title: Can't execute PHP in MAMP
body: <p>I installed MAMP in my macbook with osx mavericks, all preferences are the defaults.
  I copied my test.html to /Applications/MAMP/htdocs and go to <code>http://localhost:8888/test.html</code>
  and the display is: <code>one three</code></p>
  
  <p>and the test.html file:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;Example&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  one
  &lt;?php
  echo 'two ';
  ?&gt;
  three
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The 'two ' of php doesn't appear, anyone knows why?</p>
