PHP简单实用的数据分页显示代码
index.php代码
02.include_once("config.php");
03.require_once('page.class.php'); //分页类
04.$showrow = 10; //一页显示的行数
05.$curpage = empty($_GET['page']) ? 1 : $_GET['page']; //当前的页,还应该处理非数字的情况
06.$url = "?page={page}"; //分页地址，如果有检索条件 ="?page={page}&q=".$_GET['q']
07.//省略了链接mysql的代码，测试时自行添加
08.$sql = "SELECT * FROM userinfo";
09.$total = mysql_num_rows(mysql_query($sql)); //记录总条数
10.if (!empty($_GET['page']) && $total != 0 && $curpage > ceil($total / $showrow))
11. $curpage = ceil($total_rows / $showrow); //当前页数大于最后页数，取最后一页
12.//获取数据
13.$sql .= " LIMIT " . ($curpage - 1) * $showrow . ",$showrow;";
14.$query = mysql_query($sql);
