How do I get an array of unknown $_GET values in a URL?
<p>I'm using an online shopping cart which takes items ordered and passes their unique ID through the URL to a process.php page.  So the URL would look something like </p>

<pre><code>process.php?code_1=231&amp;code_2=532&amp;code_3=342
</code></pre>

<p>Another <code>code_x=xxx</code> is generated for each item ordered. On the process.php page, how would I create an array to get the values of the <code>code_x</code> without knowing how many items are ordered?</p>
