[PHP-DB] Do the included PHP MYSQL calls work with MYSQL 4
I have recently built PHP 4.3.2 using the --with-MySQL, but heard a rumor that the PHP built in libraries to MySQL are old and not completely compatible with MySQL 4. Does anyone out there know if this is not a concern...does the built in MySQL interface in PHP 4.3.2 work with MySQL or do I need to go another route. Thanks in advance... - Richard -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] MySQL and PHP?
Hello I hope this is a rumour but I heard that MySQL is now fully GPL which it wasn't earlier. I think the part used to communicate with the mysql server was lgpl. Does this mean that when using php with mysql your php scripts have to be licensed under the gpl as well if released? If this is the case what other free sql databases are there that can be used with php?

A "user" only has access to the server-parsed php files (whether they are using a browser or telnetting directly to port 80). They don't have filesystem access. Now, if you have open/poorly secured ftp/sftp/scp/telnet/ssh ... access, someone who can utilize that route will have fairly unconstrained access to your site and its contents. However, that's basic access control security and not a php-specific issue. If it's contractors/co-workers who have filesystem access to the site, in order to manage content, then you have a trust issue. If your concern is with others "on the site" (e.g., a shared hosting environment) then you have a basic hosting security issue, and problems well beyond the control/scope of anything php. - Richard -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You are saying that you have written a POS system in interpreted code, without an interface/wrapper (much less client/server separation), so for someone to use it they can have direct access to the (plain text) code files? In my book, this type of setup wouldn't pass the most basic security audit, and I can only imagine the potential issues with pci and hippa (assuming the latter given your previous posts). You haven't indicated the OS. If it's windows, I think the bets are mostly off. In a *nix environment, you can control writes with ownerships and file permissions, but with interpreted code the (plain text) files need to be readable. Given what you seem to be trying to do, I don't think that chrooting the worker's login will work. You may want to look into "kiosk mode" options -- for both windows and *nix -- as that generally disables access options other than the controlled interface. In a *nix environment I would probably start with VMs in order to provide client/server separation, but still on a single box. Of course, all this is well beyond the scope of the php-db (or even php-general) list. You should really take your questions to os-specific security/hardening lists. - Richard -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Re: Code Security
But the fault here isn't with PHP. Ethan couldn't do what he wants, the way he seemingly has things set up, with any programming language. Compiled code might let him obscure things a little, and also potentially help hide the credentials used to access the db, but it would still be a totally insecure environment. In a *nix environment (note -- I don't think it's clear what OS he is using) you might be able to chroot the "user". This would mitigate things some, but there are still many holes. He could set up VMs on his single physical box and get client/server separation that way. That would improve things markedly. In the end, however, the "user" has direct control of the physical box which leaves a range of options for access to the [user] data (which is more important to protect than any code) that should cause this setup to fail even fairly basic security audits. There are ways to approach this, but it seems to need rather serious re-engineering -- with data privacy and security as the key element. - Richard Original Message > Date: Wednesday, February 18, 2015 10:14:43 -0500 > From: Mark Murphy > To: Taco Mathijs Hillenaar-Meerveld > Cc: php-db@lists.php.net, Guru , Karl DeSaulniers > Subject: Re: [PHP-DB] Re: Code Security > > @Taco, Read back through the whole thread and you will understand. > Ethan just can't do what he wants to with PHP. > On Feb 18, 2015 9:59 AM, "Taco Mathijs Hillenaar-Meerveld" < > tm.hillen...@gmail.com> wrote: > >> Sorry if i misread and put my reply in a wrong context. >> but from how i read this question it is all about preventing a >> user to open a terminal window. >> >> if Mr. Nice is logged in then i assume he has all rights as the >> topic starter is afraid Mr. ugly can look at his code. >> >> as far as i know it is not common practice to work direct on a >> server and have all rights and allow other people using that >> computer when connected to the specific server. >> Ethan also pointed out that he made a POS (Point of Sale) program >> to work in that store. there are 2 account types: 1>admin >> 2>worker. >> >> the worker should not have any rights and the admin account >> should only be able to change/edit things within that program. >> >> >> i don't see why anyone (the admin included) would need to have >> access on the stand alone server apart for maintainance duties to >> keep it all up and running. >> the server needs to be locked in a server room or another place >> that will fit. but definately locked. >> >> if someone can get on that server through a terminal it will mean >> something has gone horrible wrong. >> >> i am not sure if Ethan is trolling though. but if i understand >> his question right and it's a honest question, it sounds kind of >> weird to me. >> >> when i get an order to install a server, my first question would >> be like: - who is going to use it? >> - who has access to it? >> - who need to have access to it? >> - where will this server be placed?

