PHP exec,system,shell_exec not working with wget on ubuntu machine

Question

i have a simple script which im testing at the moment but it's not working.

I have this simple lines :

$url = "http://www.google.com";   
system("wget --page-requisites ".$url); 

The issue is that it does nothing, my website is located at /var/www/html/server_a which is where im checking if it downloaded the required page but seems like it's doing nothing.

Im using a VPS with Ubuntu 14.04

Your issue is sudo, you need to add sudo before you run this command.

$url = "http://www.google.com";   
system("sudo wget --page-requisites ".$url);
