enums in codeigniter 4 ?

I need to create enums on codeigniter 4.3.7 site (not in database) for passing enum as parameter to custom function...
In which way can I do ?

Thanks in advance!

Use PHP 8.1 or later.
Create an ENUM file and put it in somewhere where PSR-4 autoloader can autoload.

Any possible decision for php 8.0 ?

Enum is the new feature in PHP 8.1.

You cannot use it with PHP 8.0.

Some external libraries supporting 8.0 too ?

Use class with properties as alternative?