As I said:

These errors look odd to me. In many years of working with apache on
a range of *nix OSs, I don't remember a (properly installed) apache
instance that didn't have defaults that worked out of the box. They
may not have been what one wanted, but they worked.
With errors like these I wouldn't expect the web server to start,
but from previous exchanges I thought that it/one was running. Are
you running more than one server? What do ps and netstat show.
As these are web server, not php (and certainly not php-db), issues
you should probably be asking them on the apache list.
[i read the list, please do not include my direct email address in

As I pointed out on the apache list, 127.0.1.1 != localhost. It's
not clear where all you've stapled that incorrect value in at this
point, but that will account for why apache gave you that error.
In the php code, you are not handling the output from
mysqli_fetch_array correctly. Read the documentation, there are many
examples -- including q/a responses that almost exactly match your
code.
You have shown no debugging effort on "HandleWeight", so we have no
way of providing any insights on it.
You additionally need to provide the version/release level
information for your installed versions of:
- OS
- apache
- mysql
- php

What "Never connects. Hangs" -- your test php page, or HandleWeight?
In either case, that and the "Debug" code that you included above is
basically useless for determining your problem(s). You need to work
through your code from the top, bit by bit, until you know that each
piece to that point works. Put in "if $debug" statements (or
whatever approach you want) so that you can see exactly what's being
returned at each point. This is "programming 101" level debugging,
and something that many of us have suggested over many months of
trying to help you.
[As an aside, you may have fixed this, but you have had 127.0.1.1
listed as "localhost" somewhere (/etc/hosts, apache config, php
code). That won't work. Set the IPnumber for "localhost" to the
correct value.]
I don't have any more time for this. Good luck.

If set up under a user -- which is the better approach for general use -- they will run as that user. Really only system-type cron jobs (that require root access) should be set up to run as root. If you use the command: crontab -e from a user account, then the crontab is set up as that user. The first 5 fields/values are time/date related, followed by the command to be invoked.

So, if your mysql authentication is set to accept connections/give access to say the user your web server is running as (which is how php will show by default), then you will either need to pass those credentials in your cron job php script or, give the user that's running the cron job access. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The user that is running the script will be the user that the cron job is set up under. If you set up a cron job as a standard user you can't assign it to run as a different user. If the issue is mysql access, you do that just the way you would in a [web]server parsed php file. The script is whatever you put on the crontab line. The script you reference from the crontab entry can be a shell script that does some setup, and then calls your php script. Your php script can have include files (e.g., for mysql connection setup) just as you might have in a [web]server parsed php file. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP-DB]Question on select..for update
Hi, just started on the list, and the didn't seem to get through the first
time, so I'll give it another whirl.
I'm trying the following code based on a modded db_oci8.inc (the mod is so
that the call to OCIExecute always passes OCI_DEFAULT rater than
OCI_COMMIT_ON_SUCCESS.
This is a snippet of the relevant code:
The variable $PartNumber contains the part number to query on:
$db->Query("select part_nbr "
." from psns "
." where part_nbr = '".$PartNumber."' "
." for update ");
$db->next_record();
?>alert ("Waiting with record lock")Query("lock table psns in exclusive mode");
?>alert ("Waiting with table lock")Query("update psns set user_id = '' where part_nbr =
'".$PartNumber."' ");
$db->Query("commit");
The problem is that between the firt select query and lock table there
should be a record lock on the requested record. Now opening up a SQLPlus
session I can perform an update on that record. If, from SQLPlus, I try and
lock the table or do a select for update, then this the locking works fine
and there is no problem, so I know it is not an oracle related problem
becuase of this.
I've tried this also with the OCI8 libraries and the same problem occurs.
What I don't understand is why this should occur, after all its just passing
SQL queries through and not doing anything else flash.
Between the table lock and the update the lock should also be placed at
table level, yet there is still no lock applied.
The results in debug mode are :
Obtained the Link_ID: Resource id #3
Debug: commit mode = 0 COMMIT On success = 32 Default = 0 (this is just to
check that the mode is OCI_DEFAULT)
Debug: query = select part_nbr from psns where part_nbr = 'XX' for
update
[PART_NBR]:XX
Debug: commit mode = 0 COMMIT On success = 32 Default = 0
Debug: query = lock table psns in exclusive mode
returned Debug: commit mode = 32 COMMIT On success = 32 Default = 0 (this is
just to check that the mode is OCI_DEFAULT)
Debug: query = update psns set user_id = '' where part_nbr = 'XX'

