我是靠谱客的博主俭朴自行车，最近开发中收集的这篇文章主要介绍PHP+MySQL实现输入页码跳转到指定页面功能示例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

本文实例讲述了PHP+MySQL实现输入页码跳转到指定页面功能。分享给大家供大家参考，具体如下：

一、代码

conn.php：

<?php
$id=mysql_connect("localhost","root","root")or dir('连接失败' . mysql_error());
if(mysql_select_db("db_database13",$id))
echo "";
else
echo ('连接失败' . mysql_error());
mysql_query("set names gb2312");
?>

index.php：

<?php session_start();include("conn/conn.php"); if ($_GET['page']=="") {$_GET['page']=1;};?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>查询结果的分页显示</title>
<style type="text/css">
<!--
.STYLE1 {font-size: 12px}
.STYLE2 {font-size: 13px}
a:link {
 text-decoration: none;
}
a:visited {
 text-decoration: none;
}
a:hover {
 text-decoration: none;
}
a:active {
 text-decoration: none;
}
-->
</style>
</head>
<script language="javascript">
 function chk(form){
 if(form.page.value<=0||form.page.value>form.pages.value){
 alert("您输入的页码无效!!");
 form.page.focus();
 return(false);
 }
 return(true);
 }
</script>
<body>
<table width="500" border="0" cellpadding="0" cellspacing="1" bgcolor="#11DFF0">
 <tr>
 <td width="100" height="25" align="center" bgcolor="#11DFF0" class="STYLE2">姓名</td>
 <td width="100" align="center" bgcolor="#11DFF0" class="STYLE2">编号</td>
 <td width="125" align="center" bgcolor="#11DFF0" class="STYLE2">电话</td>
 <td width="175" align="center" bgcolor="#11DFF0" class="STYLE2">地址</td>
 </tr>
 <?php
 if($_GET['page']){
 $page_size=3;
 $query="select count(*) as total from tb_insert";
 $result=mysql_query($query);
 $message_count=mysql_result($result,0,"total");
 $page_count=ceil($message_count/$page_size);
 $offset=($_GET['page']-1)*$page_size;
 $query="select * from tb_insert where id order by id desc limit $offset, $page_size";
 $result=mysql_query($query);
 while ($myrow=@mysql_fetch_array($result)){
 ?>
 <tr>
 <td height="25" align="center" bgcolor="#FFFFFF"><span class="STYLE2"><?php echo $myrow[name];?></span></td>
 <td align="center" bgcolor="#FFFFFF"><span class="STYLE2"><?php echo $myrow[number];?></span></td>
 <td align="center" bgcolor="#FFFFFF"><span class="STYLE2"><?php echo $myrow[tel];?></span></td>
 <td align="center" bgcolor="#FFFFFF"><span class="STYLE2"><?php echo $myrow[address];?></span></td>
 </tr>
 <?php }}?>
</table>
<form name="form1" method="get" action="index.php" onSubmit="return chk(this)">
<table width="500" border="1" cellpadding="0" cellspacing="0" bgcolor="#11DFF0">
 <tr>
 <td width="42%" align="center" valign="middle"><span class="STYLE1">&nbsp;&nbsp;页次：<?php echo $_GET['page'];?>
 / <?php echo $page_count;?> 页 记录：<?php echo $message_count;?> 条 </span></td>
 <td width="58%" height="28" align="left" valign="middle"><span class="STYLE1"> &nbsp;分页：
 <?php
 if($_GET['page']!=1)
 {
 echo "<a href=index.php?page=1>首页</a>&nbsp;";
 echo "<a href=index.php?page=".($_GET['page']-1).">上一页</a>&nbsp;";
 }
 if($_GET['page']<$page_count)
 {
 echo "<a href=index.php?page=".($_GET['page']+1).">下一页</a>&nbsp;";
 echo "<a href=index.php?page=".$page_count.">尾页</a>";
 if($_GET['page']<= $page_count and $_GET['page']>0)
 {
 echo "<a href=index.php?page=".$_GET['page']."></a>";
 }
 }
 ?>
 <input name="page" type="text" size="3">
 <input type="hidden" name="pages" value="<?php echo $page_count;?>">
 <input type="submit" name="Submit" value="跳转">
 </span> </td>
 </tr>
 </table>
</form>
</body>
</html>
