PHP solution to do Google federated login easily?

Question

I see stackoverflow's login system and love the simplicity of clicking one button to log in using Google gmail account.

Is there something available for PHP? I know there's solutions out there for Django and others. But would like a PHP solution.

Thanks!

Answer 1

What you are referring to is actually just OpenID.

Take a look at this post: http://devzone.zend.com/article/3581 or similar.

Answer 2

you can use the PHP OpenID library. This should take care of most of it for you, and comes in PHP4 & 5 flavors.
