Is there a good way (PHP class) to acces Gmail Contacs?

Is there a good way (PHP class/function) to access Gmail Contacts List? If not where I开发者_JAVA技巧 can start to build a class?

OpenInviter, it's open source and works with Gmail and many more.

I know libgmailer (class GMailer) (requires CURL and OpenSSL).

Mail management: read, compose, save draft, send, apply labels, remove labels, apply star, remove star, download attachment, search, etc.

Account management: edit filters, edit contact list, edit label list, edit Gmail perferences, etc.

Maybe you could try with Zend Framework's Zend_GData http://framework.zend.com/manual/en/zend.gdata.html? And here's an example: http://blog.charlvn.com/2008/11/google-contacts-api-with-zend-framework.html how to use it.
