslead_transfer); $query_loDispo = SELECT * FROM $tblQ;
$loDispo = mysql_query($query_loDispo, $imslead_transfer) or
die(mysql_error());
$row_loDispo = mysql_fetch_assoc($loDispo);
$totalRows_loDispo = mysql_num_rows($loDispo);
// write mySql data to Dbf
do {
dbase_add_record($db2, array(
$row_loDispo['phone'],
$row_loDispo['comments'],
$row_loDispo['starttime'],
$row_loDispo['endtime'],
$row_loDispo['dispo'],
$row_loDispo['loanofficer'],
$row_loDispo['verifier'],
$bxQ));
} while ($row_loDispo = mysql_fetch_assoc($loDispo));
}
dbase_close($db2);
}
Any suggestions would be highly appreciated.
Thanks,

Re: [PHP] POST a variable
It seems to me @@identity should sufice, and it certainly does not need to
be any 'new' function, since it had been there for quite a while. My
feeling is that those added functions might be used for elaborate stored
procedures, where you might be dealing with multiple tables or some fancy
administrative uses. You certainly DON'T want any function that gives you
the last identity of some other connection!
$get_max = SELECT @@identity;
$max_result = mssql_query($get_max) or die(mssql_error());
$max_id = mssql_fetch_row($max_result);
echo $max_id[0];
Though the fetch will return only one record with only one field, it will
still return that as an array, even if it only contains one element, so you
still need to add the [0]. Unfortunately, PHP doesn't allow the brackets to
a function that returns an array.
You might use mssql_result instead:
$get_max = SELECT @@identity;
$max_result = mssql_query($get_max) or die(mssql_error());
$max_id = mssql_result($max_result,0,0);
echo $max_id;

Sorry, I was more tailoring my question to the syntax of my query. It
wasn't displaying anything for my echo.
I've changed it to this now:
$get_max = SELECT scope_identity();
$max_result = mssql_query($get_max) or die(mssql_error());
$max_id = mssql_fetch_row($max_result);
echo $max_id;
But all my echo returns is array instead of the number.
Below are brief explanations of the different _identity uses you have.
SELECT *@@IDENTITY*
Returns the last IDENTITY value produced on a connection, regardless of the
table that produced the value, and regardless of the scope of the statement
that produced the value.
SELECT *IDENT_CURRENT(*'*tablename*'*)*
This new function returns the last IDENTITY value produced in a table,
regardless of the connection that created the value, and regardless of the
scope of the statement that produced the value.
SELECT *SCOPE_IDENTITY()*
This new function returns the last IDENTITY value produced on a connection
and by a statement in the same scope, regardless of the table that produced
the value.

nor have I dealt with one for the last few years, though I did use

that gives you the value, but it looks to me @@identity is the one you are
looking for.
There is no need in your code to do any while, if the SQL statement
doesn't fail and triggers the die(), you can rest assured you'll get a
record with a single field, even if it only contains a null, that's the
way
with variables, you can't fail on them, though they might return null.

Thanks. That is a bit different than what I was thinking about but it might work for my purposes. Thanks also to all the other people who made suggestions. It appears to me that ther are 3 distinct approaches. 1) Generate a random number. Query the DB to see if it has been used before and if so generate another random number and repeat. It seems to me that this would require that the DB be locked for the checking and insertion to make sure a duplicate was not slipped in. 2) Generate a random number. Make a trial insertion for a unique field. If the insertion fails repeat. This functions just like the above but uses Mysql's native behavior to handle the checking so no user locking is necessary. Almost all the time this will require only 1 insertion whereas the above will require 2 or more accesses. 3) Generate a unique identifier from the record sequence number. Since the sequence number is guaranteed to be unique the identifier will also be unique and can be used without any worry. There are various schemes I can think of by which the unique identifier, altho uniquely determined by the sequence number, can be generated so that it will not reveal the sequence number and appear unpredictable. This will require 3 accesses to the DB (insertion, mysql_insert_id, and update). I have a number of options to try and think about. Thanks again.

