Php email validation

[keyboard]

Thanks for your suggestion traq!
So, how do I actually use it?
Like this -

if(checkemail($email)) {
	echo 'yes';
} else {
	echo 'no';
}

? I'm sorry, but I've never really used php functions...

yeah, though you probably won't be echoing anything right then. Maybe more like

//  . . .

if( !checkemail( $_POST['useremail'] ) ){
    /*  throw an error  */
}

//  . . .

Thanks for that traq! (the echo was just to try and tell if I was doing it right )
