Perhaps not as clean and easy as the functionality being built-in, but it gets the job done.

I would suggest to use the built-in functionality then. enum cases are literally just class constants, thus you can access them via the constant() function or the dynamic class constant fetch syntax for PHP 8.3+ and check their existence with defined(): https://3v4l.org/44goe

    <?php

    enum ExampleEnum
    {
        case ONE;
        case TWO;
        case THREE;
    }

    $caseName = 'ONE';
    var_dump(defined(ExampleEnum::class . "::{$caseName}"));
    var_dump(constant(ExampleEnum::class . "::{$caseName}"));
    var_dump(ExampleEnum::{$caseName});

Outputs:

    bool(true)
    enum(ExampleEnum::ONE)
    enum(ExampleEnum::ONE)
