Detailed explanation of how to implement the adapter pattern in PHP

<?php
//适配器模式-通过适配器去执行第三方方法
//定义目标接口
interface Target{
  public function simpleMethod1();
  public function simpleMethod2();
}
class Adatee{
  public function simpleMethod1(){
    echo &#39;Adatee simpleMethod1<br/>&#39;;
  }
}
//类适配器模式
class Adapter implements Target{
  private $adatee;
  public function __construct(Adatee $adatee){
    $this->adatee = $adatee;
  }
  public function simpleMethod1(){
    echo $this->adatee->simpleMethod1();
  }
  public function simpleMethod2(){
    echo $this->adatee->simpleMethod12();
  }
}
//客户端接口
class Client{
  public static function main(){
    $adapter = new Adapter(new Adatee());
    $adapter->simpleMethod1();
  }
}
Client::main();
