Which is the best PHP library for openID integration?
回答1:
For PHP, I find Zend Framework OpenID Component to be really good.
You can also see all available OpenID libraries at this link
回答2:
The PHP OpenID library is good.
回答3:
I'd recommend JanRain's library, they say its used by 80% of all OpenID enabled users, (possibly, it was one of the earliest ones), but you can also use them for OpenID authentication as a service provider using their RPX service, or just get them to do all the work for you via their myOpenID domain tool.
回答4:
Take a look at OpenID's list of libraries.
回答5:
PEAR also has a nice OpenId package.
回答6:
There are many libraries available in the market, just just have to test the best according to your need but if you are thinking for providing Identity as OPENID provider then their are only three libraries there only are PHPOPENID Library, Zend and NetMesh InfoGrid LID. Mostly people choose Zend as they Provide the other types of Framework and make easy to impliment.