Re: [PHP] IP to City detection
It is very hard to get to the level of city. It is the way the networks are built. I live in a minor town. My provider has a node in this city, but it gathers all the traffic of the whole area (my town and neighboring towns) and sends it through an internal link to their major regional center. Depending on availability, my traffic might get to the Internet (uppercase Internet, the big, public, global one which links us all together) right through that regional node or, depending on traffic, it might get beamed over somewhere else and get into the Internet at another less busy node. Big providers are constantly shufling traffic around depending on the availabilty of their own internal network and that of their wholesale provider. The IP you see exposed to the Internet is that of the node where your provider internal network connects to the public network, the uppercase Internet. Due to national regulations, it is usually hard for one national provider to use IP addresses belonging to another country so, IP to country tables are quite reliable. IP to city is not reliable at all, there is not external rules imposing arbitrary borders on traffic so a provider is free to send packets wherever it becomes more efficient. Moreover, if a client has the same provider as your service, the IP address you receive might be an internal IP address and not an actual Interner address. Internal IP addresses have little restrictions, they can be almost anything. If that were the case, all bets are off. These days with the CeBit show running at Frankfurt, Deutsch Telekom (sorry about the spelling) might be struggling with their bandwith around that area. Data packets might be popping about everywhere in Germany and, if they have agreements with neighboring countries, some might be showing up at Denmark, Austria or Poland, who knows! My town is close to Barcelona, Spain. When they had the 3G mobile phone conference there last month, my packets might be going to Tarragona, Valencia or even all the way to Madrid. Comercial IP to location databases, at least, keep in close contact with the major providers so they have a close idea of how are they routing their packets. Non-comercial databases don't have the resoorces to keep updated. The only reason they are more or less reliable at the IP to country level is that governments have different regulations in each country and they know there is value in the information flowing through the optical fibers so, while they figure out how to tax those bits and bytes, they make it just a little more hard for them to flow from one country to the next, but within a single country, there are no limits.

The correct capitalization is José de la Rosa.

Most databases offer some sort of autoincrementing integer and a means to get its value immediately after an insert. The syntax both for creating it and retrieving it might vary, but it exists in some form or other.

Re: [PHP] PHP URL issues
There are lies, damned lies and statistics. Had he known about benchmarks! I have already tried different ways of producing output and I completely disagree that concatenating the pieces and then echoing them is the best. In a first try, I found that echoing the separate parts as arguments to echo with commas in between was the fastest and variable interpolation within double quotes strings (or heredoc) was fastest than concatenation. Nevertheless, in a later trial, the numbers which were so clearly in favor of echo with multiple arguments, turned only slightly better, not enough to justify the loss of flexibility of building up a string first and having the option of manipulating it. This last sentence was confusing, lets see. When writing functions, you might either have them do the echo themselves or returning a string. The first is fastest, the second offers flexibility. If the first is really much faster, I'm willing to do away with the flexibility, which is no more than a potencial benefit, since 90% of the time I might have nothing at all to do with the return value of the funcion and, if really needed, I might use output buffering. Neverhteless, if the straight echoes are not that much faster, I'd rather keep an ace in my sleeve and go with returning strings. In my first trial, the result was conclusive, it was about 4 to 1, in the second, it was about 20% faster. The first was done on my own personal machine, a Windows machine doing nothing else, the second on my ISP shared hosting with an unknown load. I might say that my test on my own idle machine was the most representative, since it didn't have to deal with external issues such as competing for external resources, but then, that competition is really part of life. Though avoiding the memory shuffling of doing many string concatenations, doing echoes with multiple arguments might require the interpreter to negotiate access to IO buffers more often than building the whole page in memory and then getting it echoed just once. And I am sure that the way Windows and Linux handles IO with Apache is quite different, so, which benchmark is really representative? I am sure that some benchmarks are quite representative, independent of platforms. For example, it would make sense that doing an exact equality (triple =) should be faster than a plain equality. The first fails straight away if types are different and in no case is any conversion made. In the second, if the types don't match conversions need to be made first (after figuring out which one to make) so logic indicates it should take longer. Nevertheless, I don't feel like testing it out since the results, as my previous experience indicate, seem to be so uncertain. I'm not even arguing whether it makes sense or not in trying to shave off a few ticks of the clock. I am sure that a machine handling who knows how many users requests simultaneously will appreciate any little help, actually, I'm not sure I am actually looking for answers because, as far as I know, the answer is: it depends Satyam - Original Message - From: Richard Lynch [EMAIL PROTECTED] To: Steve [EMAIL PROTECTED] Cc: php-general@lists.php.net Sent: Wednesday, March 14, 2007 10:07 AM Subject: Re: [PHP] PHP URL issues On Tue, March 13, 2007 9:31 am, Steve wrote: This may or may not help, but here's a few things to note: 1) I would avoid placing variable output in double quoted strings.

