FilterIterator implementation that filters files based on a list of suffixes, prefixes, and other exclusion criteria.
You can add this library as a local, per-project dependency to your project using Composer:
composer require phpunit/php-file-iterator
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
composer require --dev phpunit/php-file-iterator
