[FIXED] How to install PSR-7 http-message interfaces with Composer

Issue

Is there maybe a way to install the PSR-7 HTTP message interfaces using Composer? I can't seem to find any information on the official github page, nor on the web.

Beeing a Composer-beginner, I would also like to ask, if it is possible to install packages from internet (maybe also outside Github) with Composer, even if they don't provide informations regarding installation using Composer.

Thank you very much.

Solution

You just have to select and install a PSR-7 implementation like laminas/laminas-diactoros or slim/psr7. You can find all composer packages on https://packagist.org/.

Example:

composer require slim/psr7
