Elegant money implementation
============================

[](#elegant-money-implementation)

This library provides classes for money manipulation using a pure object-oriented approach.

Yet another PHP-money, why?
---------------------------

[](#yet-another-php-money-why)

Why did we make yet another PHP-library for money? After all, there are:

-
-
-

But, there are disadvantages to using it in pure object-oriented development.

- There are no interfaces — we can't create an object that will represent money itself.
- All existed implementations are classes with hundreds loc and dozens of methods like `add`, `sub`, `divide`, `compare` etc., which are essentially procedural style.
- We can't add new functionality as there are no interfaces, and most implementations are final.
- Eager execution — all calculations happen in construct-time as constructor's arguments should be evaluated.
- Existed libraries hide the scale, the only thing we can control is a rounding method.

Our solution
------------

[](#our-solution)

- We have the `Money` interface! This implementation is not procedural DTO.
- There is no hundreds-lines class with tens of methods. Every operation is an object that implements the `Money` interface.
- Lazy execution: you can construct complex expressions without immediate calculations.
- Explicit scale to avoid ambiguous results.

The presence of the interface allows you to make different classes. For example, you can easily implement `UserBalance`that takes data from a database or some API or even from a file.
