note 107768 added to regexp.reference.delimiters

When you use meta-characters in the regular expression, avoid using them as delimiters. In preference, do not use the meta-characters as delimiters at all. Besides, you must not forget to escape the delimiter if it exists in the user text. The function preg_quote permits to escape the delimiter if it exists in the user text. <?php $usertext=preg_quote($usertext,$delimiter); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 41.227.178.172 ---- Manual Page -- http://www.php.net/manual/en/regexp.reference.delimiters.php Edit -- https://master.php.net/note/edit/107768 Del: integrated -- https://master.php.net/note/delete/107768/integrated Del: useless -- https://master.php.net/note/delete/107768/useless Del: bad code -- https://master.php.net/note/delete/107768/bad+code Del: spam -- https://master.php.net/note/delete/107768/spam Del: non-english -- https://master.php.net/note/delete/107768/non-english Del: in docs -- https://master.php.net/note/delete/107768/in+docs Del: other reasons-- https://master.php.net/note/delete/107768 Reject -- https://master.php.net/note/reject/107768 Search -- https://master.php.net/manage/user-notes.php