Fw: [PHP] PHP URL issues
One more example of a questionable benchmark, not wrong but I wonder (as I was doing in my previous) whether it is really representative. There are two main ways to handle strings, one is to malloc exactly the required memory for each string and keep moving characters around from one chunk of memory to another. If you append a single character to a string, you would measure both, add their lengths plus whatever overhead your data representation requires, malloc that much memory, move the characters from each source and then free the memory occupied by the first. The other way to do it is to malloc memory in more or less fixed sizes and include in the header of your variable a length field. With plenty of memory available nowadays, few still choose the first option. Appending a few characters does not require any new memory allocation nor freeing it up. The later method depends on how good where your statistics (more damned lies once again) about the average string length, but if you get it right, appending to a string ( .= operator) becomes as fast as appending to a StreamBuffer, as found in other languages with separate Strings and Streams classes. Some languages do not even require string space to be contiguous so that when one block is used up you don't have to get a bigger one and move everything to the new place, the blocks comprising the string are linked in a list. That's one reason why lots of languages now prefer 'immutable strings', it is no longer possible to treat the string as an array of characters since they cannot be accessed via a simple offset. This benchmark is probably exercising more the symbol table lookups and memory allocation functions than the actual concatenation, since it is allocating and freeing up lots of space for really tiny strings that don't take much of that space at all. Whatever difference there is in the actual string operation might be clouded under other factors. Regardless, I do prefer to use single quotes and, as I mentioned elsewhere, I just echo the bits and pieces as soon as I am able, reasoning that the output buffer is truly a stream buffer and since the echo is a language construct (no function call overhead), it should be faster than managing memory to hold strings. As I said, though, the performance of one option against others varies so much in different trials under different conditions that I feel foolish just to show them. Then, not even logic works fine if you mean to define what is faster and what is not. Sometimes the developers, using profilers and such tools, find a very slow spot and they get to optimize it to such an extent that it works faster than its un-optimized relative, which under equal circumstances would have actually been faster. Using single quotes for PHP strings frees me the double quotes for HTML attribute values without any need to escape them. I have defined CRLF and TAB as constants which I can redefine at any time to an empty string if I no longer care my HTML output to be readable. Since I prefer to keep all values in their native PHP format up to the last moment, and those values have to be passed either through htmlentities(), number_format(), money_format() or strftotime() on output, variable interpolation is out of the question anyway.

Basically, if you are dealing with the memory yourself, assigning it, freeing it, collecting garbage afterwards and defragmenting, you won't resort that much to individual calls to the memory library functions, you just grab a big chunk and manage it on your own.

Re: [PHP] PHP URL issues
I wouldn't do the htmlentities() on the whole argument list. Depending on the Doctype version you have declared and depending how well implemented it is in each browser, it may render the argument list useless. Unless you declared the strictest and latest version of HTML, all browsers will take a plain in between arguments instead of an amp;. Haven't you seen the page source as received by the browser? All browsers give you that option somewhere in their menues. What does the URL look like in the Location box in the browser? Just to know whether the problem is in the assembly of the URL or in reading it back. If the URL shows correctly, try a var_dump($_GET). Show it within a pre section so even whitespace is clearly visible.

Re: [PHP] Data Types Problem
Since in PHP you don't declare variable types, PHP does its best to guess
what you mean with your values and integers have preference to strings, so
your '01' gets converted to a plain integer 1 for the comparison.
Use === (triple) equal in the comparison and it will check for both value
AND type and it won't do any type conversion.

