note 58940 added to index

I have noticed that PHP doesn't have a function or construct for getting the file extension. I made a very simple function to settle that problem. <? function get_ext ($filename) { $dismantle = explode(".", $filename); $segments = count($dismantle); $ext = $dismantle[$segments-1]; return (empty($ext) ? 'invalid' : $ext); } //USAGE : get_ext ( str filename) echo get_ext('aktar.php'); ?> NOTE : if you use this function as is then you should be aware that an invalid file extension will return the word 'invalid' ---- Manual Page -- http://www.php.net/manual/en/index.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58940 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58940&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58940&report=yes Search -- http://master.php.net/manage/user-notes.php
