note 43540 rejected from function.preg-match by aidan

Note Submitter: Zach Johnson ---- I'm confused about the point made by "thhof at freenet dot de." My expression will accept an email address such as name@domain.co.uk as will his expression. However, his expression also accepts those in the form of name@.domain.com which is NOT valid. (No leading dot's.) If we want to get really technical, the following is every better than what I posted before: preg_match( "/^[-^!#$%&'*+\/=?`{|}~.\w]+@" . "[a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])*" . "(\.[a-zA-Z0-9]([-a-zA-Z0-9]*[a-zA-Z0-9])*)+$/", $email ) This allows for name@my-subdomain.my-domain.com but does not allow for name@-mydomain-.com. (No leading or trailing dash's.) If you'd like, you could change my expression to force it to end with 2-6 LETTERS only, but who knows what TLD's they will come up with in the future. cheers, Zach
