Hey, say I have a url just being passed through my php is there any easy way to get some GET variables that are being passed through it? It\'s not the actual url of the page

Answer 1

$href = 'http://www.somesite.com/index.php?url=var&file_id=var&test=var';

$url = parse_url($href);
print_r($url);
/* Array
(
    [scheme] => http
    [host] => www.somesite.com
    [path] => /index.php
    [query] => url=var&file_id=var&test=var
) */

$query = array();
parse_str($url['query'], $query);

print_r($query);
/* Array
(
    [url] => var
    [file_id] => var
    [test] => var
) */
