PHP: Random banner function?

[ayu]

Hello, i was trying to do a random banner function for my site, but since i am not good at all with PHP yet, i failed =(

this is the banner code

Code: Select all

<td width="223"><img src="themes/Nice_Blue/images/logo.png" width="435" height="99" vspace="5" hspace="5"></td>

i tried doing this

Code: Select all

<?
$alllogos = array
      ("themes/nice_blue/images/logos/logo1.png", "themes/nice_blue/images/logos/logo2.png", "themes/nice_blue/images/logos/logo3.png");
    $totallogos = (count($alllogos));
    $nmbr = (rand(0, ($totallogos)));
?>


  <tr> 
    
    <td width="223"><img src="<? echo$nmbr?>" width="435" height="99" vspace="5" hspace="5"></td>

But it failed ^^ greatly, could anyone give me a hand? =P

I Googled and found this =)

Code: Select all

<?php

$folder = '';

$exts = 'jpg jpeg png gif';

$files = array(); $i = -1; 
if ('' == $folder) $folder = './';

$handle = opendir($folder);
$exts = explode(' ', $exts);
while (false !== ($file = readdir($handle))) {
    foreach($exts as $ext) { 
        if (preg_match('/\.'.$ext.'$/i', $file, $test)) { 
            $files[] = $file; 
            ++$i;
            }
        }
    }
closedir($handle); 
mt_srand((double)microtime()*1000000); 
$rand = mt_rand(0, $i); 

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