class.openid.phpは、
lightopenidよりも単純で小さいため、勉強しようとしています。私の目的のために、200行が重要です。class.openid.phpはgoogle openIDで作業していますか？
ERROR CODE: OPENID_NOSERVERSFOUND
ERROR DESCRIPTION: Cannot find OpenID Server TAG on Identity page.
それはclass.openid.php（すべてのバージョン）を作成することが可能である、そのようなことを行うためにGoogleのOpenIDとどのように動作します。しかし、class.openid.phpは私には、GoogleのOpenIDのhttps://www.google.com/accounts/o8/idで、このようなエラーをプリントを動作しませんか？
HTML：私は、誰かが私が持っているコードを見たい場合には、すべての<?を見つけ、<?phpでTHAMを交換しなければならなかった
class.openid.phpはhereを撮影することができますが、それは箱から出して私のために働いていませんでしたインタフェースページ：

問題は、クラスを拡張して欠落している機能を追加することができるため、一般的に**はい**で回答できます。しかし、私はそれがあなたが求めているものではないと思います、私はあなたが探しているすべてのものを持っているクラスの新しいバージョンのダウンロードリンクを好むと思いますよね？ – hakre
これらの200行のコードはあなたにとって問題ではないと私は本当に思っています。それにもかかわらず、OpenID 2をサポートしたい場合。0と属性交換を行うには、別のライブラリを使用する必要があります。そして、ちょうどその行数は関係ないことを証明するために、私はあなたが使用したクラスよりも、それを小さくするlightopenidに（問題のクラスが著しく欠けているコメントそのうち半分、）いくつかのコードを削除したします。http：//ペーストビン.com/fE8qT3kW。それは属性を取得するためのサポートを欠いものの、それはまだ、OpenIDの両方のバージョンをサポートしています。要約すると、LightOpenIDは複雑でも肥大でもありません。 – Mewp
