Checkboxe Values

I want to use a checkbox where members can select several options. Say there are 5 options and a member chooses 1,2 and 3
What value appears in the database: The equivalent of the binary 11100 = 7? or is there some other way they are stored?

Thanks
Phil

Hello

It will be JSON encoded value. Something like ["Option1", "Option2", "Option3"]