RE: [PHP-DB] Parse error on array and SQL query
If you're not getting the parse error anymore, I'd suggest you echo $query
to the browser and check to see that the SQL statement is what you expect it
to be. Can't count the number of times doing that has pointed out some stray
apostrophe or comma or something that killed the query.

RE: [PHP-DB] Redirect.
Don't know if I fully understand your question, but, in general, you can
handle redirects with the header() function, e.g.,
header("Location:
http://www.yoursite.com/yourscript.php?msg=0&storyID=".$newstory."";);
As you can see, you can include variable=value pairs at the end of the URL
as well (msg and storyID in the example above).
Check for the header() function in the documentation on php.net for
additional information. PHP-GENERAL, as suggested by another user, is the
most appropriate and possibly more helpful mailing list for your particular
question.

[PHP-DB] Selecting every 50th row
Hi php-db, I have a table with approx. 250,000 rows in it. The primary key is an ID field. All I am wondering is - is there any way at all from MySQL to directly select every 50th row in this table? I.e. row 1, 50, 100, 150, etc and return the ID of each row, ideally with some kind of limit. Even if it was only possible to select the IDs of two rows, i.e. row 1 and row 50, that would be good too. It's almost like I need a "step" function, like in a FOR NEXT statement, only SQL-side. -- Best regards, Richard mailto:[EMAIL PROTECTED] -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No, because by that point the Header has already been sent. You can't issue a cookie after a header has gone and use it in the same page session. As the PHP manual so elegantly puts it - this is a protocol restriction. Your browser will look for cookies at the start of the page request, not in the middle of it (where your image is).

You're building a select list of 2500 elements? No wonder it's slow.
That must be generating a few hundred KB's worth of HTML on its own,
let alone anything else on the page.
If you're not using all 2500 rows, you need to optimise your query to

If you profile your query you'll notice that in say a 10,000 record table, if you LIMIT 0,50 but order by something generic (say an ID or date stamp) it'll still order all 10,000 records before returning the 50 you asked for.

I wish it did. Rarely in practise do I ever see this happen. I wonder if it's version specific?

RE: [PHP-DB] multi-language site
$.02 from a technical writer: If you're going to translate your content from English directly to a foreign language using machine translation (which is what gettext would amount to) be very careful. There is a difference between translation and localization. The free Babelfish service is a good example of translation. You'll get a word-for-word translation of whatever you want to type in the English box. However, what shows up in the translation box is not always what you meant in English. Have you ever bought a Japanese product whose instructions read: "Use caution when opening my box. I wormhole swimming pool orange piranha yesterday, sir." Your best bet may be to write all of the English text, have it translated and put into XML files as Ignatius suggested, then use PHP to set/retrieve cookie settings to display the proper language. I can personally vouch for the difference between text that has been machine-translated only and text that has been machine translated and reviewed/corrected by a human. Machine translation cannot match a human's ability to compensate and account for context and usage. There are quite a few localzation companies (SH3, VistaTec, SDL International) who specialize in translating content for web sites even in XML format. Send them an English XML document, they'll send you a Spanish one back without messing with your tags - only the content gets translated. Of course, it DOES all come down to dollars and cents and how important the translation really is; only you can decide that.

