Getting A MongoId out of an array
<p>How would I call the id by itself?</p>

<pre><code>Array
(
    [0] =&gt; Array
        (
            [_id] =&gt; MongoId Object
                (
                    [$id] =&gt; 4f98930cb1445d0a7d000001
                )
        )

)
</code></pre>

<p>I thought it would be:</p>

<pre><code>echo $userInfo[0]['_id']-&gt;['$id'];
</code></pre>
