Import custom contacts from Google, Yahoo and AOL in php

Question

I browse the Internet all week, but could not find good resources for importing user contacts from Google, Yahoo and AOL, such as basic email accounts. Actually, I expect the php implementation to do this. when I search, I found that some people offered a third-party application. But here I am looking for my own application for the contact book of import users. Please, anyone can help me do this or give me some idea about this.

Answer 1

You get access to contact data through the API:

http://code.google.com/apis/contacts/

http://developer.yahoo.com/social/contacts/

AOL is missing one
