How would I format the following into a php array?
{ "merchant_ref": "Astonishing-Sale", "transaction_type": "authorize", "method": "credit_card", "amount": "1299", "currency_code": "USD", "credit_card": { "type": "visa", "cardholder_name": "John Smith", "card_number": "4788250000028291", "exp_date": "1020", "cvv": "123" } }
