如何在php中访问外观上的属性

class Facade {
    private $data = array(
        'name' => 'John',
        'age' => 25,
    );

    public function __get($property) {
        if (isset($this->data[$property])) {
            return $this->data[$property];
        } else {
            // 处理属性不存在的情况
            // 可以返回默认值或抛出异常等
        }
    }
}

$facade = new Facade();
echo $facade->name;  // 输出：John
echo $facade->age;   // 输出：25

class Facade {
    private $data = array();

    public function __set($property, $value) {
        // 根据需求进行属性设置操作
        $this->data[$property] = $value;
    }
}

$facade = new Facade();
$facade->name = 'John';
$facade->age = 25;
echo $facade->name;  // 输出：John
echo $facade->age;   // 输出：25
