note 72997 added to reference.pcre.pattern.modifiers

When adding comments with the /x modifier, don't use the pattern delimiter in the comments. It may not be ignored in the comments area. Example: <?php $target = 'some text'; if(preg_match('/ e # Comments here /x',$target)) { print "Target 1 hit.\n"; } if(preg_match('/ e # /Comments here with slash /x',$target)) { print "Target 1 hit.\n"; } ?> prints "Target 1 hit." but then generates a PHP warning message for the second preg_match(): Warning: preg_match() [function.preg-match]: Unknown modifier 'C' in /ebarnard/x-modifier.php on line 11 ---- Server IP: 64.71.164.2 Probable Submitter: 209.18.139.113 ---- Manual Page -- http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php Edit -- https://master.php.net/note/edit/72997 Del: integrated -- https://master.php.net/note/delete/72997/integrated Del: useless -- https://master.php.net/note/delete/72997/useless Del: bad code -- https://master.php.net/note/delete/72997/bad+code Del: spam -- https://master.php.net/note/delete/72997/spam Del: non-english -- https://master.php.net/note/delete/72997/non-english Del: in docs -- https://master.php.net/note/delete/72997/in+docs Del: other reasons-- https://master.php.net/note/delete/72997 Reject -- https://master.php.net/note/reject/72997 Search -- https://master.php.net/manage/user-notes.php
