title: Trigger PHP with javascript
body: <p>I have a PHP process that get's a user's IP address, the page they are on, screen resolution and Date/Time on my website.</p>
  
  <p>I want to put a line of code on my other website such as:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://www.mywebsite.com/tracker.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>In this JavaScript file, it would post the information to a file called tracker.php which then processes the information to put in the database.</p>
