Chaining Static Methods in PHP?

Is it possible to chain static methods together using a static class? Say I wanted to do something like this:
$value = TestClass::toValue(5)::add(3)::subtract(2)::add(8)::result();
. . . and obviously I would want $value to be assigned the number 14. Is this possible? | 0 | [
