如何使用列表和數組來實例化類中的字段？

Question

我想在同一時間實例化我的PHP類的每個字段。到目前爲止，我已經嘗試使用list。這是我的代碼下面（這是行不通的）。任何幫助都會很樂意接受。

class Test { 
    private $x; 
    private $y; 
    private $z; 

    public function Test() { 
    $fields = array($this->x, $this->y, $this->z); 
    // I need $fields to be an array here. 
    list($fields) = array(1, 2, 3); // It would work if $fields wasn't an array. 
    echo 'x = ' . $this->x . '<br />y = ' . $this->y . '<br />z = ' . $this->z; 
    } 
} 

new Test(); 

Answer 1

list($this->x, $this->y, $this->z) = array(1, 2, 3);
