Re: PHP regex to match email addresses

[Kevin Schroeder <kevin@xxxxxxxx>]

RFC 2822 regex

(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])

My suggestion?  Use Zend_Validate_EmailAddress.

Folks:

I need to find a regular expression that matches email addresses.

I've got one that mostly works ... but not entirely.

'/[\w\.-]+@[\w-\.]+\.[\w\.]{2,5}/'

The problem is, it doesn't understand when there is a plus sign in the
email address (like david+list@xxxxxxxxxxxx).

If I change the regex to be '/[\w\.-\+]+@[\w-\.]+\.[\w\.]{2,5}/', it
doesn't match anything.

Any suggestions?

Thanks!

david
