PHP code gets printed on the loaded page
<p>Hi I recently reinstalled my windows and downloaded and installed xampp but for some reason when I try to load any typ of php code the page does not get loaded on the server but is printed on the HTML page.Here is what I mean:</p>

<p><img src="http://i.stack.imgur.com/T3D3J.png" alt="enter image description here"></p>

<p>This image is from the source code of the loaded page.This is the code I am using:</p>

<pre><code>   &lt;?php
        $a = "Maria";

        echo "We're going to Paris with $a";
        echo 'We\'re going to Paris with $a';      
    ?&gt;
</code></pre>

<p>I have restarted xampp 3 times it shows apache and mysql is running.Can anyone tell me what I am missing?</p>
