So I could only find one other PHP based HTTP digest auth example on the internet…and it looked as though it might not even work. I wrote an abstract class as a base that allows you to easily build your own implementation.
You’d use it like so:
class MyAuth extends HTTPDigestAuth {
// Implementation of abstract methods
}
$authenticator = new MyAuth();
$user = $authenticator->authenticate();
if(!$user) {
die();
}
