So the other day someone was looking for a quick php script that would load a random image from a folder (rotating banner script) and display it on their website. There are already a ton of scripts out there that do this but of course, this was an excuse to build something for fun. So, I decided to create a script that would do just this but with the least amount of code lines still keeping it efficient (again, just for fun). This is what I came up with:
$files = @opendir($dir=trim($_REQUEST[‘dir’])) or die(‘Not Valid’);
while($file = readdir($files)) preg_match(‘/(.png)|(.gif)|(.jpg)/i’,$file) ?
$images = array($file,substr($file,strlen($file)-3)) : null;
count($images) ? header(‘Content-type: image/’.$images[$id=rand(0,count($images)-1)]) :
