note 114978 added to function.end

I found that the function end() is the best for finding extensions on file name. This function cleans backslashes and takes the extension of a file. <?php private function extension($str){ $str=implode("",explode("\\",$str)); $str=explode(".",$str); $str=strtolower(end($str)); return $str; } // EXAMPLE: $file='name-Of_soMe.File.txt'; echo extension($file); // txt ?> Very simple. ---- Server IP: 72.52.91.14 Probable Submitter: 95.85.174.65 ---- Manual Page -- http://php.net/manual/en/function.end.php Edit -- https://master.php.net/note/edit/114978 Del: integrated -- https://master.php.net/note/delete/114978/integrated Del: useless -- https://master.php.net/note/delete/114978/useless Del: bad code -- https://master.php.net/note/delete/114978/bad+code Del: spam -- https://master.php.net/note/delete/114978/spam Del: non-english -- https://master.php.net/note/delete/114978/non-english Del: in docs -- https://master.php.net/note/delete/114978/in+docs Del: other reasons-- https://master.php.net/note/delete/114978 Reject -- https://master.php.net/note/reject/114978 Search -- https://master.php.net/manage/user-notes.php
