#50615 [Bgs]: preg_match() error

ID: 50615 Updated by: rasmus@php.net Reported By: jzumbrun at gmail dot com Status: Bogus Bug Type: Regexps related Operating System: OsX 10.6.1 PHP Version: 5.3.1 New Comment: Oh, and it is documented. Look at the description of the optional 2nd delimiter argument. Previous Comments: ------------------------------------------------------------------------ [2009-12-31 04:21:50] rasmus@php.net The manual doesn't specifically talk about / because the regex separator character is completely configurable. If you use another char, like ~ for example, then you don't have to escape the / eg. preg_match("~$urlClass~", $line); ------------------------------------------------------------------------ [2009-12-31 02:19:37] jzumbrun at gmail dot com Description: ------------ // $line equals line below from file: $route['infox/(.*)'] = "articles/$1"; Basically I have to manually put an \ in front of the / char after infox. preg_quote() wont escape it and the documentation doesnt say i need to escape / chars. preg_match() is forcing me to put one there. Reproduce code: --------------- --- From manual page: function.preg-quote --- $urlClass = '\$route\['infox'/\(\.\*\)'\]'; preg_match("/$urlClass/", $line); Expected result: ---------------- no errors Actual result: -------------- Message: preg_match() [function.preg-match]: Unknown modifier '\' if i use $urlClass = '\$route\['infox'\/\(\.\*\)'\]'; it works (notice the \ infront of the 3rd char after infox) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50615&edit=1
