PHP

The code sample below calls the API's liveBroadcasts.list method to retrieve a list of broadcasts for the channel associated with the request. By default, the request retrieves all broadcasts for the channel, but you can also specify a value for the --broadcast-status option to only retrieve broadcasts with a particular status.

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/>
 * For more information about using OAuth 2.0 to access Google APIs, please see:
 * <https://developers.google.com/youtube/v3/guides/authentication>
 * Please ensure that you have enabled the YouTube Data API for your project.
