PHP: what is the easiest way to dump class constants into array

Question

I'm having a class with a list of constants. I want something like get_object_vars to dump constants into array. What is the simpliest way to do that?

Thank you in advance!

This will require use of the Reflection class:

function getClassConstants($class) {
    $reflection = new ReflectionClass(
        is_object($class) ? get_class($class) : $class
    );
    return $reflection->getConstants();
}
// usage: $constants = getClassConstants('myClass');
//        $constants = getClassConstants($myClassObjectInstance);

or you can implement it as a method in your class by passing it $this instead of an argument
