I am trying to make the Restful API documentation in PHP swagger, what I did before is that I changed the JSON to work out, now I know we can make the JSON by making PHP files and using swagger notation. I did check the Pet.php example and I get the code but I don't know how to execute the file to get the JSON API documentation which I can link with my Swagger UI. I read the documentation but it is so confusing and I don't know how to get through this problem can anyone help, please? Here is the link I study but to no worth.

Can anyone tell me step-by-step how to generate the API documentation in JSON? I will be very thankful to him thanks.
