Vil nogen hjælpe mig at omskrive dette script?

Ca. sådan:

<?php

    $mime = array("gif" => "image/gif"
        , "jpg" => "image/gif"
        , "swf" => "application/x-shockwave-flash");
    $files = glob( "*.{gif,jpg,swf}", GLOB_NOSORT );
    shuffle( $files );
    $banner = $files[0];
    $ext = substr( $banner, -3 );   
    header( "Pragma: no-cache" );
    header( "Expires: Monday 01-Jan-80 12:00:00 GMT" );
    header( "Content-Type: " . $mime[$ext] );
    readfile( $banner );
   
?>
