Have you looked @ https://developers.google.com/youtube/v3/docs/playlistItems/list (Examples section > click PHP)? I honestly have no idea if this will help you or not, but the STE in me just can't resist debugging a problem.
There's actually a working test at the very bottom, too. I was able to pull the data from your linked playlist using part=snippet and playlistId=PLWRYhlET-aA4OKp4w6qb-YBQXRvbYOXWi
The code sample below calls the API's playlistItems.list
method to retrieve a list of videos uploaded to the channel associated with the request. The code also calls the channels.list
method with the mine
parameter set to true
to retrieve the playlist ID that identifies the channel's uploaded videos.
This example uses the PHP client library.
<?php
// Call set_include_path() as needed to point to your client library.
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';
session_start();
/*
* You can acquire an OAuth 2.0 client ID and client secret from the
* Google Developers Console <https://console.developers.google.com/>

* Please ensure that you have enabled the YouTube Data API for your project.

$OAUTH2_CLIENT_ID = 'REPLACE_ME';
$OAUTH2_CLIENT_SECRET = 'REPLACE_ME';
$client = new Google_Client();
$client->setClientId($OAUTH2_CLIENT_ID);
$client->setClientSecret($OAUTH2_CLIENT_SECRET);
$client->setScopes('https://www.googleapis.com/auth/youtube');
$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],
FILTER_SANITIZE_URL);
$client->setRedirectUri($redirect);
// Define an object that will be used to make all API requests.
$youtube = new Google_Service_YouTube($client);
if (isset($_GET['code'])) {
if (strval($_SESSION['state']) !== strval($_GET['state'])) {
die('The session state did not match.');
}
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: ' . $redirect);
}
if (isset($_SESSION['token'])) {
$client->setAccessToken($_SESSION['token']);
}
// Check to ensure that the access token was successfully acquired.
if ($client->getAccessToken()) {
try {
// Call the channels.list method to retrieve information about the
// currently authenticated user's channel.
$channelsResponse = $youtube->channels->listChannels('contentDetails', array(
'mine' => 'true',
));
$htmlBody = '';
foreach ($channelsResponse['items'] as $channel) {
// Extract the unique playlist ID that identifies the list of videos
// uploaded to the channel, and then call the playlistItems.list method
// to retrieve that list.
$uploadsListId = $channel['contentDetails']['relatedPlaylists']['uploads'];
$playlistItemsResponse = $youtube->playlistItems->listPlaylistItems('snippet', array(
'playlistId' => $uploadsListId,
'maxResults' => 50
));
$htmlBody .= "<h3>Videos in list $uploadsListId</h3><ul>";
foreach ($playlistItemsResponse['items'] as $playlistItem) {
$htmlBody .= sprintf('<li>%s (%s)</li>', $playlistItem['snippet']['title'],
$playlistItem['snippet']['resourceId']['videoId']);
}
$htmlBody .= '</ul>';
}
} catch (Google_Service_Exception $e) {
$htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
htmlspecialchars($e->getMessage()));
} catch (Google_Exception $e) {
$htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
htmlspecialchars($e->getMessage()));
}
$_SESSION['token'] = $client->getAccessToken();
} else {
$state = mt_rand();
$client->setState($state);
$_SESSION['state'] = $state;
$authUrl = $client->createAuthUrl();
$htmlBody = <<<END
<h3>Authorization Required</h3>
<p>You need to <a href="$authUrl">authorize access</a> before proceeding.<p>
END;
}
?>

So, when I plug part=snippet and playlistId=PLWRYhlET-aA4OKp4w6qb-YBQXRvbYOXWi into the Test section:
Response
200 OK
{
"kind": "youtube#playlistItemListResponse",
"etag": "\"jOXstHOM20qemPbHbyzf7ztZ7rI/D3G7y_ZyUpWi54pFyRDXR18VzfU\"",
"nextPageToken": "CAUQAA",
"pageInfo": {
"totalResults": 38,
"resultsPerPage": 5
},
}
Seems to me that there's data in there that you're needing to convert into a json array, but if that conversion process is your actual issue, then I gots no idea.
