听前辈说...
听前辈说要在php页面加
header("Content-type: text/html; charset=utf-8");
这个，我加了还是乱码噢 ，
  就这俩个php页面， 还有俩个页面是分页类来的。。

business_form.php
<?php
header("Content-type: text/html; charset=utf-8");
include 'comm.php';
if(isset($_POST['qq'])){
$qq = $_POST['qq'];
$selling_price = $_POST['selling_price'];
$original = $_POST['original'];
$expires = $_POST['expires'];


business_table.php


<?php
include 'paging.php';
 $con =mysql_connect("localhost","root","123456");
 mysql_select_db("business",$con);
 $result = mysql_paging_query("SELECT * FROM business_table", 5);
 echo "<table border='1' height='30' width='480' style=text-align:center>
<tr>
<th>QQ</th>
<th>价格</th>
<th>原价</th>
<th>到期时间</th><th>服务</th>
</tr>";
while($row=mysql_fetch_array($result)){
echo "<tr>";
  echo "<td width='120' height='30' >" . $row['qq'] . "</td>";
  echo "<td width='120' height='30'>" . $row['selling_price'] . "</td>";
  echo "<td width='120' height='30'>" . $row['original'] . "</td>";
  echo "<td width='120' height='30'>" . $row['expires'] . "</td>";
  echo "<td width='120' height='30'>" . $row['diamond']."</td>";
  echo "</tr>";
  }
echo "</table>";
mysql_paging_bar();//显示分页条 下面也来一个
mysql_close($con);

?>


------解决方案--------------------
business_table.php页面 缺少 SET NAMES 'UTF8' 语句
