So, if God begat Rasmus, and Rasmus begat PHP... that means PHP is like a
gift from God right? Kinda like the Transformers? And microwave burritos?

That sound like the lineage to me. (Don't you hear the voices?)

Hi, I'm using SWFUpload JavaScript for my upload in my logged part of
website. I'm passing session_id in every post request from flash
object. In my script I set forwarded id with
session_id($_POST['passed_id']) but I got logout on that request (it's
redirecting me to login page) and I'm also logged out in my browser
(not flash). Then I need to relog. Everything is working fine when I'm
not touching session_id() id setting. Any clues?

Try this instead:
<?
session_start();
$_SESSION['passed_id'] = $_POST['passed_id']; // Sets the server-side
session variable
$_COOKIE['PHPSESSID'] = $_POST['passed_id']; // Names the session
whatever data was POST'ed
?>
As always, BE SURE TO SANITIZE YOUR CODE!

It depends on the size and scope of your project. For the most part, you
should know what you have coded before and when encountering something new, the
previous work should help in doing the new work.

Subject: [PHP] When to use design patterns?
Hi all,
Design patterns are really hot today.
And I am really interested when and how often they are used.
It is said that 99% of the projects don't need them.
Any opinion appreciated.

Or make a 'truncate.sql' file with the tables in it to truncate:
TRUNCATE TABLE foo;
TRUNCATE TABLE bar;
Then in the crontab "mysql mydatabase < truncate.sql"
No PHP needed.

Yeah, I should have mentioned that...
PHP 5.1.6, MySQL 5.0.48 (client and server I think; I'm not the sysadmin).

I'll have to ask our sysadmin for the test scripts he ran. (We're running the
site on Drupal, which can handle either, but has a lot of DB abstraction
involved. He tested it sans-Drupal, but I am not sure what his scripts
were.)

I am building a report application that generates some text files for
download and when the download starts it stops prematurely.
The file sizes are currently in the order of the mega bytes and when I
try the script that generates and sends the file in a test server the
process goes smoothly no matter the size of the file but as soon as I
move the script to the production server dowloads cut at 300kb aprox.
My current workarround is to gzip the files and that is giving me some
extra time but the files are growing and sooner or later my
workarround will become useless.
I guess the download is stoped by some timeout and not because of the
amount of kb downloaded because the size varies slightly. If that
timeout exists it should be of apox. 5-10 seconds.
I use this function to perform the upload $contenido is the content of
the file and to that variable I assign the big chunk of output from
the report, $nombre_archivo is the optional name for the file. I can
paste more code but I think the problem is here.
<?php
function enviarArchivo($contenido, $nombre_archivo = "") {
if($nombre_archivo == "") {
$nombre_archivo = date("dmyHi").".csv";
}
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=$nombre_archivo");
header("Content-Length: ".strlen($contenido));
echo $contenido;
}
?>
Thanks in advance

Though this is not likely to solve the problem, try adding the following two
lines at the beginning of the script (even before you query the database and do
all your logic)
ignore_user_abort(true);
set_time_limit(0);
If this solves the problem you should read this http://ar2.php.net/info and this
http://ar2.php.net/manual/es/function.ignore-user-abort.php carefully and then
choose more rational settings. PHP has a default execution time of 30s.
However, this is not likely to solve the problem as execution time should not be
affected by streaming and we are assuming the user/browser is not aborting the
connection. On the other hand you could support download resuming (it involves
some tricky headers and if you are willing to dig deeper into this read the
manual notes at http://ar.php.net/manual/es/function.header.php). But this won't
solve your problem... at least for IE as it doesn't support resuming :(.
You need the log files to know exactly what the problem is. And, even if you are
not solving this issue using compression as a workaround, you may also want to
add at the beginning of the script:
ob_start("ob_gzhandler")
Or... you can use "zlib.output_compression" INI setting in an .htaccess file or
in php.ini.
Compressed files will require more server processing but will download way
faster. ob_gzhandler and zlib compression are transparent to the end user, so
they will think they've got the uncompressed file, no need to gzip the files
programmatically.
