How correctly command PHP write how to fwrite this string into .json file

 <?php
 fwrite($ip = $handle,
 {
    "en": {
        "Basics": {
        "search": "en/search"
        }
      }
    }       
 );
 ?>

I was trying to program PHP to help search engine discover a new page created and view the page.
All I need to do is write this last string.
