RE: [PHP] preg_match

Hi there, You are correct that I am stupid to call the manual bad, it was not meant like that. It was that it was not suited to me, and that I actually just wanted to find a solution to my problem directly, and it did not give me that. I have never worked with Regular Expressions before, so I might need to do some more research on that, it seams to be a good tool :) I will do some testing in the CMD to learn how to use it, should not be that big of a deal :) Many times the regex looks like rubbish, but that is just because I do not know the "language" :) Thanks, Peter -----Original Message----- From: Jochem Maas [mailto:jochem@iamjochem.com] Sent: Wednesday, August 09, 2006 6:06 PM To: Peter Lauri Cc: php-general@lists.php.net Subject: Re: [PHP] preg_match Peter Lauri wrote: > Hi, > > > > How do I add so that it checks for a comma , in this preg_match. I think the > documentation is not that good for the pref_match: it's a lot better than you spelling of preg_match. the subject of regexps is very complex, the documentation reflects that - but to call them 'not that good' is rather a disservice to the people that wrote them imho. I taught myself regexps primarily using the php docs - which is a testament to how good they are. :-) > > > > preg_match('/^[a-z0-9-_\'() +]*$/i', $s); $q = chr(39); // makes for easier cmdline testing !?E#$@ function test($s) { global $q; echo "\"$s\" is ",(preg_match("#^[a-z0-9\\-_\\$q\\(\\), \\+]*$#i", $s)?"true":"false"),"\n"; // I escaped everything char that has special meaning in a regexp // backslashes are themselves escaped in double quotes strings. // I used different regexp delimiters (#) - just my preference } test("foo"); test(","); test("()"); test("(123)"); test("(123,456)"); test("(+123,456)"); test(" (+123,456) "); test(" $q(+123,456) $q"); > > > > /Peter > > > > > >
