實作「上一頁」與「下一頁按鈕_PHP教學課程

//此範例摘自phpbuilder.com  
//稍加翻譯  
//  

$limit=20; // 每頁顯示的行數  
$numresults=mysql_query("select * from TABLE where YOUR CONDITIONAL HERE order by WHATEVER");//換成你所需要的sql語句 >
// next determine if offset has been passed to script, if not use 0  
if (empty($offset)) {  
$offset=1;> // 得到查詢結果  
$result=mysql_query("select id,name,phone ".  
"from TABLE where YOUR CONDITIONAL HERE ".  
"order by WHATEVER limit" $

// 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  
$prevoffset=$offset-20; "$PHP_SELF?offset=$prevoffset">上一頁   n";  
}  

// 計算頁數  
$pages=intval($numrows/$limit);

// $pages now contains int of pages needed unless there is a remainder from division  
if ($numrows%$limit) {  
// has remainder so pages ;  
}  

for ($i=1;$i$newoffset=$limit*($i-1) ;  
print "$i   n";  
}  

// check to see if last page if (!(($offset/$limit)==$pages) && $pages!=1) {  
// not last page so give NEXT link  
$newoffset=$offset $limit;  
print "下一頁

n";  
}
