PHP stdClass Object arrays [_]=> syntax
<p>I am trying to access the 1st part of the following Object.</p>

<p>I'm unable to figure out what is the <code>[_] =&gt;</code> syntax?</p>

<p>If I try to print the 1st past of the Object using <code>Body-&gt;[_]</code> it errors out.</p>

<pre><code>[Body] =&gt; stdClass Object
(
    [_] =&gt; http://xyz.com
http://MPQ.com

    [BodyType] =&gt; Text
)
</code></pre>
