How to use $_GET in a string?
<p>I have a simple PHP file with the following:</p>

<pre><code>&lt;?php
echo 'catid=$_GET["catid"]';
&lt;?&gt;
</code></pre>

<p>When I run the page, the output is:</p>

<pre><code>catid=$_GET["catid"]
</code></pre>

<p>I'm accessing the page as www.abc.com/temp.php?catid=3.  I'd like $_GET to execute so I see:</p>

<pre><code>catid=3
</code></pre>

<p>What am I doing wrong?</p>
