将PHP对象转换为关联数组

class Person {
    public $name;
    public $age;
    public $gender;

    public function __construct($name, $age, $gender) {
        $this->name = $name;
        $this->age = $age;
        $this->gender = $gender;
    }
}

$person = new Person("John Doe", 25, "Male");
$array = get_object_vars($person);

print_r($array);

Array
(
    [name] => John Doe
    [age] => 25
    [gender] => Male
)
