PHP unable to read object from json encode

Question

I am sending a request to youtube API to get a playlist:

      // make GET request to the YouTube API
      $response = wp_remote_request( 'https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId='.$playlist_id.'&key='.$api_key.'&order=date&maxResults=25',
      array(
          'method'     => 'GET'
        )
      );

After getting it I would like to have it in JSON so I am using:

      $json = wp_remote_retrieve_body($response);
      $json_encoded = json_encode($json, true);

If I am right this now should be a JSON representation of the supplied value. So I am getting:

{
    "kind": "youtube#playlistItemListResponse",
    "etag": "\"p4VTdlkQv3HQeTEaXevLePAydmU/Q2DmelXR9Ne48evrmJE9Q4yVvpU\"",
    "nextPageToken": "CAoQAE",
    "pageInfo": {
        "totalResults": 36,
        "resultsPerPage": 25
    },
    "items": [ ...

And I would like to store only the items. One would think that I can now access them via:

$json_encoded['items'];

And then store it into WordPress db like this:

      // if we have any items update the db with those results
      if ( isset ( $json_encoded['items'] )) {
        $videos['json'] = $json_encoded['items'];
        update_option( 'wpc_ylp_videos', $videos );
      }

Well, unfortunately, I get the following error:

Warning: Illegal string offset 'items' in /Users/tobias/Sites/videos.dev.cc/wp-content/plugins/videos/includes/videos.php on line 61
"

AND

Notice: Undefined index: json in /Users/tobias/Sites/videos.dev.cc/wp-content/plugins/videos/includes/videos.php on line 67

I am sure I am doing something wrong but can not wrap my head around this. How can I access the items object? Is my usage of json_encode right?

json_encode converts to a string. I believe you are looking for json_decode php.net/manual/en/function.json-decode.php — Ty Bailey

For those of you that don't read comments; The answer is to use json_decode() instead of json_encode().

json_encode() converts to a string.
