Facebook APIs

http://wiki.developers.facebook.com/index.php/API#API_Methods

* A lot of handy functions provided with a Facebook Object.
* For example: Users.getInfo
o Returns a wide array of user-specific information for each user identifier passed, limited by the view of the current user.

Examples of using APIs

* Get current user’s first name and last name

$user_details=$this->facebook->api_client->users_getInfo($uid, array(‘last_name’,'first_name’)); $data['first_name']=$user_details[0]['first_name']; $data['last_name']=$user_details[0]['last_name'];

Facebook Query

http://wiki.developers.facebook.com/index.php/FQL

* Facebook Query Language, or FQL
o allows you to use a SQL-style interface to more easily query the same Facebook social data that you can access through other Facebook API methods (assuming your application has access!).
* It can be very concise and powerful!

Examples of using FQL

http://wiki.developers.facebook.com/index.php/Sample_FQL_Queries

* Get the names of the groups of which u1 is a member:

SELECT name FROM group WHERE gid IN (SELECT gid FROM group_member WHERE uid = ”u1”)

* In PHP, you write:

$query = “YOUR QUERY HERE”; //(see above examples)

$array = $facebook->api_client->fql_query($query);

* The returned array is multidimensional, so

$attribute = $array[0]['attribute'];

* If there are no rows returned, check to see if there are any results like this:

if ($result != NULL)
