Title Body

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? Update : It doesn't work (you can't return "self" - it's not an instance!), but this is where my thoughts have taken me: class TestClass { public static $currentValue; public static function toValue($value) { self::$currentValue = $value; } public static function add($value) { self::$currentValue = self::$currentValue + $value; return self; } public static function subtract($value) { self::$currentValue = self::$currentValue - $value; return self; } public static function result() { return self::$value; } } After working that out, I think it would just make more sense to simply work with a class instance rather than trying to chain static function calls (which doesn't look possible, unless the above example could be tweaked somehow).
