PHP Customer::isGuest方法代码示例

 /**
  * When the customer is back from PayPal after filling his/her credit card info or credentials, this function is preparing the order
  * PayPal is providing us with the customer info (E-mail address, billing address) and we are trying to find a matching customer in the Shop database.
  * If no customer is found, we create a new one and we simulate a logged customer session.
  * Eventually it will redirect the customer to the "Shipping" step/page of the order process
