Change of a php-script to import order-data from the database

we need to change our php-script to get additional information from our database. The scripts is attached. We can access all data in the lists '[login to view URL]' and '[login to view URL]'. [login to view URL] [login to view URL] But we also need acces to the list 'shoppingCartPaymentEntity' [login to view URL] Especially we need to get access to the string 'additional_data' in that list. In the string the payment-information is given: a:6:{s:14:"component_mode";s:4:"ebay";s:14:"payment_method";s:6:"PayPal";s:16:"channel_order_id";s:26:"181261977472-1313839550008";s:17:"channel_final_fee";d:3.245584;s:12:"transactions";a:1:{i:0;a:4:{s:14:"transaction_id";s:17:"2A5203638D540582A";s:3:"sum";d:37.310000000000002;s:3:"fee";d:1.51;s:16:"transaction_date";s:19:"2015-02-10 18:16:28";}}s:6:"tax_id";s:0:"";} We only need the payment method. In the example above it is "PayPal". Everything else needs to be discarded. So there are 2 tasks: 1. change script so we can access information from list 'shoppingCartPaymentEntity' 2. make sure weonly get the payment method from the whole string 'additional_data'
