Variable Variable wont work with array
<p>I'm trying to do a variable variable, but it wont work when I use it in the code below. </p>

<p>I keep getting:</p>

<pre><code>Notice: Undefined variable: C in C:\web\apache\htdocs\cats-test.php on line 8
</code></pre>

<p>This only wont work when used with an array. Can you help?</p>

<pre><code>$Consumer = array(
"a" =&gt; "Apparel",
"b" =&gt; "Books &amp; Stationary",
);
$cat = "Consumer";

echo $$cat['a']; //I'm trying to make this $Consumer['a'];
</code></pre>