If the above is your exact code, then the problem is one of scope; move
the $wdays declaration inside your convert_from_weekday() function.
I'm more used to C++ than PHP, with global $wdays; it works.
Unless you are using the array elsewhere, it might be a good idea to put it
inside the function so as to not polute the global namespace with variable
names that have no need to be there. In large applications, there is a
non-trivial chance that someone else might use a variable by the same name
and ruin your translation table. It will be slightly slower, though.
As for the localization functions, you might see their effect in:
http://www.satyam.com.ar/int/setlocale/index.php?locale=de_DEsubmit=Aceptar
the input box allows you to enter different locales, the previous URL
already has German selected.
Satyam
However, you may want to investigate the formatting functions of date():
http://php.he.net/manual/en/function.date.php
Date should return names using the native locale; if you want to return
date strings for other locales/languages, use setlocale() -

It's just another way to look at a possible solution.
As for the cost, what are we talking about? I doubt that a typical
application would show any discernable difference in execution times.
One could test this easy enough by running both through 50k loops, but
even then I doubt that the times would be that much different -- but I
may be wrong, been there before.
Cheers,

I don't know if there would be any difference either, which is why it was
a question.
Although Larry's suggestion of making the array static is something I
hadn't thought of.
Overall it is an interesting concept to use an array instead of a switch,
and I do wonder at what point, if any, that the two would start to
diverge resource-wise.
Would the array lookup be faster for a lesser-used option/key in a
situation where there were quite a few options? (you wouldn't have to go
through the whole switch to get to the option at the end (?) or would
you? I have no idea how that all works internally)
Yes, you would. It goes sequentially through each case:. The array, on the
other hand, uses a hashing algorithm so it should be about even no matter
which option you pick.

Re: [PHP] What sripts,helpers to use for AJAX
'Better' is a little subjective and prone to generate a flame war, but I'll risk my opinion. You might want to check Yahoo User Interface (YUI). The Connection Manager at http://developer.yahoo.com/yui/connection/ provides reliable cross-browser JavaScript code for the client side. You might want to check the YUI for other goodies as well. It only deals with client-side Javascript which lets you handle the sever side pretty much whichever way you want it so you are not forced to buy into a whole framework, client and server side, when you don't really need that much. Unless you have good reasons to serve data in XML format, to keep life simple, I would also sugest you use JSON, which is easy to generate (recent PHP versions have json_encode() and json_decode()) and is native JavaScript. On the client (JavaScript) side, I would recomend this functions: http://blog.davglass.com/files/yui/docs/YAHOO.Tools.html instead of those at http://www.json.org/js.html, though the later site is good in terms of explaining and it has a comparison of different JSON functions for PHP, in case your version does not support it.

Re: [PHP] db query not working
I saw two people pointing two errors on the SQL insert statement which you
would have found yourself had you put the 'or die()' at the end of the
query, as someone else suggested. Do never leave any query without the 'or
die()' after it (or any other means to check if mysql_query returns anything
not false). This would have saved lots of your time, our time, everybody's
bandwidth and would avoid your asking everybody again for the next error you
make. We all make errors, none of us is above that, that's why, at least in
my case, I never fail to add the or die() at the end. That's why the
developers of function libraries have put some means of reporting errors
back. It takes time for providing good error reporting. You are wasting
that effort as well.

This let us: 1. create one file (in french) and let someone do the translations 2. provide the 'key users' (admins) of the application a php page that can be used to edit/change these translations 3. include the xml files into our cvs so that changes are managed 4. provide a new language to the application simply by adding the corresponding file if needed, we can split the file on a functional basis to reduce the amount of data to be loaded. Most of the time however, we simply have some form labels, feedback messages, menu items : less than 50 labels per page. So this works very well. Recently a collegue showed us gettext. As it seems very powerful, the main disadvantage I can see is that translations files are not directly editable. The admin users cannot edit the files and correct/change the translations. Moreover, we work mainly on windows and I'd rather minimize the number of softwares needed by the developers to do their work (php editor, oci, mysql, mssql clients, cvs, svn, firefox, moz, ie, uml editor, ... so many already!) So my question is: do you know if there is any way of editing the gettext translation files from a http page? I mean, without the need to execute a 'compile' (or whatever) action on the webserver. You might want to check PHP-gettext at http://savannah.nongnu.org/projects/php-gettext/. Since it reads external gettext files and stores them internally in PHP data structures (well, arrays) you might patch their data structures. Anyway, it might not be better than your current setup. do you have any comment on translating the applications? yes, but they are in Spanish, (http://www.satyam.com.ar/blog/2007/01/17/internacionalizacion-y-localizacion-indice/) sorry, Europeans often are multi-lingual, perhaps ... of course gettext seems powerful, with caching an so on. But I really believe the new SimpleXML can load a translation file very quickly, and php offers enough functionalities to do cache of the labels in the current language... thank you Vincent -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- No virus found in this incoming message.

