How can we store protected array values in php variables - php

Question

I am trying to access a protected array tree. I had tried many ways to get the data from the tree. The array is stored in a variable called $printers. I had tried a normal approach like using array index values like echo $printers[0].printers etc, but no luck. Could anyone please guide me to how to access this protected array tree?
