We normally list the available options, and if there are too many we at least provide a prefix for the error eg. MYSQLI_BLAH_X

I thought about that too, but there isn't any common pattern between them. One of the values doesn't even have a corresponding constants.

That seems kinda bad that one of the options doesn't have a constant?

As future scope, would it make sense to have an Enum of MySQLi options? As that would make the type checking and value validation easy.

Yes, it is. Maybe we should add the constant. Enums would definitely be better but it would be a breaking change difficult for cross-version compatibilty.

It would be possible to assign the enum case as the constant value, or support int|Enum. But I think already adding the missing constant is the big thing.
