A metapackage for PHP that installs the polyfills you need, and removes those that are redundant.
Add the polyphill-php to your project like this:
composer require 'empaphy/polyphill-php:^1'This metapackage makes clever use of composer dependencies to ensure that the Symfony polyfill packages are installed only for the exact PHP versions that you need. This reduces the footprint of your vendor directory.
Since polyphill is a metapackage it doesn't take up any actual space in your vendor directory itself.
