note 85972 added to function.preg-split

Hello all. I need a regex pattern that can explode all "FOO" from any string, and must be case-insensitive. Thus, the same pattern should not explode "FOO" occurrences that is between any of the following characters: "{[('""')]}" (not necessary in this order) anyone can help me? thanks in advance. ---- Server IP: 64.71.164.2 Probable Submitter: 201.86.252.74 ---- Manual Page -- http://www.php.net/manual/en/function.preg-split.php Edit -- https://master.php.net/note/edit/85972 Del: integrated -- https://master.php.net/note/delete/85972/integrated Del: useless -- https://master.php.net/note/delete/85972/useless Del: bad code -- https://master.php.net/note/delete/85972/bad+code Del: spam -- https://master.php.net/note/delete/85972/spam Del: non-english -- https://master.php.net/note/delete/85972/non-english Del: in docs -- https://master.php.net/note/delete/85972/in+docs Del: other reasons-- https://master.php.net/note/delete/85972 Reject -- https://master.php.net/note/reject/85972 Search -- https://master.php.net/manage/user-notes.php
