Banner Rotation

[iBuddy]

Im trying to create a way for a way of several banners saved in a folder and a script to randomly select one of those images each time a page refreshes.

<img src="$banner_random">

And the $banner_random variable pulls from a folder called "banners" so say I had several banners in there labeled
"banner1.gif
banner2.gif
banner3.gif" etc

OK.whats the question??

So... pick a random number from 1 to 3:

$filenum = rand(1,3);

Then, append the number to the file name:

$filename = "banner" . $filenum . ".gif";

Now, just use $filename to grab the file.

<?php 

$dir_file = array();
$i=0;
if ($handle = opendir('./images')) {
    while (false !== ($file = readdir($handle))) { 
        if ($file != "." && $file != "..") { 
            $dir_file[$i++] = trim($file);
        } 
    }
    closedir($handle); 
}

echo '<img src="images/'.$dir_file[rand()%count($dir_file)].'" />';
