So I have this code and I’m only trying to make a list of the saves in another directory where the php scrip is in xampp folder and the saves are to this path /root/files/saves:
JavaScript
x
<html><body><?php$output = shell_exec('ls /root/files/saves');echo "<pre>$output</pre>";?></body></html>I don’t know why I can’t get it working on a var_dump it seems output is null I’m really confuse it should work or I just it all wrong I need some help.

Answer
Add 2>&1 to the end of your shell command to have STDERR returned as well as STDOUT.
JavaScript
$output = shell_exec("ls /root/files/saves 2>&1");Also, if the user running PHP doesn’t have sufficient permissions to view the output in /root/, the above code will return a Permission denied error message.
