Solution 1

Here is the way:

        $user_profile = (new FacebookRequest(
        $session, 'GET', '/me/albums'
        ))->execute()->getGraphObject();
        $album =  $user_profile->getProperty('data');

        $album_data = $album->asArray();//this will do all job for you..
        foreach($album_data as $row){
            var_dump($row);
        }

Solution 2

For the New version Graph API v2.5 of Facebook Read read data as below :

$fb = new \Facebook\Facebook([
        'app_id' => 'KEY HERE',
        'app_secret' => 'SECRET HERE',
        'default_graph_version' => 'v2.5',
    ]);
 $asscee_t ="ACCESS TOKEN HERE";
    $response = $fb->get('/me/friends', $asscee_t);
        $get_data = $response->getDecodedBody(); // for Array resonse
        //$get_data = $response->getDecodedBody(); // For Json format result only
        echo $get_data['summary']['total_count']; die; // Get total number of Friends

Solution 3

https://developers.facebook.com/docs/php/GraphObject/4.0.0

getProperty

getProperty(string $name, string $type = 'Facebook\GraphObject') Gets the value of a named key for this graph object. If the value is a scalar (string, number, etc.) it will be returned. If it's an associative array, it will be returned as a GraphObject cast to the appropriate subclass type if provided.

 $user_profile = (new FacebookRequest(
        $session, 'GET', '/me/albums'
    ))->execute()->getGraphObject();

$id = $user_profile->getProperty('id');

I have a facebook graph api request which brings back this response

Facebook\GraphObject Object
(
    [backingData:protected] => Array
        (
            [data] => Array
                    (
                        [0] => stdClass Object
                            (
                                [id] => 111
                                [from] => stdClass Object
                                    (
                                        [id] => 111
                                        [name] => fo bar
                                    )

                                [name] => etc

                            )

I've tried to do $reponse->{'backingData:protected'} but it doesn't work.

Also the next set of results is a link to the graph api but the results from this is pure json.

    [paging] => stdClass Object
        (
            [cursors] => stdClass Object
                (
                    [after] => MTI3NzMzMTQwMzYy
                    [before] => MTAxNTQzNjI5NTY1NDAzNjM=
                )

            [next] => https://graph.facebook.com/v2.0/111/albums?access_token=xxxxv&limit=25&after=yyy
        )

My code

    $user_profile = (new FacebookRequest(
        $session, 'GET', '/me/albums'
    ))->execute()->getGraphObject();

    echo '<pre>'; print_r($user_profile); echo '</pre>';

No I get 'Cannot use object of type Facebook\GraphObject as array'
bhushya almost 10 years

try this $data = $response->getData() then print_r($data);
user9418 almost 10 years

Added code example and @bhushya no that doesn't work either
bhushya almost 10 years

I mean you tried $user_profile->getData() r8? or print_r($user_profile->getProperty('data'));
user9418 almost 10 years

print_r($user_profile->getProperty('data')) produce the same output except for [data] => Array, but when I do $user_profile->getProperty('data')[0] I get errors

@user9418 can you explain what exact error u got?

user9418 almost 10 years

Thanks, but this doesn't provide any output in the foreach, I've added the array output in your post above. But when you try and iterate over it nothing is generated.

The getProperty function does not capture all use cases. For example, the /me/permission returns an extremely ugly data (no surprise there) that cannot be parsed with getProperty or at least I couldn't find a solution on the internet that used it. However, Bhushya's answer is the way to go. Facebook is so stupid that it returned me a graphobject containing an array containing a graphobject for a single data entry. And hardcoding anything like data[0] is completely unacceptable to me as a programmer. Plus, facebook changes things a lot and hides it in their changelog hidden in the dev site. dtf

@bhushya +1 I agree, answer should be accepted. It has somewhat helped with my Stackoverflow Question as it is showing data but the outcome is a mess and I don't know how to get value X
