Oh, OK, that's what you meant about the 5 functions. I am not sure of the advantage to that, actually something I've always wondered. Especially if I am serializing the data anyway -- the way I see it is as follows (we are in the realm of theorizing here): Serializing is serializing, likely just as fast whether using the built-in session mechanism or a replacement, or even serializing it myself, I'm sure it all goes through the same underlying routine. Writing and reading a single flat data record like this through MySQL has to be slower than using a flat file, unless PHP flat file access is somehow drastically slower than it should be. Ergo, I'm likely to lose, not gain, by using MySQL. (So why did I ask the original question? Because I hadn't analyzed it this carefully first!) It's literally an hour's work to alter the code to use MySQL to store the sessions instead of the hard drive. This might or might not improve performance. As mentioned above -- under what circumstances would it improve? Perhaps if file open is an expensive operation and the database is already open. But it's hard to think of where one would expect the SQL access to be faster. It's incredibly UNLIKELY that trying to send an SQL query for every single line of code that currently does $_SESSION[...] = ...; is going to be faster... I'd almost be willing to say IMPOSSIBLE that would be faster, but somebody would post a trivial example to prove me wrong :-) Totally agree. But you'd probably find it easier to write a C extension and re-compile PHP to pre-load all the stuff. None of which applies to you, I don't think, but you may want to re-read that thread.

[PHP] Re: [PHP-DEV] toString() in SimpleXML?
Hi Marcus, Marcus Boerger wrote: having a function __toString() would interfere with the mapping ideas of SimpleXML. However it is there internally so you simply do one of the following: php -r '$x=SimpleXML_load_string(?xml version=\1.0\?rootblablabla/root); echo $x, \n; var_dump((string)$x);' I'm aware of that. But how would something like nodeValue() interfere with the mapping ideas behind SimpleXML? IMHO, casts are not intuitive in a development process, especially not when you need them as much as you would in SimpleXML. Now it just feels like working around a problem when coding. further questions please to [EMAIL PROTECTED] as you wish..

[PHP] Crawlers (was parsing large files - PHP or Perl)
Hi there Just an update. We altered our code last night and the result is that we have managed to bring in everything with no problem now. The slowest part was actually pulling down the emails which are on another server. I'd like to thank everyone for their help I have another project I'm working on - more as a hobby than anything else. I need to create a crawler that will crawl approximately 100,000 domains, pull in the information and then classify the content based on some logic (still to be decided but thinking of using bayesian filters). Is there anyone on this list who has written fast and decent crawlers in PHP who would be willing to share their experiences?

[PHP] Problem connecting to MySQL with PEAR::DB and mysqli
hello
when connecting to MySQL 4.1 using PHP 5 and PEAR::DB I get this error:
DB Error: connect failed
a closer look gets this:
Can't connect to local MySQL server through socket 'localhost' (2)
the code for the connection is like this::
public static function getConnection() {
$mysql_user = myname;
$mysql_password = secret;
$mysql_host = localhost;
$db_name = mydb;
$dsn = mysqli://$mysql_user:[EMAIL PROTECTED]/$db_name;
echo $dsn;
$db = DB::connect($dsn);
if(DB::isError($db)) {
echo $db-getMessage();
}
return $db;
}
===
the DSN looks correct:
and in the php.ini I set the following option:
mysqli.default_socket = /var/lib/mysql/mysql.sock
this is where the socket for mysql access is.
then I restarted apache and mysqld.
the MySQL Server is running. I can connect via mysql on the command line
but not with PEAR::DB.
I am using PHP 5, the latest PEAR::DB, Apache 1.3 on a Redhat 7.3 System.
any ideas what's wrong here ?

[PHP] map internal extension name to actual file
Hi, Does anyone have any good ideas of how to find out what extension was loaded/enabled from what actual file. For example the ming extension (thats its internal name) could come from php_ming.dll in my extensions dir. But if the file name is say mingFlash.dll how can i determine (in php) that my ming functions come from the mingFlash.dll file? I had thoughts of getting the name of the first function from get_extension_funcs(ming) and then seeing if the text of the function name appeared in the actual content of mingFlash.dll, but it seems a bit inaccurate and slow. Can unpack help me here? To re-cap id love to be able to say (from within php), yea the ming extension was loaded by enabling the mingFlash.dll in php.ini.

