web system created with CodeIgniter that incorporated into Ideone

Well I tell them I work on my title project in creating a web system with CodeIgniter. The idea is to attach a part of the web system with an online compiler that could be Ideone.

I have the wording of a exercise and I schedule the solution in C language and sending the solution should be compiled by a compiler online not visible on that interface but if from behind and return if the solution is correct or not.

If anyone has worked with CodeIgniter or Ideone or has knowledge on the subject could suggest to me or give some idea how to find a solution to theme to investigate and make the solution. Thank You
