PHP实现对mysql数据库内容分页显示

<?php $conn=mysql_connect('127.0.0.1','root','');mysql_query('use test',$conn);mysql_query('set names utf8',$conn);$perNumber=3; //每页显示的记录数$page=$_GET['page']; //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='1'>";echo "<tr>";echo "<th>id</th>";echo "<th>name</th>";echo "<th>age</th>";echo "<th>grade";echo "</th>
</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 "";if ($page != 1) { //页数不等于1?><a href="02.php?page=<?php%20echo%20%24page%20-%201;?>">上一页</a> <!--显示上一页--><?php }for ($i=1;$i<=$totalPage;$i++) {  //循环显示出页面?><a href="02.php?page=<?php%20echo%20%24i;?>"><?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%20echo%20%24page%20+%201;?>">下一页</a><?php } ?>
