I've got a question for those experienced in PHP about coding style.
I've done a few functions lately that I've given names like GetVariable() and CountUsers(). At least to me, they looked better than get_variable, and count_users.
However, looking newly at classes and object oriented programming in general, I'm noticing that capital lettors seemed to be reserved for those tasks.
Is there an accepted standard for nomenclature for PHP?
I would pose the same question to db table names, such as in MySQL. I've got tables names like User with a primary key of UserID.
