<?php

$conn=mysql_connect(&#39;127.0.0.1&#39;,&#39;root&#39;,&#39;&#39;);

mysql_query(&#39;use test&#39;,$conn);
mysql_query(&#39;set names utf8&#39;,$conn);

$perNumber=3; //每页显示的记录数
$page=$_GET[&#39;page&#39;]; //获得当前的页面值
$count=mysql_query("select count(*) from kangbiao"); //获得记录总数
$rs=mysql_fetch_array($count); 
$totalNumber=$rs[0];
$totalPage=ceil($totalNumber/$perNumber); //计算出总页数
if (!isset($page)) {
 $page=1;
} //如果没有值,则赋值1
$startCount=($page-1)*$perNumber; //分页开始,根据此方法计算出开始的记录
$result=mysql_query("select * from kangbiao limit $startCount,$perNumber"); //根据前面的计算出开始的记录和记录数

echo "<table border=&#39;1&#39;>";
echo "<tr>";
echo "<th>id</th>";
echo "<th>name</th>";
echo "<th>age</th>";
echo "<th>grade</td>";
echo "</tr>";
while ($row=mysql_fetch_array($result)) {

echo "<tr>";
 echo "<td>$row[0]</td>"; 
 echo "<td>$row[1]</td>";
 echo "<td>$row[2]</td>";
 echo "<td>$row[3]</td>";  //显示数据库的内容
echo "</tr>";
}
echo "</table>";

if ($page != 1) { //页数不等于1
?>
<a href="02.php?page=<?php echo $page - 1;?>">上一页</a> <!--显示上一页-->
<?php
}
for ($i=1;$i<=$totalPage;$i++) {  //循环显示出页面
?>
<a href="02.php?page=<?php echo $i;?>"><?php echo $i ;?></a>
<?php
}
if ($page<$totalPage) { //如果page小于总页数,显示下一页链接
?>
<a href="02.php?page=<?php echo $page + 1;?>">下一页</a>
<?php
}
