$limit=20; // 每頁顯示的行數  
$numresults=mysql_query("select * from TABLE where YOUR CONDITIONAL HERE order by WHATEVER");//換成你所需要的sql語句 >
// next determine if offset has been passed to script, if not use 0

$offset=1;> // 得到查詢結果  
$result=mysql_query("select id,name,phone ".

// 現在顯示查詢結果  
while ($data=mysql_fetch_array($result)) {  
// 在這裡插入您要顯示的結果以及樣式  
🎜>// 顯示器按鈕  

if ($offset！=1) { // bypass PREV link if offset is 1

}  

// 計算頁數
