    I want to extract numbers from an array, the array is an url. The url is for instance www.hostname.com/dir/47.php or /dir/1324.php and so on. The code I made works fine by doing this, but I'm no PHP wizkid.

    Is there a more easy way to extract the numbers from the url?

    Here is the code I made:
    <?
$dir = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$link = eregi_replace("www.hostname.com/dir/", "", $dir);
$no = eregi_replace(".php", "", $link);
require_once("http://www.hostname.com/dir/index.php?c=$no");
?>
    Code (markup):

    I'd do this..
    
$no = substr(basename($_SERVER['PHP_SELF']),0,-4);
require_once("http://www.hostname.com/dir/index.php?c=$no");
