note 116962 added to regexp.reference.meta

The meta character $ accepts a (one) newline character (\n). (Take a moment to let this information sink in) You might want to (r)trim() your input afterwards if you have a match because otherwise it (still) might not meet a length requirement or other strange stuff might happen when you store the input as-is. ---- Server IP: 72.52.91.14 Probable Submitter: 80.57.181.117 ---- Manual Page -- http://php.net/manual/en/regexp.reference.meta.php Edit -- https://master.php.net/note/edit/116962 Del: integrated -- https://master.php.net/note/delete/116962/integrated Del: useless -- https://master.php.net/note/delete/116962/useless Del: bad code -- https://master.php.net/note/delete/116962/bad+code Del: spam -- https://master.php.net/note/delete/116962/spam Del: non-english -- https://master.php.net/note/delete/116962/non-english Del: in docs -- https://master.php.net/note/delete/116962/in+docs Del: other reasons-- https://master.php.net/note/delete/116962 Reject -- https://master.php.net/note/reject/116962 Search -- https://master.php.net/manage/user-notes.php
