我有一个 total_amount ($total_amount_column)，它是下方 Amount 列的总和。
在数据库中，我有多个按名称调用的条目，它们都有一个与之关联的数量。

所以它在名为“envelope_sub”的表中看起来像这样

name         |amount          |percentage

House        |1550.00         |

Electricity  |400.00          |

Internet     |50.00           |

我需要的是根据总量和列自动计算百分比列。所以换句话说，我需要每个条目的百分比并将它们自动插入数据库中各自的百分比字段中。请问我怎样才能做到这一点。

这就是我最终做到的方式

        <?php 
    $query = "SELECT * from stats where user_id='".$nameID."' $where order by week desc";
        $result = mysql_query($query) or die(mysql_error());

        $worked_week = mysql_num_rows($result);  

      if(mysql_num_rows($result)) {
        $k = 1;
        while ($row_stats = mysql_fetch_array($result)) 
        {   

     // Total Section //
     $total_worked_hours=$total_worked_hours+$row_stats['worked_hours'];
     $total_sales=$total_sales+$row_stats['sales'];
     $total_sales=number_format($total_sales,2,'.','');
     $total_facials=$total_facials+$row_stats['facials'];
     $total_double_facials=$total_double_facials+$row_stats['double_facials'];
     $total_classes=$total_classes+$row_stats['classes'];
     $total_faces_viewed=$total_faces_viewed+$row_stats['faces_viewed'];
     $total_interviews=$total_interviews+$row_stats['interviews'];
     $total_recruits=$total_recruits+$row_stats['recruits'];

    ///

     $k++;
     }

 // Percentage Section //
$perc_worked_hours = $total_worked_hours / $worked_week;
$perc_sales = $total_sales / $worked_week;
$perc_facials = $total_facials / $worked_week;
$perc_double_facials = $total_double_facials / $worked_week;
$perc_classes = $total_classes / $worked_week;
$perc_faces_viewed = $total_faces_viewed / $worked_week;
$perc_interviews = $total_interviews / $worked_week;
$perc_recruits = $total_recruits / $worked_week;
// round up
$perc_worked_hours=number_format($perc_worked_hours,0,'.','');
$perc_sales=number_format($perc_sales,2,'.','');
$perc_facials=number_format($perc_facials,0,'.','');
$perc_double_facials=number_format($perc_double_facials,0,'.','');
$perc_classes=number_format($perc_classes,0,'.','');
$perc_faces_viewed=number_format($perc_faces_viewed,0,'.','');
$perc_interviews=number_format($perc_interviews,0,'.','');
$perc_recruits=number_format($perc_recruits,0,'.','');
// END
