I just added a new feature in the Nix PHP builder that will create the proper PHP environment based on the `composer.json` file. That feature is a work in progress, but works pretty fine already.Basically, the idea is to read the `composer.json`, extract the required extensions and instantiate a PHP environment containing those extensions.Inferring the adequate PHP version to use could be a nice to have.Find the code and examples at: https://github.com/loophp/nix-php-composer-builder/#extra-work-in-progress https://mathstodon.xyz/@Pol/110841976414167056
