I have the following response and I was wanting to know how can I turn it into an multidimensional array foreach item [0][1] etc

Controller $rece Response:

array(16) { ["digital_delivery"]=> int(1) ["original_referrer"]=> string(11) "No Referrer" ["shop_rule_us_state_code"]=> string(1) "0" ["subtotal_ex_vat"]=> string(4) "9.99" ["subtotal_inc_vat"]=> string(4) "9.99" ["tax_amount"]=> string(4) "0.00" ["delivery_price"]=> string(4) "0.00" ["discount_deduction"]=> string(4) "0.00" ["currency_code"]=> string(3) "GBP" ["total"]=> string(4) "9.99" ["paid"]=> int(1) ["created"]=> string(19) "2013-10-31 21:03:44" ["website_id"]=> string(2) "64" ["first_name"]=> string(3) "Joe" ["last_name"]=> string(5) "Blogs" ["email"]=> string(17) "[email protected]" } array(16) { ["digital_delivery"]=> int(1) ["original_referrer"]=> string(11) "No Referrer" ["shop_rule_us_state_code"]=> string(1) "0" ["subtotal_ex_vat"]=> string(4) "9.99" ["subtotal_inc_vat"]=> string(4) "9.99" ["tax_amount"]=> string(4) "0.00" ["delivery_price"]=> string(4) "0.00" ["discount_deduction"]=> string(4) "0.00" ["currency_code"]=> string(3) "GBP" ["total"]=> string(4) "9.99" ["paid"]=> int(1) ["created"]=> string(19) "2013-10-31 21:03:44" ["website_id"]=> string(2) "64" ["first_name"]=> string(3) "Joe" ["last_name"]=> string(5) "Blogs" ["email"]=> string(13) "[email protected]" } array(16) { ["digital_delivery"]=> int(1) ["original_referrer"]=> string(11) "No Referrer" ["shop_rule_us_state_code"]=> string(1) "0" ["subtotal_ex_vat"]=> string(4) "9.99" ["subtotal_inc_vat"]=> string(4) "9.99" ["tax_amount"]=> string(4) "0.00" ["delivery_price"]=> string(4) "0.00" ["discount_deduction"]=> string(4) "0.00" ["currency_code"]=> string(3) "GBP" ["total"]=> string(4) "9.99" ["paid"]=> int(1) ["created"]=> string(19) "2013-10-31 21:03:44" ["website_id"]=> string(2) "64" ["first_name"]=> string(3) "Joe" ["last_name"]=> string(5) "Blogs" ["email"]=> string(15) "[email protected]" }
