How to check if enum type?

Question

How can I tell if a variable is of type enum?

I have installed PHP 8.1 on my Ubuntu 20.04. I'm testing the new "enum" types.

Is something like that possible?

is_enum($var)
gettype($var) === 'enum'

Answer 1

Someone told me the solution:

if ($var instanceof \UnitEnum) {
   echo 'is enum';
}
