Oihana PHP Enums

FilterOption uses ConstantsTrait

Defines constants representing valid option keys for PHP's filter functions (e.g. {@see filter_var()}, {@see filter_input()}).

This class provides a type-safe alternative to using raw string keys such as 'flags', 'options', 'min_range', and 'max_range' when specifying filter options. Using constants reduces typos and improves code completion.

The ConstantsTrait allows you to retrieve these constants dynamically, for example to validate option names or iterate over all possible values.
