Get all activities from a Google+ page and access the content

Question

I`m trying to obtain all activities from a G+ page using Google PHP Api Client:

$service = new \Google_Service_Plus($this->client);
    $activities = $service->activities->listActivities($data['page_id'], 'public');

The result is an array of Google_Service_Plus_Activity objects. The problem is that I want to access the content of one of the activities to search for a string, but this is under ["modelData":protected]=> array(1) as ["content"]=> string(int) "my_string". Is there a possibility to access the content?

var_dump($activity):

  object(Google_Service_Plus_Activity)#268 (28) { ["internal_gapi_mappings":protected]=> array(0) { } ["accessType":protected]=> string(23) "Google_Service_Plus_Acl" ["accessDataType":protected]=> string(0) "" ["actorType":protected]=> string(33) "Google_Service_Plus_ActivityActor" ["actorDataType":protected]=> string(0) "" ["address"]=> NULL ["annotation"]=> NULL ["crosspostSource"]=> NULL ["etag"]=> string(57) ""RqKWnRU4WW46-6W3rWhLR9iFZQM/t4CM2-QFWMd8gXogVxXGqNUhGSA"" ["geocode"]=> NULL ["id"]=> string(35) "z133dxyyhuaqf5tqd04cebxrtuykyfc5vi0" ["kind"]=> string(13) "plus#activity" ["locationType":protected]=> string(25) "Google_Service_Plus_Place" ["locationDataType":protected]=> string(0) "" ["objectType":protected]=> string(34) "Google_Service_Plus_ActivityObject" ["objectDataType":protected]=> string(0) "" ["placeId"]=> NULL ["placeName"]=> NULL ["providerType":protected]=> string(36) "Google_Service_Plus_ActivityProvider" ["providerDataType":protected]=> string(0) "" ["published"]=> string(24) "2015-03-20T09:03:51.236Z" ["radius"]=> NULL ["title"]=> string(103) "http://www.company-civ.localhost.com/provider/endpoint/validation_social/google?validate=017f5b8e-cee0..."

Answer 1

The solution is (found it finally):

$service = new \Google_Service_Plus($this->client);
//you can also set range of post (max 100)
$optParams = array('maxResults' => 100);
$activities = $service->activities->listActivities('{PAGE_ID}', 'public',$optParams);

foreach($activities as $activity) {
   $result = $activity->getObject();
}

The $result is an Object which contains a public property, content So:

$result->content;

Answer 2

You can access the content by using: $activity->getObject()->content
