Please edit the link as Validating Email Addresses The Wrong Way

The right way is

  filter_var('bob@example.com', FILTER_VALIDATE_EMAIL);

Same for validating the domain. And also : http://news.ycombinator.com/item?id=4486108

FILTER_VALIDATE_EMAIL probably is a smarter way to go, but I think context matters a lot. If this is for a consumer web service user@hostname isn't going to be 'valid' for the service.

If this is for a consumer web service, user@existing.dns for a non-existing mail box will be 'valid' according to this link, but still completely useless.

Please see the link I posted.

1/ Using PHP PCRE for email validation is considered harmful

2/ Using filter_var for email validation for a web service is useless

3/ Sending a confirmation link by email is the way to go
