Regular Expression (PHP)

[Ben643]

I'm trying to add a regular expression to a registration page I've done in PHP but I'm absolutely useless with them! Anyone able to help?

I only want people to be able to register with an email from a specific university...

So I need a regular expression to check, for example, that the email address ends with @dmu.ac.uk

I thought I'd try my luck with: preg_match("@dmu.ac.uk$", $pEmail) just to test it but just got an error (unsurprisingly). Guesswork doesn't often work with regular expressions

Any help would be appreciated.

Thanks in advance.

It needs to be

if (preg_match("/@dmu\.ac\.uk$/", $checkThis)) {
}

That should work The dot is a special char in reg exps so needs escaping....you should probably also validate the bit before the @ sign to make sure it's only valid characters allowed in there.

No need to use a regexp for that - strpos will be faster

Perfect, it worked. Thanks

Yeah, I've done that already with this huge function I found!

Doh! Just put the regular expression in. I'll have a look into that too, thanks.