As you know, if you crypt any string to SHA1, you don't decrypt again. You cannot use username in your application. in my many application, I have crpyted password , I haven't cryrpt usernames. Becuase I used username for session authentication. for example if I want to action on the usernames or list of usernames , what can I do this? All of usernames are crypted. OK then what if i consider using PHP's Mcrypt extension with a key to crypt/decrypt data, this would give me the possiblity to use a username crypted hash in the session variable and decrypt it at any moment with the proper key? One aproach I have often seen to security is making things complicated, assuming that it will deter intrussion. Complicating things, though, rarely achieves anything useful. Being paranoid about some data you might be complicating your own work and that of those who will have to mantain and upgrade the application afterwards for very little gain. There are good and proven ways to secure an application. If you rarely see anyone going beyond those basic rules it is because the pay off is marginal in terms of security but too complicated in terms of mantainability. Take the user name you are so concerned about. Are you subscribed to eBay and get their newsletter? They send you their mailings with your username in clear to let you know it is indeed from them. eBay runs one of the most secure open sites in the world, and they don't mind sending your login name in the clear, and nor do I so, why should you?

Re: [PHP] Language construct
echo, include and a few others are language constructs because they are part of the language itself rather than being functions in the same category as regular functions are. This means that they are integral part of the language, just like 'if', or any operator +, *, etc, though they look pretty much like functions. It means that though syntactically they look as functions and in the manual they are listed under functions, this is only to make them easy to use, understand and locate in the documentation. That is why certain rules for functions can be relaxed, such as requiring parenthesis around its arguments, which are not actually needed but are there so that they have the same look as regular functions.

Re: [PHP] print() or echo
echo is slightly faster than print and it takes multiple arguments so instead of: echo 'p' . $test . '/p'; you can do echo 'p' , $test , '/p'; which should be faster, and I say 'should' just because as print should be slower because it has to go into the trouble of setting up a return value, so avoiding doing a concatenation first and then output the whole thing by just streaming each of the pieces to the output straight away should be faster, though string operations are so optimized as to be neglig well, you can't tell the difference.

Re: [PHP] round to nearest 500?
- Original Message - From: Jon Anderson [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: hah yeah, always worth a little skepticism, but it seemed to make some kind of sense. If you always round up or always round down, that's obviously not right and you end up losing potentially a lot of money or over-estimating the money involved. Founding up for 5 through 9 and down for 0 through 4 seems like it makes some kind of sense, but apparently it doesn't work out that way. I'm sure someone out there knows what I'm talking about (it might be the first time, but I know I'm not making this up hah), but rounding 0.75 up to 0.8 and 0.65 down to 0.6 (or vice versa) is supposed to be more accurate or at least leads to fewer anomalies. Someone feel like writing a quick script that generates random numbers and does the rounding based on these two ideas (doing it the 'hard way') and see how much variation there is after like 10,000 iterations? If I have time later, I'll do it. Now I'm even more curious. I wasn't aware of the accounting trick before today, but I believe I can explain it: If your numbers are statistically random, then the above solution will lead to an even distribution of rounding up and rounding down. The reason is simple: 0: No rounding. It's already there. (8.0 doesn't need to be rounded to 8 - it already *is* 8.) 1-4: You round down - 4 of 9 times you round down. 5-9: You round up - 5 of 9 times you round up. That is not quite correct, there is no such 4 ninths agains 5 ninths. You round down in the interval from 0 to0.4 and you round up from 0.5 to 0.999. If you substract the .5 from 0.9, you get 0.499 so it is about the same interval for both. If there is any difference, and actually there is, is because any number is, in reality, truncated, and not rounded, at some point. Depending on the number of bits of the mantissa, it might be a long way off, but eventually, it will happen, and that one is truncation, nor rounding, and if you repeat any calculation involving fractional numbers, it will eventually add up to something noticeable. Actually, there is the further problem that computers actually use binary, not decimal, so they cannot represent decimal numbers exactly. To offer an example of what I'm talking about, 1/3, which results in a never ending 0.33 is exactly 0.1 in base 3 arithmetic! Conversely, many 'round' numbers in our decimal notation are not 'round' in binary and viceversa. So it is all the piling of lots of rounding errors in real-life number representations that produce the error, not the mathematics of rounding, which actually work in an abstract world of infinitely precise number representations (in other words, infinite bits to represent any numbers). Satyam So you round up 11.1% more often than you round down. As a result, if you round up when it's odd, and down when it's even, you eliminate the 11.1% difference in when you'd round up then round down. That said, if someone were aware of the above rounding trick, it wouldn't take someone very much effort to come up with things like fee structures or pricing structures that could take advantage of that scheme to force rounding errors to remain permanently in the person's favor. I certainly hope that PHP continues to use the standard technique, and not the accounting trick above. :-) jon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- No virus found in this incoming message.

