vb.org Archive - PHP 5.3 issue?

I utilize bit of code I found on here that allows for rotating banners on my website.

It works just fine under PHP 5.2.9, unfortunately, when I upgraded to 5.3.0, it broke.

I have absolutely zero experience with PHP coding, but since the snippet is pretty small, I was hoping one of the experts could perchance take a look and resolve it for me.

The code is called via my header template in this manner:

Code:

 <td class="header" align="$stylevar[left]" nowrap="nowrap"><a href="$vboptions[homeurl]/?$session[sessionurl]"><img src="images/armada/header1.gif" alt="" border="0" /><img src="images/armada/header/header.php?" alt="" border="0" /></a>

HEADER.PHP contains:

Code:

<?php

// DEFINE ACTUAL PATH TO IMAGE DATA FOLDER

        $folder = ".";

        if (substr($folder,-1) != '/') { $folder = $folder.'/'; }



// DEFINE VALID EXTENSIONS AND CONTENT TYPES

        $extList = array();

        $extList['png'] = 'image/png';

        $extList['gif'] = 'image/gif';

        $extList['jpg'] = 'image/jpg';



// RETRIEVE VARIABLE DATA FROM THE QUERY

        if (isset($_GET['fid'])) { $fid = $_GET['fid']; }

        if (isset($_GET['pid'])) { $pid = $_GET['pid']; }



// VALIDATE CURRENT IMAGE DATA, CHECK FID, CHECK PID

        if (!file_exists($img) && $fid > 0) { $img = $folder . $fid . ".png"; }

        if (!file_exists($img) && $pid > 0) { $img = $folder . $pid . ".png"; }



// VALIDATE CURRENT IMAGE DATA, RANDOMIZE

        if (!file_exists($img)) {

                $fileList = array();

                $handle = opendir($folder);

                while (false != ($file = readdir($handle))) {

                        $fileInfo = pathinfo($file);

                        if (isset($extList[strtolower($fileInfo['extension'])])) {

                                $fileList[] = $file;

                        }

                }

                closedir($handle);

                if (count($fileList) > 0) {

                        $imageNumber = time() % count($fileList);

                        $img = $folder.$fileList[$imageNumber];

                }

        }



// POST CURRENT IMAGE DATA TO QUERY FETCH

        $imageInfo = pathinfo($img);

        $contentType = 'Content-type: '.$extList[$imageInfo['extension']];

        header ($contentType);

        readfile($img);

?>

I truly hope someone out there can point out where the problem lies.

Thank you very much for your time.
