Swap is a PHP library for currency conversion and exchange rate retrieval, exposing 30+ rate providers behind a single API. It includes PSR-16 caching, historical rates, and a provider fallback chain, and has been maintained since 2014.

Use cases

• convert EUR to USD in a PHP application
• get current exchange rates from multiple providers
• fetch historical exchange rates for a date
• build resilient currency conversion with provider fallback
• cache exchange rate lookups in PHP
• integrate exchange rates into a Laravel or Symfony app
• use free ECB or national bank rate sources

When to choose

• you need exchange rates in PHP from many providers behind one interface
• you want caching and provider fallback built in
• you need historical as well as latest rates
• you want to avoid vendor lock-in to a single rate API

When to avoid

• you need real-time forex trading tick data
• your stack is not PHP
• you need cryptocurrency-only rate conversion without fiat support
