本文執行個體講述了PHP+MySQL實現輸入頁碼跳轉到指定頁面功能。分享給大家供大家參考，具體如下：
一、代碼
conn.php：
<?php$id=mysql_connect("localhost","root","root")or dir('串連失敗' . mysql_error());if(mysql_select_db("db_database13",$id))echo "";elseecho ('串連失敗' . 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>查詢結果的分頁顯示</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("您輸入的頁碼無效!!"); 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">編號</td> <td width="125" align="center" bgcolor="#11DFF0" class="STYLE2">電話</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"> 頁次：<?php echo $_GET;?> / <?php echo $page_count;?> 頁 記錄：<?php echo $message_count;?> 條 </span></td> <td width="58%" height="28" align="left" valign="middle"><span class="STYLE1"> 分頁： <?php if($_GET['page']!=1) { echo "<a href=index.php?page=1>首頁</a> "; echo "<a href=index.php?page=".($_GET['page']-1).">上一頁</a> "; } if($_GET['page']<$page_count) { echo "<a href=index.php?page=".($_GET['page']+1).">下一頁</a> "; echo "<a href=index.php?page=".$page_count.">尾頁</a>"; if($_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="跳轉"> </span> </td> </tr> </table></form></body></html>
