debugConsole is a powerful debug system for PHP that maintains by Andreas Demmer. It's written completely in PHP and work as a class, not like Xdebug, which is an extension to PHP. With debugConsole, error handling and variable change tracking is taken care of.

Editor Comment:

If the native variable dump function in debugConsole are as good as dBug , this might be the tool of choice for all developers.
