Answer 1

It will not only validate email address, but also sanitize it for unexpected characters:

$email = $_POST['email'];
$emailB = filter_var($email,   
 FILTER_SANITIZE_EMAIL); 
 if(filter_var($emailB,   
 FILTER_VALIDATE_EMAIL) === false ||  
 $emailB != $email ) { echo "This email adress 
  isn't valid!"; exit(0);
}
