I am trying to get the new facebook php sdk setup on my site. I'm running the latest stable version of php. I have never messed with namespaces before. Can someone tell me what I'm doing wrong?
I get this error
Fatal error: Class 'FacebookSession' not found in
When I run this code
FacebookSession::setDefaultApplication( 'xxx','yyy' );
.....

Problem was due to PEAR being installed on the server for email. The include path in php settings was modified.
I actually removed PEAR, set PHP back to it's default include path and switched email to swiftmailer.
You don't need to use the full path to the Facebook SDK unless you are trying to access it from a totally different location. You should be able to access it using a relative path, like lib/fb/Facebook/GraphSessionInfo.php, assuming your index.php file is located in the site folder.
Also, try doing the following and see if you still get an error:
Facebook\FacebookSession::setDefaultApplication( 'xxx','yyy' );
