This way, when they change, the link will change and the browser will reload the sitemap… Otherwise it will be fine to be cached as it wont have changed.

Personally, I would explode on the ‘/’, then on the ‘.’, etc…

//PATH INFO RETURNS: DIRNAME, BASENAME, EXTENSION, FILENAME FROM A PATH
$details = pathinfo('videos/file.flv');

//EXTRACT EXTENSION FROM THE DETAILS ARRAY CREATED BY PATH INFO
$extension = $details['extension'];

//PRINT THE EXTENSION OF THE FILE
echo($extension);

    $output .= "</body>";
    $output .= "</table>";
    return $output;

Use like this:
echo dumpr(‘NAME’,$var);
echo dumpr(‘SESSION’,$_SESSION);
etc..

Displays a nicely formatted table, with values of a string / array / object clearly displayed.
