note 92857 added to intro.pcre

php supports posix regular expressions, but only in the short term. pcre seems capable of most things posix regex does One point of difference is that PCRE requires you delimit your regex, that is: start and end it with a character that is not used elsewhere in the regex, this provides a space after the ending delimiter to put option characters. ---- Server IP: 203.89.181.186 Probable Submitter: 210.48.82.11 ---- Manual Page -- http://www.php.net/manual/en/intro.pcre.php Edit -- https://master.php.net/note/edit/92857 Del: integrated -- https://master.php.net/note/delete/92857/integrated Del: useless -- https://master.php.net/note/delete/92857/useless Del: bad code -- https://master.php.net/note/delete/92857/bad+code Del: spam -- https://master.php.net/note/delete/92857/spam Del: non-english -- https://master.php.net/note/delete/92857/non-english Del: in docs -- https://master.php.net/note/delete/92857/in+docs Del: other reasons-- https://master.php.net/note/delete/92857 Reject -- https://master.php.net/note/reject/92857 Search -- https://master.php.net/manage/user-notes.php
