好的我正在调用google places API并获取一个JSON对象。我已经能够使用Ajax使用此对象，但现在我必须将我的代码集成到Wordpress实例中，并且我在functions.php中进行API调用，因为我想使用get_theme_mod（）;方法
因为我对php很新，所以我不知道如何从这个对象输出特定的数据。
我的对象如下，我正在尝试访问此对象返回的评论（全部5）。我知道我可以很容易地用Ajax做到这一点，但我真的很难用PHP中的语法。
这是我的PHP API调用
function do_api_call(){
$url = $my_url;
$data = file_get_contents($url);
$rev = json_encode($data);
echo $rev;
}
