How do I access an array with objects?

Question

I am trying to learn how to access objects in an array. For example how do I access the name? [name] => Yearly Membership.

Array
(
    [0] => WC_Memberships_User_Membership Object
        (
            [id] => 56325
            [plan_id] => 55119
            [plan] => WC_Memberships_Membership_Plan Object
                (
                    [id] => 55119
                    [name] => Yearly Membership
                    [slug] => yearly-membership
                    [post] => WP_Post Object
                        (

            [renewal_login_token_meta] => _renewal_login_token
        )

)

The function I am using is called: wc_memberships_get_user_active_memberships(); and I set in my code:

$get_user_membership = wc_memberships_get_user_active_memberships(); 

I tried to echo out even just the id

echo $get_user_membership[0]->[id];

But I get an error so I know I am doing something wrong.

How can I access each of these values in this? Any help would be very helpful

edit: here is the error I got in the example of trying to get id

Parse error: syntax error, unexpected '[', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' in (removed filename) on line 325

Answer 1

您可以通过在数组[]和对象{}周围运行来做到这一点，因此：

var_dump($get_user_membership[0]->{'plan'}->{'name'});

Answer 2

我会说：

var_dump($get_user_membership[0]->plan->name);
