[PHP] Validating Subdomain E-mail Addresses Using Regular Expressions

[Jami Moore]

I have been trying all weekend to get this right, and so far it does not
validate an e-mail address with a subdomain.

-- Code --
 
$empatt =
"^[_a-z0-9-]+(\.[_a-z0-9-]+)[EMAIL PROTECTED](\.[a-z0-9-]+)*(\.[a-z]{2,3})$";
   
 if(eregi($empatt, $email))
   {  
        //do stuff
   }
 
-- End Code --
 
>From my understanding, this should allow me to validate an e-mail
address like  <mailto:[EMAIL PROTECTED]>
[EMAIL PROTECTED] Has anyone been able to come up with a
regular expression that will allow php to validate an e-mail address
like this?
