用PHP打印多维数组的特定部分

Question

我对编程和PHP完全陌生。我正试图在我的PHP页面上显示谷歌驱动器中的文件列表。我已经能够在谷歌驱动器上获得所有可用信息的详细阵列，但我只想要特定的信息。代码和数组的结构如下：

代码(基于Google Drive API(：

$results = $service->files->listFiles(); 
print "<pre>";
print_r ($results);
print "</pre>";
Array Output:

这只是两个文件的数据。我只需要在PHP中打印'[embedlink]'和'[title]'。

Answer 1

您只需要遍历数组(foreach(，并从每个文件中请求所需的索引。

foreach($results['items'] as $file){
echo $file['embedlink'];
echo $file['title'];
//or do anything else with them...
}
