基於一個特定的字段對php表進行排序

嗨，我試圖根據$ fratio對這個表進行排序。具有最高美元值的人將被置於表中的第一位。下面是我到目前爲止工作的代碼 - 你可以嘗試使用基於一個特定的字段對php表進行排序

ORDER BY kills/deaths DESC

所以完整的查詢看起來像

SELECT `UserID`,`Playername`,`Kills`,`Deaths` FROM users ORDER BY kills/deaths DESC LIMIT 0,50

而且完整的代碼看起來像這樣

// MySQL connection. 
$connection = mysql_connect($host,$username,$password); 
@mysql_select_db($database) or die("Unable to select database. Be sure the databasename exists and online is."); 
$query="SELECT `UserID`,`Playername`,`Kills`,`Deaths` FROM users LIMIT 0,50"; 
$query = mysql_query($query); 

echo('<table width="300" border="2" cellspacing="3" cellpadding="3"> 
<tr> 
    <td style="min-width:150px;">Playername:</td> 
    <td style="width:100px">Kills:</td> 
    <td style="width:100px">Deaths:</td> 
    <td style="width:100px">Ratio:</td> 
</tr>'); 
while($row = mysql_fetch_assoc($query)) 
{ 
$id = $row['UserID']; 
$playername = $row['Playername']; 
$kills = $row['Kills']; 
$deaths = $row['Deaths']; 
$ratio = ($kills/$deaths); 
$fratio = ceil($ratio); 

echo(' 
    <tr> 
    <td style="min-width:150px;"><a href="stats.php?id='.$id.'">'.$playername.'</a></td> 
    <td style="width:100px">'.$kills.'</td> 
    <td style="width:100px">'.$deaths.'</td> 
    <td style="width:100px">'.$fratio.'</td> 
    </tr>'); 
    } 
    echo('</table>'); 

    mysql_close($connection); 
    ?>

$playername = $row['Playername']; 
$kills = $row['Kills']; 
$deaths = $row['Deaths']; 
$ratio = ($kills/$deaths); 
$fratio = ceil($ratio); 

echo(' 
    <tr> 
    <td style="min-width:150px;"><a href="stats.php?id='.$id.'">'.$playername.'</a></td> 
    <td style="width:100px">'.$kills.'</td> 
    <td style="width:100px">'.$deaths.'</td> 
    <td style="width:100px">'.$fratio.'</td> 
    </tr>'); 
    } 
    echo('</table>'); 

    mysql_close($connection); 
    ?>

以下是「ORDER BY」的示例。你應該考慮閱讀至少這個來得到它的主要想法。

u能烏拉圭回合的建議.. – Swayam 2012-01-06 05:34:12

是的，當然提供的編碼。用SQL查詢編輯評論。我希望你知道該把它放在哪裏:) – MJA 2012-01-06 05:36:26

我是一個PHP新手！ Ur建議的完整編碼版本會很棒！ :) – Swayam 2012-01-06 05:47:24

你會在mysql這樣的比例：

ORDER BY CEILING(kills/deaths) DESC
