How I do this ?

By using one of the sys exec functions: http://php.net/exec

Mind that PHP likely won’t have the required permissions to run commands that modify the OS.

Why do you want to run this in PHP? Why not just a bash script? That seems perfect for this.

thank you so much for you respond but im just a beginner in PHP. and I have app Programmed on this language. but that don’t prevent me to trying The way That you suggested . could you help me ??

Did you try the example on the page Dormilich linked to?

Example #1 An exec() example

<?php
// outputs the username that owns the running php/httpd process
// (on a system with the "whoami" executable in the path)
echo exec('whoami');
?>

Please pay special attention to the Notes and Warnings on that page. This path has a lot of potentially major pitfalls and should not be taken lightly or rushed.

chmod -R 777 /root/

First you need to modify the script so that you don’t need that chmod. Its a very bad idea from a security point of view.
