How can I access an object attribute that starts with a number?
<p>I'm working on an existing code base and got back an object with an attribute that starts with a number, which I can see if I call <code>print_r</code> on the object. </p>

<p>Let's say it's <code>$Beeblebrox-&gt;2ndhead</code>. When I try to access it like that, I get an error:</p>

<pre><code>Parse error: syntax error, unexpected T_LNUMBER, expecting T_STRING or T_VARIABLE or '{' or '$'
</code></pre>

<p>How can I get that attribute?</p>
