note 112958 added to function.preg-split

A not good code in example regexp. It should be written preg_split("/[\\s,]+", ... because there is no special symbol \s (like \n for example) and we need to pass exactly \s, not symbol that \s may represent. So we need to escape backslash with backslash $a = "/[\\s,+]/"; echo $a; php> /[\s,+]/ ---- Server IP: 69.147.83.199 Probable Submitter: 178.49.60.206 ---- Manual Page -- http://php.net/manual/en/function.preg-split.php Edit -- https://master.php.net/note/edit/112958 Del: integrated -- https://master.php.net/note/delete/112958/integrated Del: useless -- https://master.php.net/note/delete/112958/useless Del: bad code -- https://master.php.net/note/delete/112958/bad+code Del: spam -- https://master.php.net/note/delete/112958/spam Del: non-english -- https://master.php.net/note/delete/112958/non-english Del: in docs -- https://master.php.net/note/delete/112958/in+docs Del: other reasons-- https://master.php.net/note/delete/112958 Reject -- https://master.php.net/note/reject/112958 Search -- https://master.php.net/manage/user-notes.php
