无法获得包含“:protected"的对象属性. [英] Failed to get an object property that containing ":protected"

问题描述

我使用下面的代码获取了对象的属性_items:protected，但是没有运气.

I used the code below to get the object's property _items:protected, but no luck.

$obj = JSite::getMenu();
print_r($obj->_items:protected);

对象输出

JMenuSite Object
(
    [_items:protected] => Array
        (
            [101] => stdClass Object
                (
                    [id] => 101
                    [menutype] => mainmenu

有人知道我的代码有什么问题吗?谢谢.

Anyone know what wrong with my code? Thanks.

推荐答案

您正试图从类外部访问受保护的属性. 只能从类本身或从该类继承的类内部访问受保护的属性.

You are trying to access a protected property from outside the class. A protected property can only be accessed from within the class itself or classes that inherit from that class.

阅读OOP访问修饰符.
