[Feature] Mapping to camel case

[reinfi]

UseCase

I have a API which I consume and I want to map this to objects.

With PHP8.1 you have the wonderful support of readonly properties.

public readonly string $categoryId;

This works actual perfect with the json mapper and reduces the amount of boilerplate code to near zero.

My problem is, that the API I consume, often uses snake_case names and because of that I have to add setter functions to the model class. This leads to errors because you can not reset the property with a setter if it is a readonly property. There for I have to make it private and add a getter. All the boilerplate code is back.

Suggestion

So my suggestions is to add a new flag to support converting property keys to camelCase if they are not found.

I am not really confident with the naming so I am open for a better naming.

If you are fine with this I would add it to the readme to explain the usage.

See #183:

I would accept a patch that, when $undefinedPropertyHandler returns a string, interprets that string as a property name and then sets the value on it.
The snake case patch here will not be merged.

ah, have not searches all closed pull-requests.

I will change it to your suggestion next week.

Thank your for that patch! I've squashed + merged it.
