Failed to get an object property that containing “:protected” [duplicate]

What is the difference between public, private, and protected? (17 answers)

Closed 6 years ago.

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

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

Object output

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

Anyone know what wrong with my code? Thanks.

回答1:

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.

Read up on OOP access modifiers.
