Chaining Static Methods in PHP?

Question

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)::subtrac         


        

Answer 1

Use PHP 7! If your web provider cannot --> change provider! Don't lock in past.

final class TestClass {
    public static $currentValue;

    public static function toValue($value) {
        self::$currentValue = $value;
        return __CLASS__;
    }

    public static function add($value) {
        self::$currentValue = self::$currentValue + $value;
        return __CLASS__;
    }

    public static function subtract($value) {
        self::$currentValue = self::$currentValue - $value;
        return __CLASS__;
    }

    public static function result() {
        return self::$currentValue;
    }
}

And very simple use:

$value = TestClass::toValue(5)::add(3)::subtract(2)::add(8)::result();

var_dump($value);

Return (or throw error):

int(14)

completed contract.

Rule one: most evolved and maintainable is always better.
