Given a beginner PHP assignment, not entirely sure what this means
<pre><code>http://localhost:8888/test.php
</code></pre>

<p>I typed in the above URL to navigate to a blank php file I'd created, and my friend typed the following in my URL bar:</p>

<pre><code>?one=3&amp;two=18 
</code></pre>

<p>(after /test.php)</p>

<p>He said that when I refresh the page, he wants to see the number 21 show up. I'm not entirely sure where to start. Any help for this PHP beginner is appreciated.</p>

<p>Thanks!</p>
