Regex Help

[russ7581]

I'm developing an Authorization system and I'm stuck on the regex part of it.

I have a file containing all of the places that a person is allowed to go:

global $roles;

$roles['god'] = array(
     'paths' => array(
          "/",
          "/index/helloworld/"
     )
); 

Now when the page loads I need to compare the uri to the role of the user:

foreach ($roles['god']['paths'] as $path) {
     /* compare uri to the path */
} 

That's where I get stuck, I'm not sure on how to compare both paths.
Thanks in advance for any help.
