note 103497 added to function.preg-match

Is there documentation on using non / characters to declare a pattern? Just spent an hour looking a regular expression created with "@<regexp>@" because it searches for the / character and the code's writer probably did not want to escape the code. Did some more test and I was able to create a functioning pattern using a pair of +, !, and various symbols. ---- Server IP: 69.147.83.197 Probable Submitter: 173.46.10.114 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- https://master.php.net/note/edit/103497 Del: integrated -- https://master.php.net/note/delete/103497/integrated Del: useless -- https://master.php.net/note/delete/103497/useless Del: bad code -- https://master.php.net/note/delete/103497/bad+code Del: spam -- https://master.php.net/note/delete/103497/spam Del: non-english -- https://master.php.net/note/delete/103497/non-english Del: in docs -- https://master.php.net/note/delete/103497/in+docs Del: other reasons-- https://master.php.net/note/delete/103497 Reject -- https://master.php.net/note/reject/103497 Search -- https://master.php.net/manage/user-notes.php
