php - 数组作为类变量，在类中的构造中设置

Question

有没有办法将数组传递给类/对象构造并访问/返回或操作它？

代码：

$affiliates = array(
        "clickbank" => "clickbankdata",
        "meepbank" => array(
                "meepbankdata" => "meep"
        )
);
class Affiliate {
    public $affiliates = array();

    public function __construct($array) {
        $this->affiliates = $array;
    }

    public function getAffiliatesArray() {
        return $this->$affiliates;
    }
}

$main = new Affiliate($affiliates);
print_r($main->getAffiliatesArray());

Answer 1

   public function getAffiliatesArray() {
            return $this->$affiliates;
        }

   should be

  public function getAffiliatesArray() {
        return $this->affiliates;
    }

Answer 2

代替

return $this->$affiliates;
              ^
              |-------- Remove This 

和

return $this->affiliates;
