From object to associative array

Export object properties as array: get_object_vars()

The function get_object_vars() extracts properties or attributes from an object and creates an array with attribute names as keys and attribute values as values.

For example, if you have an object with 4 properties

class Person
{
    public string $name;
    public string $surname;
    public int $age;
    private bool $active = true;
}

$person = new Person();
$person->name = "John";
$person->surname = "Doe";
$person->age = 42;

print_r(get_object_vars($person));
/*
Array
(
    [name] => John
    [surname] => Doe
    [age] => 42
)
*/

If the property of an object is private the property will not be exported by the function get_object_vars() because of the scope. In the example look at the property $active that is declared as private. It is initialised as true but it is not exported in the array.
