Email validation

Actually, it’s even more complicated than I first thought. Just adding the single “‘” character to the range in the regexp did not fix the problem. After much debugging, I taced the problem to magic_quotes and the fact that the user’s email was coming through with “\'” in it. A call to stripslashes() resolved this, but the extent I’ve had to hack this code just to get a valid email address accepted is a bit worrying.

Has no-one else suffered this problem?
