資料庫中，存放文章的表中有「Tag」字段，用來存放標籤。標籤之間以“,”分隔。例如「PHP,VB,隨筆」。
下面的實作程式碼，將標籤從資料庫中搜出來，並格式化處理，使其以出現的次數為依據顯示出不同大小的文字連結。
其中的細節，不做解釋了！
觀念陳、方法笨、效率低的標籤雲的實作程式碼如下：
複製程式碼 程式碼如下:
/**
* WNiaoBlog 標籤範本 ShowTag
*
* @package WNiaoBlog
*
* @subpackage 標籤
*/
//Connect the database
//include('../include/config .php');
/**
* CountTag() - 統計標籤出現的數量，並將資料儲存在兩個陣列中
*
* GetTag() - 從資料庫中存取標籤的標籤
*/

$TagString = $String;
//echo $TagString."
