[SOLVED] Check for a particular Facebook user permission using PHP

Check for a particular Facebook user permission using PHP

I have the following code to get a users Facebook permissions:

$request = new FacebookRequest( $session, 'GET', '/me/permissions' );
$response = $request->execute();
$graphObject = $response->getGraphObject()->asArray();

I can type:

echo print_r( $graphObject, 1 );

to get a print out of all the permissions BUT I want to check whether or not a particular permission has been granted (in my case 'publish_actions') and act on it. How do I extract this element of the object to perform an 'if' test in PHP?

Solution

Get the raw response and use json_decode

  $publish_actions_perm = '';
    $array = json_decode($response->getRawResponse(), true);
    foreach($array['data'] as $perm){
        if($perm['permission']=='publish_actions'){
            $publish_actions_perm = $perm['status']; //granted
            break;
        }
    }
