Yet another great class found on the php classes website.
This one has been in my draft folder for a while (the place i keep my articles ideas ), and finally it came time to write about it (manage to put my laziness away and write it).
This package can be use to get the contacts of friends of different e-mail providers and social networks.
It can access the Web services servers of different networks to retrieve the contacts of friends of a given user.
Each network is accessed by the means of plug-in classes. Some plug-ins support sending invitation messages to friends to be added to the user contacts.
The class currently comes with plug-ins that support :
* Windows Live (Hotmail)
The class is very easy to use, and comes with a very detailed example of how you can implement it.
Hope it helps you in your development.
