note 89711 added to function.strlen

When dealing with submitted forms that you've imposed a character limit on, you must remember that functions that count characters consider "\r\n" to be two characters. <?php //These will both output 2. echo strlen("\r\n"); echo mb_strlen("\r\n"); ?> If I had thought of this starting out, I would have saved myself several hours of trouble trying to get php to cut a message to the same length that my auxiliary javascript validation imposed on it. ---- Server IP: 209.41.74.194 Probable Submitter: 76.16.128.198 ---- Manual Page -- http://www.php.net/manual/en/function.strlen.php Edit -- https://master.php.net/note/edit/89711 Del: integrated -- https://master.php.net/note/delete/89711/integrated Del: useless -- https://master.php.net/note/delete/89711/useless Del: bad code -- https://master.php.net/note/delete/89711/bad+code Del: spam -- https://master.php.net/note/delete/89711/spam Del: non-english -- https://master.php.net/note/delete/89711/non-english Del: in docs -- https://master.php.net/note/delete/89711/in+docs Del: other reasons-- https://master.php.net/note/delete/89711 Reject -- https://master.php.net/note/reject/89711 Search -- https://master.php.net/manage/user-notes.php
