This simple code validates an email address to ensure that it complies with standard formatting.

You can put this in your model like so:


class Person < ActiveRecord::Base
validates_format_of :email, :with => /^\S+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,4}|[0-9]{1,4})(\]?)$/ix
end


If you have PHP code - try this..


$valid_email = preg_match('/^\S+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,4}|[0-9]{1,4})(\]?)$/', $email);
