Debugging of Codeigniter vars

[eluser]mstdmstd[/eluser]
Is it possible in CI 2.2 to show tracing of my vars like calling

Code:

$this->output->enable_profiler(TRUE);

So that my tracing would be shown in this or in similar panel ?

As "similar panel " I mean to write something like this :

Code:

Appfuncs::deb($pricing_id, '$pricing_id::');
Appfuncs::deb($is_insert, '$is_insert::');

And in footer of page to see output of these vars like

Thanks!
