Since	2.0
Source	framework/helpers/VarDumper.php

VarDumper is intended to replace the buggy PHP function var_dump and print_r.

It can correctly identify the recursively referenced objects in a complex object structure. It also has a recursive depth control to avoid indefinite recursive display of some peculiar variables.

VarDumper can be used as follows,

VarDumper::dump($var);
