MongoDB PHP查询多维数组实现方法？

最近在学习Mongdb，数据结构如下，从豆瓣API拿到的数据：

在mongod里 find('{"casts.name":"杨幂"}') 是可以查询到结果的。 但是用PHP怎么都实现不了查询 2维以上多维数组里的值，求详解。

你的多维的查询条件是什么

<code class="lang-php">// 测试这样ok
$rows = $mongo->test->test->find(array(
    'casts.name' => array('$in'=> array('杨幂','刘恺威'))
));
foreach ($rows as $row) {
    echo "{$row['title']}<br>";
}
</code>

请自己查一下 $elemMatch 在mongo中的用法。
是专门解决你这个问题的.
