preg_match

[justinwhite]

Hello,

 

I am quite new with PHP and need a preg_match for email validation like

 

if(!preg_match(-Email Stuff?-, $email)) {
die('Invalid email address');
}

 

So, how would I do that?

This is unfortunately not an easy subject. It's hard, if not impractical, to create a perfect regex for email validation. RFC2822 doesn't help either. It was written with wide support in mind, not simplicity.

 

With that in mind you should choose the one that suits your fancy. For examples:
