PHP 分页类,比较简单实用的分页代码。
复制代码 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 == '') $page = 1; if($page >= $page_count) $page = $page_count; $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> "; $pagenav .= "<a href='?page=$pre_page'>前一页</a> "; $pagenav .= "<a href='?page=$next_page'>后一页</a> "; $pagenav .= "<a href='?page=$page_count'>末页</a>"; $pagenav.=" 跳到<select name='topage' size='1' onchange='window.location=\"?page=\"+this.value'>\n"; for($i=1;$i<=$page_count;$i++){ if($i==$page) $pagenav.="<option value='$i' selected>$i</option>\n"; else $pagenav.="<option value='$i'>$i</option>\n"; } } // 使用示例 if (!$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; ?>