Tris, Here's what I found on infoworld.com in a very limited search (dated 1/12/04). There is info in there that should provide you with other avenues of research to clarify your company's responsibility. Here is a relevant excerpt: "CAN-SPAM [went into effect Jan 1., 2004] requires that spam e-mail include a working return e-mail address, a valid postal address for the sending company, a working opt-out mechanism and a relevant subject line. The law also directs the U.S. Federal Trade Commission (FTC) to study setting up a national do-not-spam list, similar to the national do-not-call telemarketing list now in effect." And the relevant link: http://infoworld.com/article/04/01/12/HNspamcomply_1.html So, in a not-so-thorough examination, it does not look like an "opt-in" link is required. Although, it would seem that the Federal Trade Commission's website (www.ftc.com) should provide additional info for the US.

Normally, you get that warning when you've already sent display information to the browser before you attempt to use the header() function. You need to make sure you haven't sent ANY HTML to the browser prior to the header() line in your code. You can check the PHP documentation regarding the header() function.

RE: [PHP-DB] What's wrong with this query?
Been kind of following this thread off and on... If the syntax is acceptable by MySQL, which it appears to be, is it possible that the variables you are using within the query string are not set to anything? Or is it possible that there is something broken immediately before the query string is fired? Most times, when I run into query problems, immediately before I send the query to the database, I'll echo the statement out to the browser so I can see the exact string that's being sent to the db. So can you do this: $sql = "INSERT INTO log SET term='$search', returns='$arrayword', time=CURTIME(), date=CURDATE(), ip='$ip'"; echo $sql; $logit = mysql_query($sql) or die(mysql_error()); And check out what gets spit out to the browser when $sql is echoed? Maybe that'll point out something that's going wrong. If nothing is apparent, post the results of echo $sql back to the list and maybe one of us will find something. HTH.

You don't check $v_dec in your manage.php script though, you check to
see if $page_no is set which it never will be, because no-where do you
give it a value.

RE: [PHP-DB] my code
For one thing, your column name Long is invalid. It's a reserved keyword in
MySQL. Either enclose it in backticks or change the name of the column.
If you want to see what the db is reporting, do this:
$result = mysql_query($query)
or die(mysql_error())
And see what the database tells you.

[PHP-DB] Optimising LIMITs
Hi all, I have what is probably a quite standard question and would love to know how you would all approach this scenario: I have a table in a database that has approx. 190,000 records in it. The table is currently 128MB in size and I'm happy that it is well constructed with no data duplication and sensible indexes. I'm using MySQL 3.28.58. and my question is about querying this volume of data efficiently. The table holds forum threads (several years worth) so a common query running on the table is to bring back the top 50 or 100 threads from a board within the forum. To do this I'm using a LIMIT on my query and for the paging through the data (i.e. the first 100 threads, the next 100, etc) I use the LIMIT n,x syntax. Threads are sorted by date (most recent to the top). This is fine and it works well but I'm concerned it's not the most efficient way to do this because the use of LIMIT is causing the whole table to be scanned each time. Here is a typical (simplified) query: SELECT * FROM thread WHERE thread.status='L' AND thread.boardid=1 ORDER BY created DESC LIMIT 100,50 This takes over 1.02 seconds to process. Running an EXPLAIN on my query shows that it's using one key (boardid), but in the Extra field it shows it is having to use a filesort on the data. 5701 rows were used in order to bring back the final 50 - that's every single thread for this board. What I'm trying to figure out is a more efficient way of selecting a block of 50 or 100 records from any point in my table without MySQL needing to sort/check them all first. One thought I did have was that the Primary Key on my table is called threadid - and I thought that instead of bring back the data in my original query, I could collect nothing but the thread IDs and then use a separate query that does something like: "SELECT * FROM thread WHERE threadid IN (...)" (where ... = all of the IDs previously selected). Would the fact that threadid is my primary key make the original LIMIT/sort faster? Any thoughts appreciated. -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

For example if I view the data in my table I can see the IDs like this: 1 2 3 250 5 6 323 (etc) This is simply where MySQL has gone back and re-used an old slot for a new record.

