Problem with regex

Seachmall · 09-03-2008 04:38PM #1

I have this regex (preg_match) but it won't work and I'm not sure why

[PHP]
$regex="/^(Monday|Tuesday|Wednesday|Thursday|Friday|Saturday|Sunday)-([1-9]{1}|[1-2]{1}[0-9]{1}|[3]{1}[0-1]{1})/([1-9]{1}|[1]{1}[0-2]{1})/'20'([0-9]{2})$/";
if(preg_match($regex, $input)){ //<<Line 560
[/PHP]

It should accept strings like Tuesday-5/5/2005 but I get the error

Warning: preg_match() [function.preg-match]: Unknown modifier '(' in path/to/file.php on line 560

Any Help?

Humph. Boards.ie smoked my reply - let's try again!

I believe that the - and / characters after "Sunday)" and before "'20'" respectively should be escaped - ie: "\-" and "\/". Also not sure why you've quoted the '20', probably shouldn't!

Conor.

PS: "[1-9]{1}" and "[1-9]" are the same thing except the latter is less cluttered.

Regex Builder is free and handy if you're on windows.