Re: [PHP] Dynamic/runtime object creation
Hello Joe, If you are careful, you can build a string of PHP and eval() it to create a new class definition. I've done this before, but it was for the novelty more than needed to actually use it. I know for a fact that I have seen several projects for this on the web; However, I tried doing a quick search and I was unable to find anything. Figures. do: Anyways, yes it is possible and people have done it before, but if I were going down this path I would second guess myself as to if this was the best solution. You should be able to get by with something simpler (and less time consuming to develop and test).

have you tried setting a handler function for the SoapServer,
before calling SoapServer::handle() ?:
function test($v) { var_dump($v); }
$server-addFunction(test);
if you do that do you get any output? if not then I'm really no more help to
you... you next best bet is to dive into CVS and check the test scripts (if
there are any),
unpublished documentation/examples (if there are any) and the source code (if
it means
anything to you.)
if all that fails you might consider going higher up the PHP foodchain
and mailing the maintainer/list politely asking whether there maybe a problem -
if you
do decide to mail the maintainer or internals or something - be polite,
apologetic, consise
and make sure you detail your problem fully - they are all busy people and you
want to
maximise the chance of getting a useful reply :-).

Is there other ways to do this? What if the usertable has more than these 2 columns. Thanks -Will -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Crontab for Windows
Hi, I am trying to schedule the running of some PHP scripts on my Win2K PC at home. On my live server I use Linux, so am fully familiar with Crontab. I am not that familiar with running scripts using the scheduler in Win2K though. So far what I have is: C:\php\php.exe -q c:\path\to\php\file.php But this doesn't seem to do anything..the task manager in the windows scheduler just keeps saying that the task has not been run. Any suggestions? Also, one thing I would like my script to do is to send out an email, but I don't have a mail server set up on my home PC..is there anyway to run a script from a server on a different machine, using Windows scheduler, and if so, what form would the 'path' to the file/server take?

[PHP] mail, CRLF, RFCs, MTAs, Windows and Unix [long]
I dont know if it's the right place to post, but anyway... (Sorry for the cross-post.) I think the doc for the mail function [1] should be improved, after reading bug 15841 [2], mail.c [3], skim some RFCs, and after I had different problems with PHP mail() Basicaly, the doc says to use - \n in body - \r\n in extra headers As far as I understand the matter: - SMTP requires \r\n : cfr RFCs (ex 822, 2822) - Under windows, PHP mail directly uses socket and SMTP - Under *nix, PHP mail uses \n to send subject, to, etc [3] to the sendmail/postfix/qmail binary (ok, *nix eol is \n), then the MTA uses translate this to SMTP with \r\n (adding \r to standalone \n if needed) -- ok, RFC want \r\n Which basicaly means - Under windows (SMTP, so \r\n) use \r\n for body (doc says \n) : doc KO use \r\n for mail headers (doc says \r\n) : doc ok - Under *nix (local sendmail and eol, so \n, not SMTP) use \n for body (doc says \n) : doc ok use \n for mail headers (doc says \r\n) : doc KO So, the doc is sometimes correct, sometimes not, and it leads to problems (portability, ignored headers, etc). I think correct behaviour is - windows (direct SMTP): use \r\n for headers and body - *nix (local eol, then SMTP): use \n for headers and body At least, it seems Postfix works that way, perhaps Qmail too (I dont know for other MTAs) My question is twofold (three?) 1. Am I right about that 'correct behaviour' or do I miss something? 2. If I am, could the doc be improved and explain that? Ex doc says Some poor quality Unix mail transfer agents replace LF by CRLF but \n is unix end of line, PHP src code use \n itself [3], and MTA must speak SMTP and use \r\n, so conversion seems required. -- I guess 3 is not a very good idea 3. use \n everywhere, php will automagically s#\n#\r\n# on windows only. this would add portability between *nix and windows Christophe PS Below is an example of problem I had. If I follow current mail() doc on my Linux server, ie using \n for body (ok) and \r\n for headers (ko), something like this will fail: $headers = From: [EMAIL PROTECTED]: [EMAIL PROTECTED]; $body = Hello\nWorld; Postfix (which uses \n for local *nix delivery [4]) generates headers with \n for standard headers and \r\n for extra headers, which break RFCs and cause many mail clients to see part of the headers as part of the body (really ugly): To: [EMAIL PROTECTED] Subject: foo bar\n From: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] X-Mailer: efg\r\n Which some mail clients (thunderbird and others) see as To: [EMAIL PROTECTED] Subject: foo bar\r\n From: [EMAIL PROTECTED]-- headers break here Cc: [EMAIL PROTECTED] X-Mailer: efg\r\r\n [1] PHP manual : mail() http://www.php.net/manual/en/function.mail.php [2] PHP Bug 15841 http://bugs.php.net/bug.php?id=15841 [3] PHP src : mail.c http://cvs.php.net/php-src/ext/standard/mail.c [4] Subject: Re: CRLF vs. LF (From: Wietse Venema) http://archives.neohapsis.com/archives/postfix/2000-02/0398.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I use nncronlite which is a cron implementation for windoz (familiar crot.tab file); http://www.batchconverter.com/nnCronLITE-download-16062.shtml One problem I encountered with the MS scheduler, is it needed to be running as a process, and in an implementation of windows that had Microsoft SQL Server running on NT, seems this SQL server has the ability to schedule some batch processes, but it implemented a replacement for the batch scheduler that would not process my AT commands.