With regard to disk seeking, here is my table structure:
CREATE TABLE `thread` (
`threadid` int(10) unsigned NOT NULL auto_increment,
`site_user_id` varchar(32) NOT NULL default '',
`boardid` tinyint(3) unsigned NOT NULL default '0',
`subject` varchar(200) NOT NULL default '',

`created` timestamp(14) NOT NULL,
`status` enum('L','P','H','D') NOT NULL default 'L',
PRIMARY KEY (`threadid`),
FULLTEXT KEY `subject` (`subject`),
KEY `boardid` (`boardid`),
KEY `site_user_id` (`site_user_id`),
KEY `created` (`created`),
KEY `status` (`status`)
) TYPE=MyISAM;
As well as moving the subject field to another table (because it's the
only non-defined length field), would another way of speeding up the
disk seek be to turn it from a varchar(200) into a char(200)? I know
it means a larger table size, but MySQL should then be able to
calculate exactly where to jump to in the file?

I will look at this now.
I had been toying with the idea of creating a cache table that held

instead of having to query the database unless they go beyond that 200

Your comments (and MySQL manual posts) have been very useful, thank

Re: [PHP-DB] Re: Alterations + all numeric tables

Tuesday, March 2, 2004, 2:05:44 PM, you wrote:
PL> 398(rows) * 37(average) = 14KB, sorting is more faster
PL> etc...
I have been reading over the MySQL Manual today (specifically the
Optimisation sections) and one thing caught my eye:
"In some cases, MySQL can read rows from the index without even
consulting the datafile. If all columns used from the index are
numeric, only the index tree is used to resolve the query."
I have followed your advice and moved the variable length and char
fields out of my core table so all I am left with are the following:
threadid int(4) unsigned primary
boardid tinyint(3) unsigned
modified timestamp
created timestamp
status enum('l','p','h','d')
My question is - if I change the status field from an enum to a tiny
int (so L=1, P=2, etc) will MySQL consider the table to be purely
numeric? Or would the timestamps stop this from happening? If it does
then maybe I would see some more performance increases.

RE: [PHP-DB] mysql_num_rows
Craig,
First off, where is the $db variable being set? You include it in:
$result = mysql_query($query, $db);
which is line 65, but, according to your function, it's not passed into the
function as an argument and I don't see you setting $db equal to anything
inside the function.
Second, why are you checking
if(!$query)?
You set $query to the string
$query ="SELECT username FROM users WHERE username=('$username')";
so why would it never NOT be set? Maybe you mean to check to see if the
query produced any results? In which case you should probably be checking
if(!$results).
Additionally, you should probably add an or die(mysql_error()) after your
mysql_query... line to display errors from the database.
And if your query process fails at line 65 because $db isn't defined, then
line 70 won't work because you haven't performed a query to return any rows.
Hope this helps.

RE: [PHP-DB] No data being put into the DB
Yeah, I prefer the ... '".$_POST["varname"]."' ... syntax primarily because
of the way my editor (EditPlus) highlights the code. I tried the braces
syntax in EditPlus and it doesn't highlight the same way. I'll check out the
editors you guys (Jason and Jeffrey) use to see if I like them and maybe
I'll switch (especially if they're free :) ).
I'll admit, the whole quote-dot syntax thing is a bigger pain than the
braces syntax. But I'm not aware of any performance or security issues
related to the use of quote-dot notation. If there are any, I'd certainly
like to be made aware of them. However, I think it comes down to issues of
personal preference and the coding standards of your individual corporate
environment or client.

RE: [PHP-DB] Php datetime
You also have the option of changing the column type to TIMESTAMP. With a
TIMESTAMP column you don't have to do anything to get it to update
automatically. Just do an INSERT into the table and the column will be
updated automatically.
Here's a snippet, but check the full MySQL documentation for more
information.:
"Automatic updating of the TIMESTAMP column occurs under any of the
following conditions:
The column is not specied explicitly in an INSERT or LOAD DATA
INFILE statement.
The column is not specied explicitly in an UPDATE statement and some
other column changes value. (Note that an UPDATE that sets a column to the
value it already has will not cause the TIMESTAMP column to be updated,
because if you set a column to its current value, MySQL ignores the update
for efficiency.)
You explicitly set the TIMESTAMP column to NULL."

