How to implement Google OpenID authentication in PHP & Test on Localhost

Question

Hi,

I am new to OpenID, and want to implement Google OpenID authentication on my website. I could not found any example.

Can anyone suggest me some good tutorials (step by step) or any working example with code to implement Googl OpenID authentication using PHP.

All helps are appreciated.

Thanks, Navin

Answer 1

use this library http://www.openidenabled.com/php-openid/
for the specs and architecture http://wiki.openid.net/
a simple tutorial will be http://remysharp.com/2007/12/21/how-to-integrate-openid-as-your-login-system/

Answer 2

I'd suggest using LightOpenID. It's small, easy to use, and has working examples. You probably won't need a tutorial to use it.

Another answer suggests using php-openid, but in my opinion, it's too complicated and has too many dependencies (it is, however, more powerful).
