Question

我正在尝试创建一个页面，显示来自网页上的mysql数据库的rpg排名

我进入数据库并按级别组织数据，因此首先显示最高级别的人，依此类推，但数据库不包含排名表

我试图在Dreamweaver中手动执行此操作，但我不知道如何创建计数器并将其显示在表格中？

我设法得到以下内容： http://slayersgaming.com/rpgranks2.php

<?php
$dbh=mysql_connect("********", "**********", "*********") or die('Cannot connect to the database because: '. mysql_error());
mysql_select_db("C368969_thcrpgCSGO");

$rpgranks_sql = "SELECT * FROM `thc_rpg` ORDER BY `thc_rpg`.`level` DESC LIMIT 0, 30 ";

$rpgranks_query = mysql_query($rpgranks_sql) or die(mysql_error());

$rsrpgranks = mysql_fetch_assoc($rpgranks_query);


?>

实际上这很容易做到。你只需要在你的do-while循环中使用一个计数器：

<?php
$counter = 1;
do{
?>
<table width="501" height="58" border="0">
  <tr>
    <td><?php echo $counter; ?></td>
    <td width="240"><?php echo $rsrpgranks['name'];?></td>
    <td width="70"><?php echo $rsrpgranks['level'];?></td>
    <td width="70"><?php echo $rsrpgranks['xp'];?></td>
    <td width="70"><?php echo $rsrpgranks['credits'];?></td>
    <td width="70">&nbsp;</td>
  </tr>
</table>
<?php
    $counter++;
} while ($rsrpgranks = mysql_fetch_assoc($rpgranks_query))
?>

尝试在网页中打印数据库，但无法获得表格的计数器
