先贴张图看看效果
在贴一下代码吧
<?php
$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 "<p>PHP分页代码的小模块</p>";
echo "<table border=1 cellspacing=0 WIDTH=60% align=center>";
echo "<tr><td>ID</td><td>NAME</td></tr>";
while($row = mysql_fetch_assoc($result)){
$id = $row['id'];
$name = $row['name'];
echo "<tr><td>".$id."</td><td>".$name."</td></tr>";
}
echo "</table>";
//上一页 、下一页
$pageprev = $page -1 ;
if($page > $total){
$pagenext = $total;
} else{
$pagenext = $page +1;
}
// 做链接 跳转;
echo "<h3> <a href='page.php?p={$pageprev}'>上一页</a> 丨<a href='page.php?p={$pagenext}'>下一页</a></h3>";
mysql_free_result($result);
mysql_close($conn);
?>
关键点:
1、
$sql = "select * from page order by id limit {$offset},{$pagesize}";
2、
echo "<h3> <a href='page.php?p={$pageprev}'>上一页</a> 丨<a href='page.php?p={$pagenext}'>下一页</a></h3>";
这两点是关键能体现 分页技术 和php 代码艺术的地方~
