title: PHP code does not run
body: <p>I'm trying to run a PHP code by the click of a button, but it does not seem to work. I'm running this on a MAPM server.</p>
  
  <pre><code>&lt;html&gt;
      &lt;head&gt;
      &lt;/head&gt;
      &lt;div onClick="count();"&gt;Click!&lt;/div&gt;
      &lt;script&gt;
  function count() {
      var xhr;
      if (window.XMLHttpRequest) {
          xhr = new XMLHttpRequest();
      } else {
          xhr = new ActiveXObject("Microsoft.XMLHTTP");
      }
      xhr.open('GET', 'count.php');
      xhr.send();
  }​
      &lt;/script&gt;
  
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>In the PHP file (count.php) we have this code:</p>
  
  <pre><code>&lt;?php
  Print "Hello, World!";
  ?&gt;
  </code></pre>
