製作變量的HTML表格列表月度快照

Question

下表列出了username由total降序。我如何使第一列中列出的$date上每個行列表中具有最高total的人列出？

$query = "SELECT username, datesubmitted, COUNT(1) AS total 
    FROM submission 
    GROUP BY username 

ORDER BY total DESC" 

$result = mysql_query($query); 

$date = strtotime("January 1, 2010"); 

$arr = array(); 

echo "<table>"; 
    while ($row = mysql_fetch_array($result)) { 

    $date = strtotime("+1 month", $date); 

      echo '<tr>'; 
      echo '<td >'.date("F j, Y", $date).'</td>'; 
      echo '<td >'.stripslashes($row["username"]).'</a></td>'; 
      echo '<td >'.number_format(($row["total"])).'</td>'; 
      echo '</tr>'; 
} 

echo "</table>";

你可以在MySQL的分組爲好，沒有必要指望在PHP中：

SELECT count(*), username, datesubmitted 
    FROM submission 
    GROUP BY username, month(datesubmitted)
