I am trying to make a small web app as a side project that uses the Google API PHP client. After the application has been granted permission by the user, it requests the playlists of the user (mine=true parameter) and then it should save the names and IDs into an array. The problem I am having is the result of my limited PHP knowledge.
I am instantiating the Google and YouTube clients like this:
$client = new Google_Client();
$youtube = new Google_Service_YouTube($client);
Then I am making a request to the YouTube API like this :
$listResponse = $youtube->playlists->listPlaylists('snippet', $queryParams);
The $listResponse variable returns the correct results but it is an object which makes it very peculiar to me. This object contains several arrays and it makes it difficult for me to store this data. Then comes the issue of pagination. What is the best way for me to save the results of this request into an array (so I can store it in a database later) and add on top of these results the next page of results as required by pagination?
This is an example of the response from the API with two results (var_dump($listResponse)):

I cant really help you covert the object to your own object as we dont know what your object looks like.
I can tell you that the object returned has an array called items this is a single row of type playlist. I would start with looping though $listRespose->items
as for the pagination. Something like this should work
$token = $results->getNextPageToken();
while($token != null) {
$params = array('pageToken' => $token);
$listResponse = $youtube->playlists->listPlaylists('snippet', $params);
$token = $results->getNextPageToken();
}
