Fortunately, PHP (5 and later) comes with a handy set of functions and filters that make testing for email address validity a snap.FILTER_VALIDATE_EMAIL will erroneously balk at email addresses with long domain names (64 characters or more), and at email addresses with escaped characters (such as "me\"@example.com").Now that you have your easy answer feel free to read on about email address validation if you care to learn or otherwise just use the fast answer and move on. Trying to validate an email address using a regex is an "impossible" task. [email protected] will validate even though it is not a regular domain.The first parameter is the data to filter, in this instance an email address, and the second the filter type, in this instance FILTER_VALIDATE_EMAIL.
