xn.debug is a debugger for PHP. It is built with several interacting technologies. The core element is a PHP based function, which can be integrated into the application files. This function can be used to inspect PHP elements at nearly every point of code. The function will also be executed again as shutdown function after the application is finished. At this point, HTML output is generated and placed at the end of the server response to the browser. Once the HTML snippet is executed, a virtual debugging window is displayed. Styling is based on a dedicated CSS file and a handful of JavaScript functions.
