How to make a share content system with codeigniter framework?

I will make a share content(share posts or news in facebook,twitter,google+,pdf,…)with the codeigniter framework
how can I do it?

That’s too big a question to be answered here. There are extensive docs on CodeIgnitor, and they are very well written, so I’d suggest you learn how to use it first. The, when it’s done, make a site for it, or post it on GitHub, and get suggestions from the community on how to improve it. :slight_smile:
