Exchange PHP secure from github

I need an exchange that the project comes from github, can be peatio or ccxt or any other that you feel comfortable to develop (preferably in php), and extra functions for each user as: objective (this goal has a title like Buy a bike , every month I put some dollars in bitcoin, an internal calculation will estimate the time in which I will have the full money of the objective based on the valorization of the bitcoin last year), other functionalities will be included with the passage of time and the same developer who initiated the project will be listed as the main option