Re: [PHP] How to parse PHP tags in a string?
- Original Message - From: Zak Mc Kracken [EMAIL PROTECTED] Hi all, Is there a PHP function that parses a string as it was the content of a PHP file? I have a CMS application and editors write the news items text into a text area. Since they have some knowledge of PHP, I'd like to allow them to insert ? ... ? or ?= ... ? and have the content blocks parsed and executed. OK, this could be easily done parsing the string and passing the block contents to eval(). However I wonder wether there is some function already doing that (maybe in a more efficient way). I would not recommend you do such a thing, you are opening up all the PHP environment to the editors, including reading variables and calling functions they whould see nor run. Instead, I would sugest you allow them to embed within the text a series of functions or variables which you would define, enclosed in whatever symbols you find suitable (easy to search and unambiguous) which would allow your program to replace by whatever data you may provide for them to use but in no case I would open up the whole of the PHP environment to them. You would pick those functions with a regular expression and do a switch on the keyword found and process it. Thus each keyword would have a case to process it and might call a PHP function or read a variable, but no 'default:', if it is not within the allowed functions, forget it.

At least as of MySQL 4.1 (haven't played with MySQL 5 much yet), yes, MySQL has no native boolean data type that I know of. The standard alternative is TINYINT(1), which technically gives you values 0-9. And yes, I agree that MySQL has fairly decent date manipulation routines.

Subject: Re: [PHP] SQL Readability.. (was Re: most powerful php editor)
I have long since given up on raw insert/update/delete statements as the
syntax is all kinds nasty. These days I just do this, which is even
easier
and more powerful:
http://www.garfieldtech.com/blog/simplifying-sql
I tried the following:
insert('sometable',array('when' = mktime(0,0,0,2,1,2007),'if' = true));
which produced the following SQL statement:
INSERT INTO sometable (when) VALUES (1170284400,1170284400)
The problem is that PHP types do not correspond to SQL types. Though a
boolean does identify itself as such, a date never does. Your switch() on
the gettype() of the value misses the type 'boolean' so it falls through the
default: case which then appends whatever was left from the previous pass.
However, even adding a case for type boolean there is no way to recognize
dates since they are no more than integers for all PHP cares. Finally, what
happens with an expression that produces a sort-of boolean, like anything
non-zero for true?
Those are the reasons I used type modifiers in my BuildSql function
(http://www.satyam.com.ar/int/BuildSql.php), I couldn't rely on PHP figuring
them out correctly. This also allowed me to expand those modifiers to
optional positional modifiers and null handling ones.
I even tried to query the SQL engine to report them back, but that was also
unreliable, MySql for one, reports the type of what it used to store it, not
what you declared them to be. Thus, for a boolean field it will report
integer, but if you try to store a number other than 0 or 1 it then
complains. So, unable to get reliable information from either end, I
decided on stating the type explicitly on the query string.

about the dreaded error involve # of columns not matching.
Only things you have to watch for:
1. Make sure you don't have a comma on the last item
2. Make sure you have spaces where appropriate so when it concatenates
the
strings, you don't get stuff crammed together (not really an issue with
the
INSERT statement, but I try to keep a consistant practice with all my
queries so I don't slip up.. SELECT columnsFROM tableWHERE something =
something is where it really gets ya if you forget spaces.. just as an
example) 3. Make sure to remember to concatenate the query and values
parts
I like to think this is a little outside the box thinking since common
practice is one command, one line or total chaos hah.
Any comments on improving this or other unique stylistic ways people like
to design their code?

