Question

之前我已经问了一个类似的问题，但我尝试将其改编为我的代码，但效果不佳。

我有以下代码在PHP中绘制表格，我想在检测到PRODUCT更改时显示PRODUCT总计，我尝试执行以下操作，但它显示了{每个TOTAL开头的{1}}行，并没有很好地累计

变量PRODUCT，GOLD是动态的，即可能有没有NORMAL的表，就像其他没有GOLD的表一样：

这是我的代码：

NORMAL

要查看其工作原理，请复制并粘贴以下页面中的代码：

我希望有人可以帮助我。

可能你正在寻找像这样的东西

    <?
$harvest = Array ( 
     Array ( 
                    'PRODUCT' => 'ROSE' ,
                    'VARIETY' => 'ADELE', 
                    'GOLD' => 160, 
                    'NORMAL' => 0 ,
                    'TOTAL' => 160 
                  ) ,
     Array ( 
                    'PRODUCT' => 'ROSE',

                    'GOLD' => 1320 ,
                    'NORMAL' => 550, 
                    'TOTAL' => 1870
