$localhost = "localhost"; $username = "root"; $password = "root"; $db = "test"; //信息 $pagesize = 5; $conn = mysql_connect($localhost,$username,$password); //链接数据库 if(!$conn){ echo "数据库链接失败".mysql_error(); } mysql_query("SET NAMES 'UTF8'"); //编码转化 $db_select = mysql_select_db($db); //选择表 //查询记录总数 $total_sql = "select COUNT(*) from page"; $total_result = mysql_query($total_sql); $total_row_arr = mysql_fetch_row($total_result); $total_row = $total_row_arr[0]; //总条数 //总页数 $total = ceil($total_row / $pagesize); //当前页数 $page = @$_GET['p'] ? $_GET['p'] : 1; //limit 下限 $offset = ($page - 1)*$pagesize;
$sql = "select * from page order by id limit {$offset},{$pagesize}"; $result = mysql_query($sql); echo " PHP分页代码的小模块 ";echo "
//上一页 、下一页 $pageprev = $page -1 ; if($page > $total){ $pagenext = $total; } else{ $pagenext = $page +1; } // 做链接 跳转; echo " 上一页 丨下一页";
mysql_free_result($result); mysql_close($conn); ?> |
关键点:
1、

1 |
$sql = "select * from page order by id limit {$offset},{$pagesize}"; |

代码如下:
echo "

这两点是关键能体现 分页技术 和php 代码艺术的地方~