Re: [PHP] traversing multi-dimensional arrays
Forget about the $cars array. The array key in the $models array will
be your car list.
$cars=array(ford,chevy);
$models=array(ford=array(ranger,escape),chevy=array(malibu,
tahoe));
//Loop through first level of array, getting car maker
foreach($models as $carmaker=$models) {
//Loop through car models, paring up with maker
foreach($models as $model) {
echo $carmaker.'-'.$model.'br /';
}
}
Another option, which isn't as readable, is to use implode instead of
the inner loop.
$cars=array(ford,chevy);
$models=array(ford=array(ranger,escape),chevy=array(malibu,
tahoe));
foreach($models as $car=$models) {
$pairing = $car.'-'.implode('br /'.$car.'-',$models).'br /';
echo $pairing;
}

Re: [PHP] Password Protection] -- My solution

Here is the setup that I have used.
Please, adapt to your needs.
Table 'theTable' is supposed to contain columns fname, mname, lname
and ePass (encrypted password). The crypt() function produces a password
that
cannot be decrypted and really works well.
Of course, you need to use crypt() in the PHP script that creates a row in
'theTable'.
?php
#-- code starts here
-#
$action = $_POST[action];
if( !empty( $action ) )
{
$userName = $_POST[userName];
$passw= $_POST[passw];
# Bring the encrypted password and creation date from database:
$cmd = SELECT * FROM theTable
. WHERE userName='$userName' ;
$res = mysql_query( $cmd ) or die( Password search failed. );
$numRows = mysql_num_rows( $res );
if( $numRows == 0 )
{
print( $userName not a valid user name.BR );
exit;
}
$rec = mysql_fetch_array( $res );
$privLevel = $rec[level];
$nome = $rec[fname]. .$rec[mname]. .$rec[lname];
# Encrypt the password:
$passe = crypt( $passw, $rec[ePass] );
if( $passe == $rec[ePass] )
{
/* Bring up the home page */
print( h2WELCOME TO MY HOME PAGE/h2 );
exit;
}
else

If you know what manufacturer you want ('ford' or 'chevy') then you can
just get the models for that by doing this:
$car = 'ford';
foreach($models[$car] as $key = $model) {
print The car is a $car $model;

It's kind of a Good Idea to store the password encrypted using MySQL's md5() function or other similar functions. In the old days, you'd use their password() function so you still see that a lot, but it's deprecated, as they want to be able to change the guts under-pinning their password() function that they use internally, since various encryption algorithms become obsolete. The point being that if somebody breaks into the database, they don't see any actual passwords, just a bunch of useless junk -- But *YOU* can call the md5() function on a password and compare the result to what's there. md5 and similar functions are what you call a one-way encryption -- There's no (easy) way to take the output and go backwards to the input.

