(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

On this page, I am using some JavaScript to display random text stings, and a
PHP script to display random images. The images do not consistently change when
the page is refreshed, but the text strings do. This page/PHP script does
perform correctly in Opera 7.11 and IE 6.0.29

Reproducible: Always
Steps to Reproduce:
Visit the page, look at the images, hit refresh few times...very few, if any, of
the images will change.




PHP script follows
-----------------------

<?php

*/

// Make this the relative path to the images, like "../img" or "random/images/".
// If the images are in the same directory, leave it blank.
$folder = '';

// Space seperated list of extensions, you probably won't have to change this.
$exts = 'jpg jpeg png gif';

$files = array(); $i = -1; // Initialize some variables
if ('' == $folder) $folder = './';
$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
    foreach($exts as $ext) { // for each extension check the extension
        if (preg_match('/\.'.$ext.'$/i', $file, $test)) { // faster than ereg,
case insensitive
            $files[] = $file; // it's good
            ++$i;
            }
        }
    }
closedir($handle); // We're not using it anymore
mt_srand((double)microtime()*1000000); // seed for PHP < 4.2
$rand = mt_rand(0, $i); // $i was incremented as we went along

header('Location: '.$folder.$files[$rand]); // Voila!
?>
