Generating REST documentation in a Codeigniter project
In past projects I have used http://apidocjs.com/ which I find pretty easy to use and straightforward to generate from in multiple environments. It took me like 15-20 minutes to get going and looking how I wanted with it having npm already installed. This one doesn't really care about directory or code structure, just your supplied info in the doc blocks.
You Can use https://github.com/manish29ify/codeigniter3-restapi-with-swagger Still it is under development but you can use Swagger with PHP rest server very easily
