how to disable php ouptut with system commands ?

[graziano]

Hello

I have to execute this shell_exec command on my scripts

$executeonly=shell_exec("ls /etc/vmail -L -l -t");

if "ls" finds not existent symlinks it reports a lot of errors like this

no such file or directory
no such file or directory
no such file or directory
no such file or directory

Since I want hide this output , I'm trying

ob_start();
$executeonly=shell_exec("ls /etc/vmail -L -l -t");
ob_end_clean();

but I continue to receive

no such file or directory
no such file or directory
no such file or directory
no such file or directory

How to hide this shell_exec output ?

Thanks

[man]shell_exec[/man] simply returns a string of the output. you can use [man]str_replace[/man] to strip out any unwanted data.

You can redirect the output of the ls command.

Something like...

$executeonly=shell_exec("ls /etc/vmail -L -l -t > /dev/null 2>&1");

Assuming you want to capture the non-error results, I think you might want:

$executeonly=shell_exec("ls /etc/vmail -L -l -t 2> /dev/null");

Unluckly none of these solution works ...

/bin/ls: /etc/vmail/passwd.leding.nl.e-dot.nl: No such file or directory
and so on ....

also str_replace is not useful in this case.
