Integration with social networks

Question

PHP

Whether prompt there is a universal service/library. Something similar to Loginza for openID. I would like to have one interface for writing messages vk, fb, twitter, odnoklassniki.

Answer 1

ulogin.ru for example.

Answer 2

Hybrid Auth to the rescue.
For my projects, I had to add support for VK and Odnoklassniki to it.
Immediately put up with the fact that you will not be able to send messages to VK (unless you agree directly with the VK office). Don't know about Odnoklassniki.
