Note Submitter: php at php-universe dot com ---- While recently working on a file upload script, that works on moving files and resizing images based upon their extension, I found a great way to determine the file extension. <? function get_extension($filename) {//start get_extension function return (count($tmp = explode('.',basename($filename)))>1)?array_pop($tmp):''; }//end get_extension function /* An example use of this function:*/ foreach($_FILES as $files) {//foreach $_FILES action if($files['error']==0) {//if the file was successfully uploaded $ext = "<br />.".get_extension($files['name']); echo $ext; }//end of successfull upload check }//end foreach $_FILES ?> This returns the file extension for each of the files uploaded, giving something like: .jpg .swf
