The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
Earning an online degree from a school can likely lead to a promotion and/or salary raise, or prepare you for a new career. Even if classroom training may be considered more traditional, online education is advantageous in its own right. There is a mixture of degree programs, and individual classes offered through online learning organizations. It is not unheard of for tuition costs for online courses to be lower than that of a conventional school, although this is certainly not reliable of all online programs.
