note 54804 added to reserved.variables

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 ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54804 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54804&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54804&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54804&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54804&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54804&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54804&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54804&report=yes Search -- http://master.php.net/manage/user-notes.php
