How can the wikipedia api hide their source code?
<p>I have a wiki api site:
<a href="http://en.wikipedia.org/w/api.php" rel="nofollow">http://en.wikipedia.org/w/api.php</a></p>

<p>when I save the api.php, I can't see any post or get method behind that.... but I try to write a simple php program.... like this</p>

<p>test.php:</p>

<pre><code>&lt;?php echo("testing"); ?&gt;
</code></pre>

<p>when I updated to server, and save the test.php, people can see my source code. but after I downloaded the api.php, I don't see any php source code from the api.php, but I can pass parameter to the api.php, how can they do so? Thank you.</p>
