Includes reusable common processors that can be used on any attribute, even your own. The main idea behind several attributes in this library is to leverage First Class Callables in static expressions ([PHP RFC Wiki](https://wiki.php.net/rfc/fcc_in_const_expr)) introduced in PHP 8.5. FCCs allow you to have attributes whose arguments are not static, but rather resolved during runtime. This removes the clutter of having multiple distinct attributes to cover the same base functionality, for example, validation. Of course, since this approach has its benefits and downsides, this library contains classic attributes with static arguments as well. You are free to use the ones that are the best fit for your use case. ### Libraries that use `constup-foss/php-attributes` [](#libraries-that-use-constup-fossphp-attributes) - - `constup-foss/php-serializer` is a PHP serializer, deserializaer, normalizer and denormalizer library that uses attributes supporting FCCs. The library is currently in active development and is not production-ready.

Many concrete Attribute processors in this library are just extensions of the common ones. Important Common attribute processors can be used on **any** attribute that satisfies supported attribute structure. They can be used on attributes that are not part of this library. You are free to use them on third-party attributes or even on your own attributes. The list of available common attribute processors is avaliable on a separate page: [Common attribute processors](doc/common_attribute_processors.adoc).
