Installation and Requirements

Install this library using composer:

$ composer require zendframework/zend-diactoros zendframework/zend-stratigility

Stratigility has the following dependencies (which are managed by Composer):

  • psr/http-message, which provides the interfaces specified in PSR-7, and type-hinted against in this package. In order to use Stratigility, you will need an implementation of PSR-7; one such package is Diactoros.

  • psr/http-server-middleware, which provides the PSR-15 interfaces.

  • zendframework/zend-escaper, used by the ErrorHandler middleware and the (legacy) FinalHandler implementation for escaping error messages prior to passing them to the response.

You can provide your own request and response implementations if desired as long as they implement the PSR-7 HTTP message interfaces.
