Installation

To install Peso, first select the desired integration lib, then the desired service lib, like so:

composer require peso/peso peso/ecb-service php-http/discovery guzzlehttp/guzzle symfony/cache

In this example

• peso/peso is a simple wrapper over Peso services for standalone use

• peso/ecb-service is a service provider for the European Central Bank

• ECB service dependencies, same for all HTTP integrations:

  • php-http/discovery is a HTTP client autoconfigure package. It is not required, you can configure the client manually.

  • guzzlehttp/guzzle is a HTTP client known to php-http/discovery. Any client supporting PSR-18 would do.

  • symfony/cache a cache library if you need caching. (recommended)

• Alpha series: 0.1.x, … 0.8.x. Unstable to use
