Question

我有一个total_amount（$ total_amount_column），它是那里Amount列的总和。
在数据库中，我有多个按名称调用的条目，它们都有与之关联的金额。

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           |

我需要的是根据总金额列自动计算百分比列。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。我怎么能做到这一点。

Answer 1

这是我最终如何做到的

        <?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

从php中的mysql数据库中的总金额计算百分比
