Creating a random banner in php

Hi everyone, not long ago I had to create a randomly rotating banner on a website, here's the php code you need to do it!

Hi everyone, not long ago I had to create a randomly rotating banner on a website, here's the php code you need to do it!

php

<?php

if ($handle = opendir('/percorsodirectoryserver/banner/')) {

    $array=array();

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

        if($entry!='.' && $entry!='..')

            $array[]=$entry;

    }

    $imm=array_rand($array);

    closedir($handle);

    $fp = fopen("/percorsodirectoryserver/banner/".$array[$imm], 'r');

// Imposta il mime type

    header('Content-type: '.mime_content_type("/percorsodirectoryserver/banner/".$array[$imm]));

// invia il contenuto al browser

    fpassthru($fp);

    fclose($fp);

}

?>

Give it a try yourselves, then you just use the php file inside an html img tag, and you'll always get a random image loaded from the /percorsodirectoryserver/banner folder!
