PHP分页代码

PHP分页代码如下：

<?PHP

// pager类

$page = $_GET;

function pager($rows,$page_size){

global $page,$select_from,$select_limit,$pagenav;

$page_count = ceil($rows/$page_size);

if($page <= 1 || $page == '') $page = 1;        //PHP分页代码

if($page >= $page_count) $page = $page_count;    //PHP分页代码

$select_limit = $page_size;

$select_from = ($page - 1) * $page_size.',';

$pre_page = ($page == 1)? 1 : $page - 1;

$next_page= ($page == $page_count)? $page_count : $page + 1 ;

$pagenav .= "第 $page/$page_count 页 共 $rows 条记录 ";

$pagenav .= "<a href='?page=1'>首页</a> ";        //PHP分页代码

$pagenav .= "<a href='?page=$pre_page'>前一页</a> ";    //PHP分页代码

$pagenav .= "<a href='?page=$next_page'>后一页</a> ";   // PHP分页代码

$pagenav .= "<a href='?page=$page_count'>末页</a>";    //PHP分页代码

$pagenav.="跳到<select name='topage' size='1' onchange='window.location="?page="+this.value'>n";

for($i=1;$i<=$page_count;$i++){

if($i==$page) $pagenav.="<option value='$i' selected>$i</option>n";

else $pagenav.="<option value='$i'>$i</option>n";

}

}

// PHP分页代码使用示例

if (!$conn= MysqL_connect("localhost","root","root")) die('数据库选择失败！');

if (!MysqL_select_db("test",$conn)) die('数据库选择失败！');

MysqL_query('set names GBK');

///////////////////////////// 利用pager函数计算出 $select_from 从哪条记录开始检索、$pagenav 输出PHP分页导航

$rows = MysqL_num_rows(MysqL_query("select * from test"));

pager($rows,2);

$sql = "select * from test limit $select_from $select_limit";

$rst = MysqL_query($sql);

while ($row = MysqL_fetch_array($rst)){

echo "$row[id] - $row[sex] - $row[name] <hr />";

}

echo $pagenav;

?>
