PHP Tutorial : Validate email address – simple way with filter_var() function

While browsing php.net without any scope I discovered a very cute & nice way to replace the usual regular expression email checking thing.

That way is via filter_var() php function which does the things 10 times faster :

<?php
$email = "someone@example.com";

if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
echo "Invalid email address";
}
?>
