title: Is there a way to reloaded an already loaded PHP class?
body: <p>Once a PHP object is already loaded on PHP, is there a way to reload it?</p>
  
  <p>The motivation of this question is a PHP watcher in a ReactPHP server. Using ReactPHP, the kernel can be reloaded without having to stopping the server itself, but even if one PHP file has changed, the PHP code is already loaded in memory, and nothing happens.</p>
