regex pattern to match a url in php

Question

i need help with this regex pattern. I have tried many different patterns but none return anything. I always get an empty array. The following patterns return no results.

//test 1    
$regex = '/linkDestUrl = \'(.*)\'/';

//test 2
$regex = '@^(?:\s)*(linkDestUrl = \'(.*)\');@mi';

to match this

linkDestUrl = 'http://www.google.com';

Answer 1

if its that simple, this should work:

$search = "linkDestUrl = 'http://www.google.com';";
preg_match_all("/linkDestUrl = '(.*)';/im", $search, $result);
var_dump($result[1]);
