note 89545 added to regexp.reference

The PHP docs here use 'caseless' for 'case insensitive'. ---- Server IP: 69.147.83.197 Probable Submitter: 216.55.154.9 ---- Manual Page -- http://www.php.net/manual/en/regexp.reference.php Edit -- https://master.php.net/note/edit/89545 Del: integrated -- https://master.php.net/note/delete/89545/integrated Del: useless -- https://master.php.net/note/delete/89545/useless Del: bad code -- https://master.php.net/note/delete/89545/bad+code Del: spam -- https://master.php.net/note/delete/89545/spam Del: non-english -- https://master.php.net/note/delete/89545/non-english Del: in docs -- https://master.php.net/note/delete/89545/in+docs Del: other reasons-- https://master.php.net/note/delete/89545 Reject -- https://master.php.net/note/reject/89545 Search -- https://master.php.net/manage/user-notes.php
