How can user login information be accessed and processed in PHP after authentication using .htaccess?

After a user is authenticated using .htaccess, their login information can be accessed and processed in PHP by utilizing the `$_SERVER['PHP_AUTH_USER']` and `$_SERVER['PHP_AUTH_PW']` superglobal variables. These variables contain the username and password entered by the user during the authentication process. Once accessed, the login information can be used for further processing or validation within the PHP script. 

$username = $_SERVER['PHP_AUTH_USER'];
$password = $_SERVER['PHP_AUTH_PW'];

// Use $username and $password for further processing or validation
