array_column not working for relations

[CC007]

Say I have 2 tables:

bars

+--+---+
|id|bar|
+--+---+

foos

+--+------+---+
|id|bar_id|foo|
+--+------+---+

And in php you have the active record model classes foo and bar.

If you have a belongs_to relation from foo to bar, you can use $foo_var->bar

The problem is that if you have an array of foo objects ($foo_arr), then you are not able to use

array_column($foo_arr, 'bar') to get an array of bar objects.

Workaround:

$bar_arr = array_map(
    function($foo) {
        return $foo->bar;
    },
    $foo_arr
);

Request to fix this issue by making array_column work with php activerecord relations or to provide a function that has the same functionality.
