note 112766 added to reference.pcre.pattern.posix

In regards to the previous comment that says "there are several other differences including different meaning for the symbols ( [ different rules for which symbols need escaping", as far as I can tell from reading http://www.tin.org/bin/man.cgi?section=7&topic=regex there are absolutely no "other differences" except in what the man page calls "Obsolete ("basic'') regular expressions". However, PHP doesn't appear to use the obsolete form of expressions in its POSIX functions. PCRE even supports all of the POSIX named character classes such as [:space:]. ---- Server IP: 69.147.83.199 Probable Submitter: 97.93.84.39 ---- Manual Page -- http://php.net/manual/en/reference.pcre.pattern.posix.php Edit -- https://master.php.net/note/edit/112766 Del: integrated -- https://master.php.net/note/delete/112766/integrated Del: useless -- https://master.php.net/note/delete/112766/useless Del: bad code -- https://master.php.net/note/delete/112766/bad+code Del: spam -- https://master.php.net/note/delete/112766/spam Del: non-english -- https://master.php.net/note/delete/112766/non-english Del: in docs -- https://master.php.net/note/delete/112766/in+docs Del: other reasons-- https://master.php.net/note/delete/112766 Reject -- https://master.php.net/note/reject/112766 Search -- https://master.php.net/manage/user-notes.php
