PHP email validation function script snippet check correct emails

thanks to www.webune.com for helping us with this questions.



i needed a function or class to check on my user's email to verify that the emails address they were providing was correct. so here is a useful email verification function.



this function just checks that the format of the email is correct:

function check_email($email) {

	$validation = TRUE;

	if(!eregi("^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,4})$", $email)) {

		$validation = FALSE;

	}

	return $validation;

} 

hope this helps



USAGE:

if(!check_email($mail)) { 

	$error .= "EMAIL  - The Email You Provided Is not Valid";

}
