Here is some code to validate an email address with PHP:

function isEmail($email)
{
return preg_match('/^(([^()[\]\\.,;:\s@"\']+(\.[^()[\]\\.,;:\s@"\']+)*)|("[^"\']+"))@((\[\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\])|(([a-zA-Z\d\-]+\.)+[a-zA-Z]{2,}))$/', $email);
}


Btw. This regexp string is a litle better than the one proposed by the snippet author.

And for all of you who just wants the regexp and really can't read or hate to read PHP code, here it is:

^(([^()[\]\\.,;:\s@"\']+(\.[^()[\]\\.,;:\s@"\']+)*)|("[^"\']+"))@((\[\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\])|(([a-zA-Z\d\-]+\.)+[a-zA-Z]{2,}))$
