复制代码 代码如下:
$link = mysql_connect('localhost', 'root', '') or die(mysql_error());
mysql_select_db('vote', $link) or die(mysql_error());
mysql_query("set names utf8");
$num = 3;
$url = "page.php";
$con = "

";
$page = (isset($_REQUEST['page'])) ? $_REQUEST['page'] : 1;
$offset = ($page - 1) * $num;
$result = mysql_query("SELECT COUNT(*) FROM client");
$total = mysql_fetch_row($result);
$total = $total[0];
$pagenum = ceil($total / $num);
$page = min($pagenum, $page); //获得首页
$prepg = $page - 1; //上一页
if ($prepg <= 1)
$prepg = 1;
$nextpg = ($page == $pagenum ? 1 : $page + 1); //下一页
//如果只有一页则跳出函数：
if ($pagenum <= 1)
return false;
$sql = "SELECt `name`,`content` FROM `client` LIMIT " . $offset . "," . $num;
$res = mysql_query($sql);
while ($content = mysql_fetch_row($res)) {
$con .= "
• $content[0]:  $content[1]
";
}
$con .= "

";
$con .= <<< PAGE

首页|上一页|下一页|尾页

PAGE;
echo $con;
?>
