<?php protected function is_uri_friendly($uri)
{
$uri = "game/counter-strike/league/test";
        if (preg_match('#[^a-z0-9/-_]#i', $uri) > 0) {
                echo "$uri contain invalid characters\n"; 
        }else {
                echo "$uri DOES NOT contain invalid characters.\n";
        }

?>
}

it's because the /-_ part of your negative char class is being interpreted as a range of chars between / and _ you need to either escape the hyphen or put it at the beginning or end of the list.