If you have two *ROWS* with the same username, then you have the same user in there twice, which is BAD or two people using the same username which is REAL BAD.

it's the DSN itself that is messed up...
Assuming that DSN means the same thing in 'DB' as it does in 'ODBC', which
may be a completely invalid assumption on my part...
Perhaps try changing 'localhost' to '127.0.0.1' in case your DNS and
/etc/hosts are messed up somehow.
I suppose you could even try changing localhost to
'/var/lib/mysql/mysql.sock' -- not that I think it will work, but it's the

For example, md5('foo') today, will be equal to md5('foo') tomorrow.

[PHP] Re: map internal extension name to actual file
Zac Barton wrote: Hi, Does anyone have any good ideas of how to find out what extension was loaded/enabled from what actual file. For example the ming extension (thats its internal name) could come from php_ming.dll in my extensions dir. But if the file name is say mingFlash.dll how can i determine (in php) that my ming functions come from the mingFlash.dll file? I had thoughts of getting the name of the first function from get_extension_funcs(ming) and then seeing if the text of the function name appeared in the actual content of mingFlash.dll, but it seems a bit inaccurate and slow. Can unpack help me here? To re-cap id love to be able to say (from within php), yea the ming extension was loaded by enabling the mingFlash.dll in php.ini.

Oh, OK, that's what you meant about the 5 functions. I am not sure of the advantage to that, actually something I've always wondered. Especially if I am serializing the data anyway -- the way I see it is as follows (we are in the realm of theorizing here): Serializing is serializing, likely just as fast whether using the built-in session mechanism or a replacement, or even serializing it myself, I'm sure it all goes through the same underlying routine. Writing and reading a single flat data record like this through MySQL has to be slower than using a flat file, unless PHP flat file access is somehow drastically slower than it should be. Ergo, I'm likely to lose, not gain, by using MySQL. (So why did I ask the original question? Because I hadn't analyzed it this carefully first!) Except that your MySQL buffers and caches may well be larger than, or under-utilized when compared to, your already over-stressed file buffer in the Operating System. Sure the data all ends up being written by MySQL sooner or later, and there's definitely more overhead with MySQL than with the file OS system. *BUT* there are simply too many variables in buffers, caches, and OS utilization for you to predict what's faster. It's literally an hour's work to alter the code to use MySQL to store the sessions instead of the hard drive. This might or might not improve performance. As mentioned above -- under what circumstances would it improve? When the file system is already getting hammered, but MySQL is under-utilized for the amount of RAM/cache/buffer space you've given it. And we can safely assume MySQL has the file already opened up and ready after your first request, so the file open, which *IS* expensive, will not be there. But you've got the MySQL overhead that is inherent to a connection. But... We could play this theoretical game all day. Or you could spend an hour and TEST IT.

[PHP] Date() reporting wrong on OS X server intermittently

Re: [PHP] [HAB] PHP or ASP.Net
I find it humorous that these types of debates keep coming back up -- no matter what the topic, the IT world can not seem to agree on anything. OS wars - Browser wars - coding languages. It all gets very tiring. Bottom line - go with what you like and with what can get the job done. Myself personally, I have never found something that I could not do in PHP. However, that being said, a lot of companies simply do not want to leave off the Microsoft model. So if you want to work for those companies you will need to know ASP.

AFAIK crc32() is the fastest hashing function in PHP. I don't have

auto-generates hashes for each file in a directory. crc32() was faster
than md5() and sha1().

