Show PHP object complete

This line: $this->promotions_helper->promotion->rs_auto[0]

When I click in $this, xdebug return this:

$this (object) = 
$this->QTYcheck_promotion (object) = 
$this->check_num (string) = 349132
$this->check_promotion (object) = 
$this->final_date (null) = 
$this->inicial_date (null) = 
$this->message (null) = 
$this->orders_drinks_can (object) = 
$this->orders_drinks_have (object) = 
$this->orders_foods_can (object) = 
$this->orders_foods_have (object) = 
$this->promo_num (string) = 21
$this->promotions_helper (object) = 
$this->split_num (int) = 0

When I click in promotions_helper, promotions, etc... returns nothing.

My problem is: I want see, what is inside promotions_helper and promotion... but this Plugin show just the 'first layer'.
