将请求处理到同一PHP SOAP服务器中的多个类

class MySoapService
{
  public function __construct()
  {
     $this->_service1 = new Service1();
     $this->_service2 = new Service2();
  }

  // You could probably use __call() here and intercept any calls,//  thus avoiding the need for these declarations in the wrapper class...

  public function add($a,$b)
  {
     return $this->_service1->add($a,$b);
  }

  public function sub($a,$b)
  {
    return $this->_service2->sub($a,$b);
  }
}

class Service1
{
  public function add($a,$b)
  {
    return $a + $b;
  }
}

class Service2
{
  public function sub($a,$b)
  {
    return $a - $b;
  }
}
