String comparison

[Praetorian]

I'm using this eregi string to validate an email. It works fine for most emails, but I can't figure out how to get it to allow foriegn email addresses such as .co.uk. Any help would be greatly appreciated.

^[a-z0-9]+([!#$%*/?|^{}`~&'+-=_][a-z0-9])*@[a-z0-9]+([!#$%*/?|^{}`~&'+-=_][a-z0-9])*.[a-z]{2,3}$

I believe

^[a-z0-9]{2,}[a-z0-9]+\@[a-z0-9]{2,}\.[a-z]{2,3}$

Would work. Not 100% sure about it. I'll look through my old projects to get one that works for everything if you need and that doesn't work.

^[a-z0-9]{2,}(\.[a-z0-9]+)*@[a-z0-9]{2,}(\.[a-z0-9]+)*\.[a-z]{2,4}$That should work. You have to allow for dots inside the user name and domain.user.user.user@domain.domain.domain.tld
