Validation groups name best practice

[michnaadam33]

Are there any good practices for 'validation groups' name style?
I see that in documentation in some case we have Default (ucfirst) and in the other registration (strtolower).
What about multiple word name. Should it be a camelaCase or PascalCase?

Thank you for answer

This is a good question ... let's ask @xabbuh and @wouterj which would be their "best practice" to name validation groups. Thanks!

By default, Symfony has a Default validation group and a ClassName (e.g. User) validation group.

I haven't used this feature ever in an application, but I would say it's better to not use PascalCase for custom groups - to differentiate between the ClassName groups and custom groups. I'm leaning towards under_scored, but that's 100% personal preference :)

I agree with Wouter.