The formula to calculate the measurements varies from line to line, so I need to have 16 standard formulas like: TopMeasurment+1.6875+OutOfPlumbWall The TopMeasurement and OutOfPlumbWall are decimal numbers entered in a separate screen (from the measurers information) and will be stored in a table. The 1.6875 can vary from job to job. I need to give the people doing the entry the flexibility to change the formula. This is a simple example and only has one variable (though mostly it is static). Other formulas have 10 and 12 variables in them. How have others gone about storing formulas that require such modifications?

You probably have a missing ' or somewhere BEFORE line 52.
And probably in the stuff you chopped out, since others ran the code you

If I was programming this I would probably create 16 functions for
whatever the formula is supposed to produce. If you believe that a
constant will usually work you can have that as a default.
?php
define('TABLE_STANDARD_ERROR', 1.6875);
function table_get_length($top, $plumb, $se = null) {
if (null === $se) {
$se = TABLE_STANDARD_ERROR;
}
return $top + $se + $plumb;
}
/** Now the fun begins... assume that $_POST is populated with data and
it has been scrubbed for improper input... */
$length = table_get_length($_POST['top'], $_POST['plumb'], $_POST['se']);
echo In order to make the table, you need $length inches of wood.\n

Is it possible to make a function that would increase/decrease a
counter which would contain the page number that they were on? I am
not sure about doing all this, since I am a bit new, but I believe
that's what I'd investigate.
$pagenumber = thepagenumberthatweareon
int getNextPage(int currentPage, int scale), where scale 'up' or 'down'
function getNextPage($currentPage, $scale) {
global $pagenumber;
if ($scale = 'up') {
return $currentpage + 1;
} else {
return $currentpage - 1;
}
}
That could be a totally bogus function, but I thought it'd be fun to
throw that out. It at least gives you something to go on, I guess.
As long as we're looking at this, anyone want to suggest to me if I had
done anything wrong with that function, and how I can improve on it?
Thanks

Re: [PHP] mysql query
Now I am assuming that 4 and 6 would not always be the next article ID -
otherwise you could just increment your id accordingly.
If you wanted to do that without running multiple queries, this is who I
might do it, rather sloppy, but I think it would work.
$idGet= $_GET['id'];
$sql = select id, title from articles;
$db-query($sql);
$i=0;
while($db-getRow()) {
$id[$i] = $db-row['id'];
$title[$i] = $db-row['title'];
$i++;
if($id[$i] == $idGet) {
$j = $I;
}
}
$prev = $j-1;
$next = $j+1;
previous $title[$prev ]
next $title[$next]

[PHP] Problem: mysqli class not found
I have an install of PHP 5 on Windows 2003 Server with Apache 2 and when I reference mysqli in my php code, I get an error that the mysqli class is not found. I looked at the php.ini file and I added a line for php_mysqli in the extensions section and I edited the extension_dir directive to point to c:\php\ext folder (I used /php/ext as the value assigned to the directive. I made sure that the c:\php\ext folder actually had a file called php_mysqli.dll, which it did. No I can't start my Apache server. I had done a default install of both Apache 2 and PHP 5. Any ideas as to how I can get the mysqli class identified and allow my Apache server to start.

AFAIK crc32() is the fastest hashing function in PHP. I don't have
actual results on hand still, but I created a filesystem plugin that
auto-generates hashes for each file in a directory. crc32() was faster
than md5() and sha1().
FYI the benchmarking that I did was for a Windows XP system... YMMV
I normally profile with apd, but it only measures in the hundredth of
a second.
So I used getrusage() memory_get_usage() functions to *unscientifically*
profile md5()/sha1()/crc32() on FreeBSD 5.3.
I ran a for loop 75 times, hashing the constant __FILE__
These are an average of 5 runs -
md5:
Usertime - 784.2 µsec
Systemtime - 72.2 µsec
Memory - 120.0 bytes
sha1:
Usertime - 846.8 µsec
Systemtime - 150.2 µsec
Memory - 80.0 bytes
crc32:
Usertime - 194.8 µsec
Systemtime - 54.2 µsec
Memory - 80.0 bytes
Can you shed some light on that code,
that you're using for the filesystem plugin?