RE: [PHP-DB] Multiple deletes and updates...
Are you thinking about something like (off the top of my head, untested):
for each of the people listed on your page?
Then, in the script that handles the updating stuff, you simply do a
foreach($_POST["update"] as $value){
$sql = "some UPDATE query using $value";
}
foreach($_POST["delete"] as $value){
$sql = "some DELETE query using $value";
}
to send information to the database? Depending on your requirements, you
might need to determine whether the data should be DELETEd or UPDATEd, but
that's not too tough either.
One suggestion would be to consider using radio buttons instead of
checkboxes to prevent somebody from accidentally checking both DELETE and
UPDATE then causing some sort of problem.
Hope this helps.
P.S. What the heck does chocka mean?

[PHP-DB] How do you make an IN span multiple tables?
Hi, I'm a bit stuck with the following: I need to select data from 3 different tables and want to do it via a SELECT ... IN query. Each table has a primary key called thread_ref. I would like to do something like this: SELECT * FROM table1, table2, table3 WHERE thread_ref IN (1,2,3,4,5,6,7,8,9,10) Now the problem is that MySQL complains about the thread_ref being ambiguous - which I know that it is. But putting a table name in-front of it will limit the IN query to that specific table and cause no results to be returned. It is possible that not all of the tables will contain all of the thread_ref's in question. Does anyone have any ideas or is it just not possible using this method? I'm not using MySQL 4 otherwise I would have looked at using a UNION. -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi all, Sorry for such a newbie question!

I.e. what is the difference in possible maximum values held between an INT(10) and an INT(4)?

RE: [PHP-DB] Pulldown value not passed to next page
Karen,
I'm assuming that when you say:
> For some reason,
> when Previous/Next are clicked, the value passed is still 15
> even though the pulldown says something else (5 or 15 or
> whatever)
you're drawing that conclusion because 15 images (or whatever) are displayed
on the resulting page regardless of what you select in the pulldown. Does
the actual URL say 15 or does it say something else (e.g. 20)?
If the URL shows that pagesize=15, but the resulting page displays 20
images, it's possible the problem is that you're not checking the actual
value passed in the URL.
Your current code:
If(!$pagesize)
{
$pagesize=15;
}
Should read:
If(!$_GET["pagesize"]){
$pagesize=15;
}
Else{
$pagesize = $_GET["pagesize"];
}
This is assuming that you have register globals turned off (I think that's
right). Because, otherwise, each time the page loads with your current code,
$pagesize would never be set and would always default to 15.
Hope this helps.

RE: [PHP-DB] How to redirect after a valid login
Not to mention, the header() statement is being used incorrectly in the
example code.
You don't echo out the header() statement. You simply use it.
For example...
In your sample code, you include("mainmenu.php") which looks like it would
output to the browser. You can't to that on the same page you use header().

RE: [PHP-DB] MySQL Logging
Hi, You could do something like tail -n25 /var/log/mysqld.log | mail -s "Database Logs" [EMAIL PROTECTED], and run it in cron. For logging, if you want to log queries, you would use mysqld --log=/var/log/queries.log, but I'm not sure this is the type of logging you're looking for. What might be a better idea, is do the mysqldump, dump everything to a text file, then, at the end of the text file, append the date so that it looks like: INSERT INTO 03/13/2004 Then, just tail the last 10 lines of the text file, and you can verify a couple lines of data as well as the current date. Worse case, you have to restore that data, you just have to remove the date.

I'd recommend you search the PHP archives for an answer. This question comes up a few times a year and the last time I remember seeing it, somebody (John Holmes, I think) provided an excellent discourse on the different ways to approach this solution.

RE: [PHP-DB] Where's the error?
I think you're right, Robert. Hopefully, your editor has a Match Brace
feature or something similar so you don't have to search manually. You also
might want to raise your level of error reporting in your PHP.ini file so,
in your testing environment, those errors get spit out to the browser. It'll
save you some time searching around. Up to you though (obviously).
Happy hunting! ;)

You can also use ini_set() in a script to change the directory for that specific script. However, as others have stated, the directory must exist and the Apache user must have permission to write to it. I don't know if ini_set() is any more/less secure than changing the php.ini file.

