适配器模式（PHP实现）

//目标角色  
interface Target {  
    public function simpleMethod1();  
    public function simpleMethod2();  
}  
  
//源角色  
class Adaptee {  
      
    public function simpleMethod1(){  
        echo ‘Adapter simpleMethod1‘."<br>";  
    }  
}  
  
//类适配器角色  
class Adapter implements Target {  
    private $adaptee;  
      
      
    function __construct(Adaptee $adaptee) {  
        $this->adaptee = $adaptee;   
    }  
      
    //委派调用Adaptee的sampleMethod1方法  
    public function simpleMethod1(){  
        echo $this->adaptee->simpleMethod1();  
    }  
      
    public function simpleMethod2(){  
        echo ‘Adapter simpleMethod2‘."<br>";     
    }   
      
}  
  
//客户端  
class Client {  
      
    public static function main() {  
        $adaptee = new Adaptee();  
        $adapter = new Adapter($adaptee);  
        $adapter->simpleMethod1();  
        $adapter->simpleMethod2();   
    }  
}  
  
Client::main();
