What happens is very simple ... Your ajax is sending the id and in your PHP controller you change the variable. But to see the change in your HTML you have to "refresh" the page to change the IDs using the php variable as you do ... What you can do is use JS to inject the new IDs that you receive from AJAX.

funcion success(response){
  for(int i = 0, i < response.length; i++){
      $("div[id="+response[i].anterior+"]).attr("id",response.nuevo);
  }
}

Something like that I imagine myself ... So you change the IDs dynamically. You can not change them directly with PHP, remember that when you load the page, that $ row ['userID'] is painted but once it is painted it is static, not dynamic.
