实现翻页跳转功能

$limit=25;
if (!empty($start)) $start=0;
if (!empty($s)) $s=0;

mysql_connect("localhost","","");
mysql_select_db(database);

//统计数据库记录总数
$result=mysql_query("select * from table");
$num=mysql_numrows($result);

$result=mysql_query("select * from table order by id limit $start,$limit");
$numb=mysql_numrows($result);
echo "

";
if (!empty($numb)) {
for($i=0;$i $val=mysql_result($result,$i,"val");
$val1=mysql_result($result,$i,"val1");
echo "";
}
}
echo "

$val

$val1

";

//数字循环翻页的控制
echo "

";
echo "";

//前翻控制
if ($s>20) {
if ($s==21) {
$st=$s-21;
} else {
$st=$s-20;
}
$pstart=$st*$limit;
echo "

";
}
echo "";

//设置当前页对应页数无链接功能
$star=$start;

//注意循环的初始附值,仔细想想为什么不是 0
for ($page=$s;$page

$start=$page*$limit;
echo "

";

//控制数字页面限制显示功能,控制只显示 20 页
if ($page>0 && ($page%20)==0) {
if ($s==0) {
$s=$s+21;
} else {
$s=$s+20;
}

$start=$start+$limit;

if ((($num/$limit)-1)>$page) {
echo "

";
}
//注意跳出循环的控制
break;
}
}
echo "

页:

echo "start=$pstart&s=$st>prve

>>

"; if($page!=$star/$limit) { echo " echo "start=$start&s=$s>"; } echo $page; if($page!=$star/$limit) { echo ""; } echo "

echo "start=$start&s=$s>next

";
?>

以上的程已序可以完成强大的循环翻页功能
