php原生数据库分页的代码实例

<?phpheader("Content-type:text/html;charset=utf-8");// 连接数据库$con = mysql_connect("数据库地址","数据库账号","数据库密码");if (!$con){die('Could not connect: ' . mysql_error());} mysql_select_db("数据库名", $con); // 每页显示条数$pageLine = 5; // 计算总记录数$ZongPage = mysql_query("select count(*) from 表名"); // 计算总页数$sum = mysql_fetch_row($ZongPage);$pageCount = ceil($sum[0]/$pageLine);   // 定义页码变量@$tmp = $_GET['page'];  // 计算分页起始值$num = ($tmp - 1) * $pageLine; // 查询语句$result = mysql_query("SELECT 字段 FROM 表名 ORDER BY id DESC LIMIT " . $num . ",$pageLine"); // 遍历输出while($row = mysql_fetch_array($result)) {   echo $row['字段'];   echo "<br/>"; } //分页按钮//上一页$lastpage = $tmp-1;//下一页$nextpage = $tmp+1; //防止翻过界if (@$tmp > $pageCount) {  echo "没有那么多页啦，请返回";} //如果页码大于总页数，则显示没有了if(@$tmp <= 1){  echo "<a href=/"fenye.php?page=$nextpage/">下一页</a>";}else if(@$tmp > 1 && @$tmp < $pageCount){  echo "<a href=/"fenye.php?page=$lastpage/">上一页</a>";  echo "<a href=/"fenye.php?page=$nextpage/">下一页</a>";}else if(@$tmp = $pageCount){  echo "<a href=/"fenye.php?page=$lastpage/">上一页</a>";} // 关闭数据库连接mysql_close($con);?>
