This should work for you:

<?php

       $url = "http://localhost/sports/soccer/page_id/776543233242";
       $part = basename($url);

       if(strlen($part) == 11 && $part[0] == 8 || strlen($part) == 12 && $part[0] == 7)
            echo "yes";
        else
            echo "no";

?>

Output:

yes
