I tend to use one of a programms that i installed on my vps server ,

the script which i made is work perfectly on my localhost , but it doesn't work on vps.

Here what i tried 

$r = shell_exec('wkhtmltopdf http://monsite.ma/generate/15 /var/www/vhosts/monsite.ma/qr-u15.pdf');
// $r contain a null variable
