Facebook : Getting the friends list with PHP return JSON format
Problem :
How to get friends list in Facebook with PHP in Json format?
Solution :
Use Facebook SDK https://graph.facebook.com/me/friends
Below is a code fragment in CodeIgniter/PHP on achieving the desired result.
<?php
$fb_config = array(
'appId' => 'xxxxxxxxxxxx',
'secret' => 'xxxxxxxxxxxxxxxxx',
'cookie' => TRUE
);
$this->load->library('facebook', $fb_config);
$user = $this->facebook->getUser();
if ($user) {
try {
$data['user_profile'] = $this->facebook->api('/me');
} catch (FacebookApiException $e) {
$user = null;
}
}
if ($user) { //ok, the user exist, proceed
$access_token = $this->facebook->getAccessToken();
$file = file_get_contents('https://graph.facebook.com/me/friends?access_token=' . $access_token);
$jsonFriends = json_decode($file, true);
$Friends = $jsonFriends['data'];
}
?>
The important part is to save the returned result from Facebook into a file and the decode the result with Json decode function in PHP.
