设置类变量，它们是函数中的数组

Question

我有以下代码无法正常工作：

class Tfping extends Worker {
    protected $complete;

    public function __construct($status) {
        $this->complete = $status;
        //print_r($this->complete);
    }

    public function run() {

        $this->complete['result'] = "result";
        print_r($this->complete);
    }

    public function isComplete() {
        return $this->complete;
    }
}

$status['content'] = $row['content'];
$status['id'] = $row['id'];
$status['name'] = $row['name'];
$status['last_up'] = $row['up'];
$status['type'] = "fping";

$pool->submit(new Tfping($status));

我得到的是：

Array
(
    [content] => "content"
    [id] => 24
    [name] => "name"
    [last_up] => 0
    [type] => "type"
)

我的期望是：

Array
(
    [content] => "content"
    [id] => 24
    [name] => "name"
    [last_up] => 0
    [type] => "type"
    [result] => "result"
)

为什么不起作用？如果我做了$ complete ['result'] =“result”; $ this-＆gt;完成= $完成;然后设置变量，但在我的情况下我不能这样做，因为旧的数组值将被覆盖，这不是我想要的。 谢谢您的帮助。
