title: my .PHP file doesnt seem to work
body: <p>i have a rather simple .PHP file with the following code:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
  
  &lt;/head&gt;
  
  &lt;body&gt;
  &lt;p&gt;hello world&lt;/p&gt;
   &lt;?php echo "test";
   ?&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>yet when i run it all i see is "hello world", i checked firebug and it showed me this <img src="https://i.stack.imgur.com/TQTJ2.png" alt="enter image description here"></p>
  
  <p>and in chrome it simply comments the php out</p>
  
  <p><img src="https://i.stack.imgur.com/ntKS5.png" alt="enter image description here"></p>
  
  <p>am i missing something important here?</p>
