system() just does nothing

[Adrian Stutz [anime_layer]]

Hello,

I try to do a mysql backup using mysqldump. I've written a php script that
uses system() to execute mysqldump. I have two unix servers and the script
runs fine on the frist one but fails without any error on the second server. I
have following script to test it:
----------------------------------
<?php
print system ('/usr/bin/mysqldump --opt -u user -ppassword database 2>
/home/user/public_html/backup/error.txt | gzip >
/home/user/public_html/backup/bck120404.sql.g z');
?>
----------------------------------
This script doesn't return anything. No error.txt and no bck120404.sql.g z are
written. It's a unix server and register_global s is off. All directories
should be fine and "print system ('ls');" runs ok. I also tried exec(),
passthru() and shell_exec().
Any idea what I'm overlooking?

Thanks,
Adrian

Try turning more error reporting levels on with the error_reporting ()
http://www.php.net/error_reporting and see if it then gives you an error.

eg error_reporting (E_ERROR | E_WARNING | E_PARSE | E_NOTICE)

Right, forgot that. Tried to set it to E_ALL and what you proposed and I still
get no error. :(

Thanks,
Adrian

Did you check if the command works if you enter it manually on the
command line?

Root or normal user?

I don't have root access to the server. Normal user.

Hmm... I just noticed that they aren't two seperate server but ony two
seperate accounts on the same server. Setup should be exactly the same (Unix,
Apache 1.3.29, PHP 4.3.3). As mentioned, the script runs fine on one account
but after I copy it to the other account and change the path and mysql
settings it won't work anymore.

Ja ne

Re: system() just does nothing

*doh* I'm stupid.
The permissions for the directory weren't set correctly. PHP runs as another
user and couldn't write to the dir. Since I was directing the error output
there it couldn't write the error.txt (bit unpractical, though).
Works fine now. Thanks to everyone for the help.

Ja ne
