I think that you are looking for shell_exec

shell_exec("/path/to");

edit: sometimes the problem is with escaping, wrap your arguments with escapeshellarg

Problem could be related with incorrect path or permission settings on Linux.

You can test this function in a php script to show the content of a folder:

<?php
    $output = shell_exec('ls -lart 2>&1');
    echo "<pre>$output</pre>";
?>

Notice this function is disabled when PHP is running in safe mode.

`string(44) "sh: ipconfig/all: No such file or directory " ` showing this error – Rejoanul Alam Aug 05 '15 at 08:48
If you are on linux the command "ipconfig/all" doesn't work it is "ifconfig" instead ! You can do a man ifconfig for further information. – Sunitrams Aug 05 '15 at 08:51

I have root access. How can I enable this function? – Rejoanul Alam Aug 05 '15 at 09:06
Go to php.ini configuration and search with keyword "disable_functions". You might see disable_functions=exec,system,passthru,.. Remove the required names from this. – ManiMuthuPandi Aug 05 '15 at 09:40