I use to build SQL statements with a BuildSql function, which you can see
at: http://www.satyam.com.ar/int/BuildSql.php
It is commented in PhpDoc format.
For example:
echo BuildSql('Insert into ?ptable
(?s,?ns,?mi,?d,?ni,?i,?t)','Something','',5,time(),0,null,mktime(3,4,5)-
mktime(0,0,0));
Will return:
Insert into wp_table ('Something',null,5,'2007-01-21 15:54:27',null,0,'0
04:04:05')
It is not only meant to build inserts but it is more like a sort of
SQL-oriented sprintf(), like it does proper handling of null values, such as
avoiding puting the text 'null' (notice the quotes) instead of the value
null. It also has a ?p 'prefix' modifier to use a fixed prefix on all table
names.
As for formatting, I usually put the SQL statement in one line and the
arguments in the next one with spaces to align them vertically, which I
won't show here since the formatting of the message will ruin it anyway.

Re: [PHP] Forms and destroying values
As many have already replied to your question, what happens is that upon a refresh the browser is resending the original post variables again. The unset() does work, from the point of the unset() to the end of the script (when all variables except for session variables are unset), PHP will have completely forgotten about those values. But that does not affect the browser at all. On a refresh the browser will send the information again, unless it is tricked via a redirection command to believe the URL used for the post is obsolete. Then, what the browser will do is to remember the URL it was redirected to and drop the 'obsolete' URL so, when the user does a refresh, the browser will be smart enough to go to the 'updated' (the redirected-to) URL instead of the original 'obsolete' one and thus will get the confirmation page again, but without passing through the database transaction.

[PHP] Using gettext
I decided to internationalize a program that I already had and part of that process was to put the existing texts under gettext(). So far, when I meant an application to be localized, I made the original in English, but this one was already in Spanish. So, now, I have the source strings in Spanish with many letters with diacritical marks, accents, tildes, umlauts. Though the .po file says they are in ISO-8859-1 and, indeed, they are coded in that way, gettext finds the translations for the string which happen to contain no diacritical marks but fails on any string that does have any. Nevertheless, it does understand and render correctly those same 'special' characters as translations, as long as they are translations for strings that don't have any such. This would indicate it is understanding the character encoding correctly. The GNU manual doesn't say there is any limitation as to the character set of the input file, after all, that's why it can be specified in thhe header. So (characters with diacritical marks might not display correctly in your mail client): # this translates fine: msgid Pedro msgstr Peter # this translation is not found: msgid José msgstr Joseph # this works fina as well. msgid no diacritial marks in this string msgstr plenty of them: áéíóúüñ I'm using Windows XP and used poEdit from the GUI interface and I also run the msgfmt utility from the poEdit package and the one from the GNUWIN32 project and the result is the same. I also copied the .mo file to the *nix server of my ISP and the result is exactly the same. The setlocale() function succeeds (though with different values in each system) since, after all, it does translate some of the strings. I also tried the gettext implementation from WordPress, wich comes from the PHP-gettext project (http://savannah.nongnu.org/projects/php-gettext/) which does not use the standard PHP library functions but solves it all in PHP (without functions) so it works whether the locale is installed or not, whether the PHP has gettext support compiled and so on. Using this, it works fine with all string, so the .mo file seems to be fine. Actually, it works just nicely without using setlocale, bindtextdomain, textdomain or any of all those complications, whether your ISP has gettext compiled into their PHP, you just tell it where the .mo file is and it reads it into an array. I wonder why I care about the 'official' gettext at all, but I'm curious to learn, so I ask.

