How to hide "system()" output?

[opt_inf_env@yahoo.com]

Hallo,

I want to see from php-file list of files which are in directory, where
is the given php-file. To do so, I put in the php-file the following
line:

<?php $sys = system("ls") ?>

Then I would like to work with string $sys. However, in the place where
the "system()" is executed, php-file print on screen result of the
execution. I would like to avoid this. Do you know how I can do it?

$sys = `ls`;

Note that the command is enclosed in backticks (`), not single
quotes (').

Also, you may want to avoid program execution calls, because
they may not be available on your hosting service. Consider
using opendir()/readdir() instead:

http://www.php.net/opendir

In this case, use opendir() and readdir() instead.

Or to answer the specific question, read the manual for system(), which points
to the related function exec(). But don't use that.
