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);
