Interface 는 클래스의 설계 도면을 만든다고 보면 된다.

 

<?php
interface Paymentinterface{
    public function payNow();
}

interface LoginInterface{
    public function LoginFirst();
}

class Paypal implements PaymentInterface,LoginInterface{
    public function loginFirst(){}
    public function payNow(){}
    public function paymentProcess(){
        $this->loginFirst();
        $this->payNow();
    }
}
class BankTransfer implements PaymentInterface,LoginInterface{
    public function loginFirst(){}
    public function payNow(){}
    public function paymentProcess(){
        $this->loginFirst();
        $this->payNow();
    }
}
class Visa implements PaymentInterface{
    public function payNow(){}
    public function paymentProcess(){
        $this->PayNow();
    }
}
class Cash implements PaymentInterface{
    public function payNow(){}
    public function paymentProcess(){
        $this->PayNow();
    }
}
class BuyProduct{
    public function pay(PaymentInterface $paymentType){
        $paymentType->paymentProcess();
    }
    public function onlinePay(LoginInterface $paymentType){
        $paymentType->paymentProcess();
    }
}

$paymentType=new Cash();
$buyProduct=new BuyProduct();
$buyProduct->pay($paymentType);


?>
