Debug Class

The Debug class is a simple utility for debugging variables, objects, arrays, etc by outputting information to the display. This is not meant as a one-stop-shop to all of your debugging needs, but as a simple way to throw out information quickly to check things as you go.

dump(*$args)

The dump method outputs multiple mixed values to the browser in a formatted structured way and includes backtrace information so you know where it is coming from.

Static Yes
Parameters Unlimited mixed arguments
Returns void
Example 
Debug::dump($stuff, 'junk', array('whatever'));

By default nested structures will be displayed collapsed to minimize the impact of the output on the page layout. You can alter this behaviour and have it expand by default by setting Debug::$js_toggle_open to true.
