Well, most of the options listed on that page don't have provider support, so I think your options come down to OpenID Enabled's php-openid or Zend_OpenId. I'm partial to the openidenabled libraries myself, but then again, I was on the team that wrote them. php-openid is generally compatible with a wider range of PHP versions, and its test coverage is pretty extensive.
I don't really know much about the Zend offering, but it might be appropriate if you're fortunate enough to not need PHP 4 compatibility and like that framework thing they do.
Finally, there's option 2, which I think the best choice. There are enough choices of PHP libraries listed in http://openid.net/developers/libraries/#php . I imagine it would be easy to use one of these libraries to extend your existing authentication mechanism to provide OpenID authentication service but I can't be sure as I have not tried any of them yet.

好吧，该页面上列出的大多数选项都没有提供商支持，所以我认为您的选项可以归结为 OpenID Enabled 的 php-openid 或 Zend_OpenId。我自己偏爱 openidenabled 库，但话又说回来，我是编写它们的团队之一。 php-openid 通常与更广泛的 PHP 版本兼容，并且其测试覆盖范围相当广泛。
我对 Zend 产品了解不多，但如果您足够幸运，不需要 PHP 4 兼容性并且喜欢他们所做的框架，那么它可能是合适的。

首先浏览官方 OpenID 开发者网站 @ http://openid.net/add -openid/become-a-provider/
在那里，它为您提供了三个选项：
选项 1 可能不是您想要的选项因为，因为您希望您的网站成为您上面暗示的提供商。
如果您有时间和能力来实施，选项 3 是可以的。尝试浏览 http://openid.net/specs/openid-authentication-2_0.html 看看您的开发团队是否能够忍受。
最后是选项2，我认为这是最好的选择。 http://openid.net/developers/libraries/#php 中列出了足够的 PHP 库选择。我想使用这些库之一来扩展现有的身份验证机制以提供 OpenID 身份验证服务会很容易，但我不能确定，因为我还没有尝试过其中任何一个。
祝你好运，万事如意！
Start with browsing through the official OpenID developer website @ http://openid.net/add-openid/become-a-provider/
There, it gives you three options:
Option 1 may not be the one you would aiming for, since you want your site to be a provider as you have hinted above.
Option 3 is ok if you have the time and capacity to implement it. Try going through http://openid.net/specs/openid-authentication-2_0.html and see if your development team can stomach that.
Finally, there's option 2, which I think the best choice. There are enough choices of PHP libraries listed in http://openid.net/developers/libraries/#php . I imagine it would be easy to use one of these libraries to extend your existing authentication mechanism to provide OpenID authentication service but I can't be sure as I have not tried any of them yet.
Good luck and godspeed!
