PHP File extension case changer

/ Published in: PHP

Small script to rename files in a given directory so that their extension is lowercase (i.e. example.JPEG becomes example.jpeg). Useful for keeping extensions consistent before uploading to a server with a case sensitive file system.

Note this includes code specifically for PHP on Windows (merely because it was written for use on my local XP machine) which remove the XP-created "Thumbs.db" files. On OS X, the equivalent is .DS_STORE. I don't now about Linux (it probably differs depending on the distribution??).

<?php
$root = $_GET['root'];
$files = array_merge(glob("$root*.*"),glob("$root*\*.*"),glob("$root*\*\*.*"));
$z=0;
for($i=0;$i<count($files);$i++) {
	if(stripos($files[$i],"Thumbs.db")) {
		unlink($files[$i]);
		$z++;
	}
	else {
		rename($files[$i],strtolower($files[$i]));
	}
}
echo "$i files renamed. $z Thumbs.db files deleted.";
?>
