title: Event listener for MySQL table change?
body: <p>Is there a php/javascript/mysql/ajax event listener or method that can call a function each time the data in a MySQL table changes - such as when a new row is added, or a row changes/is deleted.</p>
  
  <p>Or am I looking at it from the wrong perspective, I'm still learning AJAX.</p>
  
  <p>Just looking to be pointed in the right direction, I couldn't find anything. Thanks.</p>
  
  <p><strong>Edit</strong>
  Basically when a user is sitting on my site, if new data is added to the database on the server from another source (not because of an action of this user), I want to be able to call a function to asynchronously load that new data for this user. </p>