In other words, don't hesitate to use require() if you want a missing file to halt processing of the page. include() does not behave this way, the script will continue regardless. Be sure to have an appropriate include_path setting as well." And.. "The include_once() statement includes and evaluates the specified file during the execution of the script. This is a behavior similar to the include() statement, with the only difference being that if the code from a file has already been included, it will not be included again. As the name suggests, it will be included just once." > -Original Message- > From: Mikhail U.

RE: [PHP-DB] Remove white space?
Robert,
ltrim() or rtrim() to get rid of the whitespace if it's at the beginning or
end of the data.
strtolower() to turn the string into all lowercase characters.

RE: [PHP-DB] question on
You'd have to take the value of the first select box in your form and pass
it to another script. You can do that by setting the form's ACTION property
to either GET or POST. Personally, I prefer POST.
In the script to which you submit your form, you can access the value of the
select object thusly: $_POST["varname"] and insert it into your query
however you want (using the appropriate input sanitization methods).
The important concept to understand here is that you cannot use PHP to drive
the contents of your second select object without a round-trip to the
server. Since PHP is a server-side technology, it HAS to work that way.
To make a client-side solution possible, you'd have to send ALL POSSIBLE
data to the page all at the same time then manipulate it with JavaScript.
You can make it LOOK like a dynamic solution by repeatedly resubmitting the
page to itself and using a combo platter of JS and PHP functions on the page
to handle data as it is progressively requested/sent, but you're still doing
a round-trip each time. It only looks like a client-side solution because
you submit to the same page all the time until certain conditions are
satisfied or your user clicks on a specific link or button.
If you're truly in search of a completely client-side solution using
JavaScript, I suggest checking the Javascript Boutique or Javascript Source
or any one of the hundreds of JS repositories you'll find in a google
search. There are many great examples of this problem such as selecting a
State in one select box then having the major cities in that State show up
in a second select object.
Hope this helped.

RE: [PHP-DB] how to reuse DB results
Off the top of my head, you could do the db call once, assign the full result set to an array, pull off the parts you want at the top of the page, then use reset($arrayname) to put the pointer back to the beginning of the array then use a loop to print out the whole thing at the bottom of the page. That's just one way though. There are probably others available with and without the use of a db abstraction class.

RE: [PHP-DB] how to reuse DB results
Yeah, that's kind of what I was thinking. The logic in your pseudocode seems
correct. However, I'm not sure about the bit where you do:
$resultset[] = $results
Not because it's wrong, just because I always have to refer back to some
form of documentation when putting result sets into an array to make sure
I'm doing it right because PHP has that whole Resource thingy (I can see you
all cringing now) that represents result sets. Seems to me there's a little
more to it than what's written out above. But I'm certain it's possible to
put a result set right into an array. And once you have that, you can echo()
out whatever members of the array you want and the reset() function will
reset the array pointer to the beginning allowing you to loop through the
array and echo out the results.
Give it a go though, this can't be too far off.

RE: [PHP-DB] Version Upgrade
The folks at PHP.NET have an excellent resource to help answer questions like these. Check out this link: http://www.php.net/releases.php#4.3.0 You're going to have to read the material and compare it against what you're doing in your scripts to see if the 4.3.0 release is going to do anything to your code.

RE: [PHP-DB] Inventory Management for ecommerce store
I have an e-commerce project coming up in the next quarter and I want to just piggyback (not hijack the thread) one question onto this thread. And that is, don't e-commerce packages come with the functionality to track inventory? I mean, most times when I shop online, I see whether an item is in stock or how many pieces a retailer has in stock. I am concerned that there is more work than meets the eye with an e-commerce implementation in regards to constructing a DBMS to handle the inventory issues in addition to implementing the shopping cart and the catalog. Sorry if this is off topic, but this issue just raised a red flag for me and I need to understand it a bit better before I put together an estimate. I have a catalog component and a credit card processing component at my disposal, but need to know if it is common practice to hand-build the inventory management end of it. Consequently, this could help with Aaron's original question if there are inventory management components out there already by allowing him (and I) to simply use an existing one rather than reinventing the wheel, so to speak.
