Fortunately, PHP (5 and later) comes with a handy set of functions and filters that make testing for email address validity a snap.

Getting email addresses you collect — for a newsletter, say, or for password retrieval — to at least conform to standards (if not ensure ) is crucial, of course, and extremely tricky.

This is a method I created in a Utility class: Of course, you can show some warning or tooltip in front-end when user typed "strange" email to help him to avoid common mistakes, like no dot in domain part or spaces in name without quoting and so on.

But you must accept the address "[email protected]" if user really want it. But you have old function on server, you cant update in some cases.

If you want to know which regex pattern PHP (currently) uses to validate email addresses see the PHP source.

For example, how many times have you come across email addresses such as: “Test Email Please Ignore!There are three rfc's regarding emailaddresses and writing a regex to catch wrong emailadresses and and the same time don't have false positives is something no mortal can do.Check out this list for tests (both failed and succeeded) of the regex used by PHP's is the best option.Most of them are far too simple and ill-equipped to adequately deal with something as complex as an email address.While searching Google for terms such as “PHP validate email regex example”, I noticed that about 60-70% of the listed results were utter mush.

Most of these PHP snippet websites contained crappy regex examples that will actually reject valid email addresses.
