我对编程和PHP完全陌生。我正在尝试将Google驱动器中的文件列表显示在我的PHP页面上。我已经能够获取Google驱动器上所有可用信息的详细数组，但我只需要特定信息。代码和数组的结构如下：
Code (based on Google Drive API):
$results = $service->files->listFiles();
print "<pre>";
print_r ($results);
print "</pre>";
Array Output:

这仅是两个文件的数据。我只需要在PHP中打印'[embedlink]'和'[title]'。
您只需要遍历数组（foreach）并从每个文件中索取所需的索引。
foreach($your_unnamed_array_lets_call_it_google_drive_data['items'] as $file){
echo $file['embedlink'];
echo $file['title'];
//or do anything else with them...
}
