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
Full path command also not working .
i have centos6.5 with php5.5 installed on my vps too .
and Windows7 with php5.5 on my localhost
