文档的注释PHP发布数据并返回JSON

Question

I have two questions actually:

1. For some functions I am posting forms to them, can I mention them as @params in comments or what:

   /* some descriptions 
    *
    * @param string userName
    */
   
   
   
   public function add(){ 
              $userName = $_POST['user']
           ......
   }
   

2. From some function I am returning data as JSON, how to mention JSON as return type and format:

    /* some descriptions 
     *
     * @return JSON [{id, name,...}]
     */
   

Answer 1

You can write anything you like in comments. That said, it's not a conventional use - @param and @return should describe the actual parameters and return values of the function in question. See e.g. the draft PHP-FIG recommendation for what's (mostly) conventional.

If you're returning a JSON string it would be better to document it as

@return string Text here describing what is being returned

since as far as PHP is concerned it's just another string.
