Using Shell_exec in Plesk

[Jamai]

I noticed that I cannot use shell_exec in Plesk because safe_mode is on. When I turn it off, it works.

My script looks like this:

<?
echo shell_exec('uptime');
?>

When I add

ini_set("safe_mode",0);

It just won't work

I also tried it using /home/httpd/vhosts/mydomain.com/conf/vhost.conf:

<Directory "/home/httpd/vhosts/mydomain.com/httpdocs">
php_admin_flag safe_mode off
php_admin_value safe_mode 0
</Directory>

This also won't work, I restarted Apache but no changes. I don't want to change this setting for the complete webserver, only for this domain.

Does anyone know how I can do this?
