API v3 - 搜索页面返回空白页面

我是一名学习者级别的开发人员......

几周前谷歌关闭了API v2,而我的开发项目已被破坏。我对这个API密钥系统感到困惑。因此,我尝试重建我的脚本,并使用google中的示例代码段替换搜索页。

https://developers.google.com/youtube/v3/code_samples/php#search_by_keyword

我用我生成的api密钥替换了---$DEVELOPER_KEY = 'REPLACE_ME'; replace_me ...这是我的设置。 http://i.imgur.com/0L8IUip.jpg但仍无法正常工作..

我将精确的代码片段发送到名为 v.php 的php文件。当我浏览 domain.com/v.php 时,它显示一个搜索框..当我输入一个关键字并按下搜索按钮时,只显示一个空白页面。我错过了什么?我很困惑,不知道该怎么做。 *我尝试了下面图像的api(服务器和浏览器)。 这是片段。

<?php

  <div>
    Search Term: <input type="search" id="q" name="q" placeholder="Enter Search Term">

  <div>
    Max Results: <input type="number" id="maxResults" name="maxResults" min="1" max="50" step="1" value="25">
  </div>
  <input type="submit" value="Search">
</form>
END;

// This code will execute if the user entered a search query in the form
// and submitted the form. Otherwise, the page displays the form above.
if ($_GET['q'] && $_GET['maxResults']) {
  // Call set_include_path() as needed to point to your client library.
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';

  $DEVELOPER_KEY = '39 digit api key';

  $client = new Google_Client();
  $client->setDeveloperKey($DEVELOPER_KEY);

  // Define an object that will be used to make all API requests.
  $youtube = new Google_Service_YouTube($client);

    // Call the search.list method to retrieve results matching the specified
    // query term.
    $searchResponse = $youtube->search->listSearch('id,snippet', array(

    $videos = '';

    // Add each result to the appropriate list, and then display the lists of
