How to properly display Chinese characters in PHP?

Simple:

  1. save your source code in UTF-8
  2. output an HTTP header to specify to your browser that it should interpret the page using UTF-8:

    header('Content-Type: text/html; charset=utf-8');
    

Done.

utf8_encode is for converting Latin-1 encoded strings to UTF-8. You don’t need it.
