Brick\Money is a high-quality, immutable PHP library for representing monetary values, performing arithmetic, currency conversion, allocation, and locale-aware formatting. It provides exact arithmetic via brick/math, supports multiple contexts (default, cash rounding, custom scale, auto-scale), and includes a rich set of exchange rate providers (configurable, PDO-backed, cached, chained, base-currency derived). The library features a strategy pattern for allocation (five algorithms including Hamilton's method) and cross-currency comparison. It is thoroughly tested, type-safe, and follows modern PHP practices (PHP 8.2+, readonly classes, enums, sealed interfaces). The codebase demonstrates strong software craftsmanship with clean abstractions, immutable value objects, and well-isolated components. It is actively maintained with regular releases and comprehensive documentation.
Laravel Exchange Rates is a Laravel package that provides a unified interface for interacting with multiple exchange rate APIs. It implements a driver pattern to support Exchange Rates API, Exchange Rates Data API, Exchange Rate Host, and CurrencyBeacon. The package allows developers to get current and historical exchange rates, convert currencies between different denominations, and cache results to minimize API calls. Architecture follows Laravel conventions with service providers, facades, and a Manager-based driver system. The SharedDriverLogicHandler component demonstrates strong abstraction skills by eliminating code duplication across API drivers while maintaining clean separation of concerns.