Wyss Besides what Jochem has already sugested, I would add that I usually have in the include file, in an unaccessible path as he said, a function that returns a connection. The function has all the connection information local, so that they are neither global variables nor constants, just local literal values within the function. I'm sure most people end up with some kind of abstraction in the form of a class or function to do all the 'heavy lifting' regarding connecting to the DB, etc - but when projects get rather large and/or your faced with a situation where you want/need to run your project on different systems (e.g. local-dev, test/staging, live) it often most handy to place all installation specific configuration values in a single file that is specific to the given installation and therefore usually not included as part of the version control (e.g. CVS or SVN) module that stores the projects files. No problem there, the include in my DB abstraction layer includes and calls the separate file with the function to make the connection to the database. Though the main application source doesn't know about the include file with the connection data in it, the DB layer include does. In this way, I have the db include file under CVS and can refresh it at the production server without a problem, while the include file with the connection is separate, so that I have one for the test machine (this one) where the server is 'localhost' which I never copy to the production server. Nevertheless, I admit that the important issue here is to have the connection data out of the public folders, mine is just a useless paranoid complication. Does anyone have an expression evaluator in an application open to the public? Does anyone make a var_dump of $_GLOBALS on error (and then forgets to strip it out on production code)? I sure hope not. In the same function I put the call to mysql_select_db. Though I check the return values for errors, I usually ignore them since unless you have either more than one database engine or more than one database, the default link resource does not need to me explicitly passed to other functions.

It is part of a table with currency codes. Each row has 4 cells containing
the country name, the currency description, the currency code and the
numeric code, as seen in the first row. Nevertheless, with countries that
have more than one currency, it still has a single row with the first cell
containing the country name (see BHUTAN) but then in the following cells it
has several lines, one for each currency, as simple paragraphs.
When I get to the row for BHUTAN, I do a foreach to see what's in each cell.
Function dump() just does a var_dump() of whatever is given in the first
argument within a pre tag and uses the second argument as a heading,
surrounded by dashes. In this case I copied the expression of what I am
dumping as the title (within single quotes so it does not expand).
foreach($row as $cell) {
dump($cell,'$cell);
dump($cell-p,'$cell-p');
dump((array)$cell-p,'(array)$cell-p');
dump($cell-p[1],'$cell-p[1]');
}
The section in question is shown below. Though $cell is shown as a
SimpleXMLElement containing one 'p' property which contains an array of two
elements:
$cell-
object(SimpleXMLElement)#8 (1) {
[p]=
array(2) {
[0]=
string(12) Indian Rupee
[1]=
string(8) Ngultrum
}
}
If I dump that 'p' element, I don't get an array but an object with just
one element, the first value in the array
$cell-p-
object(SimpleXMLElement)#7 (1) {
[0]=
string(12) Indian Rupee
}
If I typecast it to an array, I still get a single element
(array)$cell-p-
array(1) {
[0]=
string(12) Indian Rupee
}
Nevertheless, if I explicitly index into the 'p' element, without even
typecasting it into an array, the second element is there.
$cell-p[1]-
object(SimpleXMLElement)#10 (1) {
[0]=
string(8) Ngultrum
}
So, now you see it, now you don't, or do you? What's happening?

Re: [PHP] Handling SimpleXMLElements

From: Jochem Maas [EMAIL PROTECTED]
I'm guessing you have php5.0.x running - you really want a php5.1.x
PhpInfo reports it's 5.2.0 so I'm covered there.
version if your going to use XML - it will avoid *alot* headaches with
regarding to using var_dump() (or print_r() or even echo) to figure out
what the simpleXML objects are/contain.

Re: [PHP] Security with dbHost, dbUser, dbPassword
- Original Message - From: Otto Wyss [EMAIL PROTECTED] What is the usual save way to store/use DB access info in a script. I currently just use some PHP variables in a file which I include in all other scripts. config.php ?PHP if (!defined (config_include)) die (Error...); $dbhost = localhost; $dbuser = name; $dbpass = password; $dbname = database; $dbcoll = utf8_unicode_ci; ? Is this save enough or are there better ways? Where should I store this file so it isn't accessible via the net but inside scripts? O. Wyss Besides what Jochem has already sugested, I would add that I usually have in the include file, in an unaccessible path as he said, a function that returns a connection. The function has all the connection information local, so that they are neither global variables nor constants, just local literal values within the function. In the same function I put the call to mysql_select_db. Though I check the return values for errors, I usually ignore them since unless you have either more than one database engine or more than one database, the default link resource does not need to me explicitly passed to other functions.
