new to using paypal, how do i unscramble the response to use it (array)

Hi

I have the following back from a test account on paypal (to my thanks screen) that I need to show to the screen once I have assigned all the values so I can use them further.

How can I assign all these details?  such as $address_status = "Confirmed";

Received in POST:
