How can PHP be used to automatically redirect users based on the domain they entered?

To automatically redirect users based on the domain they entered, you can use PHP to check the `$_SERVER['HTTP_HOST']` variable which contains the domain name entered by the user. Based on the domain name, you can then use the `header()` function to redirect the user to a different page. 

<?php
$domain = $_SERVER['HTTP_HOST'];

if ($domain == 'example.com') {
    header('Location: https://www.example.com');
    exit();
} elseif ($domain == 'anotherexample.com') {
    header('Location: https://www.anotherexample.com');
    exit();
} else {
    // Handle other domains or redirect to a default page
}
?>
