请考虑以下代码:

final class TinkerWithMe {
    protected $key1 = 19;
    private $key2 = 88;
}

$class = new TinkerWithMe();

$getKeys = function() {
    return array($this->key1, $this->key2);
};

$oldKeys = $getKeys->call($class);

$newKey1 = 96;
$newKey2 = 42;

$setKeys = function() use ($newKey1, $newKey2) {
    $this->key1 = $newKey1;
    $this->key2 = $newKey2;
};

$setKeys->call($class);

当您可以通过闭包或反射轻松解决问题时,为什么还要考虑OOP的可见性？

有没有办法阻止我失踪的这种事情？
