Question

我使用这个php代码（部分）在我的函数中生成了一个数组：

while (!$combined->EOF) {
        $orders_id = $combined->fields['orders_id'];
        $customers_name = $combined->fields['customers_name'];
        $products_name = $combined->fields['products_name'];
        $products_model = $combined->fields['products_model'];
        $products_quantity = $combined->fields['products_quantity'];

        $this_order_data = array(
                           'orders_id' => $orders_id,
                           'name' => $products_name,
                           'model' => $products_model,
                           'quantity' => $products_quantity,
                           );

        if (isset($this->timeframe[$id]['combined'][$oID])) {
            $this->timeframe[$id]['combined'][$oID]['products'][] = $this_order_data;
        } else {
            $this->timeframe[$id]['combined'][$oID]['order_id'] = $oID;
            $this->timeframe[$id]['combined'][$oID]['customer_name'] = $customers_name;  
            $this->timeframe[$id]['combined'][$oID]['products'][] = $this_order_data;
        }
$combined->MoveNext();
}

这给出了一个类似于以下示例的数组：

[6] => Array
    (
        [order_id] => 1910
        [customer_name] => Customer A
        [products] => Array
            (
                [0] => Array
                    (
                        [orders_id] => 1910
                        [name] => Product 1
                        [model] => P1
                        [quantity] => 31
                    )

                [1] => Array
                    (
                        [orders_id] => 1910
                        [name] => Product 2
                        [model] => P2
                        [quantity] => 50
                    )

                [2] => Array
                    (
                        [orders_id] => 1910
                        [name] => Product 3
                        [model] => P3
                        [quantity] => 20
                    )

            )

    )

[7] => Array
    (
        [order_id] => 1911
        [customer_name] => Customer B
        [products] => Array
            (
                [0] => Array
                    (
                        [orders_id] => 1911
                        [name] => Product 2
                        [model] => P2
                        [quantity] => 75
                    )

                [1] => Array
                    (
                        [orders_id] => 1911
                        [name] => Product 4
                        [model] => P4
                        [quantity] => 30
                    )

            )

    )

然后我使用此代码输出代码以便在屏幕上显示

<?php
      $i = 0;
      foreach($timeframe['combined'] as $key => $c_data) if ($c_data['order_id'] == $c_data['products'][$i]['orders_id']){
      $items = count($c_data['products']);
?>
   <tr class="lineItemRow" <?php echo $rollover; ?>>
                        <td class="lineItemContent" align="left"><?php echo $c_data['products'][$i]['name']; ?></td>
   <td class="lineItemContent" align="left"><?php echo $c_data['products'][$i]['model']; ?></td>
   <td class="lineItemContent" align="right"><?php echo $c_data['products'][$i]['quantity']; ?></td>
   <td class="lineItemContent" align="right"><?php echo $c_data['products'][$i]['count']; ?></td>
   </tr>
  <?php 
  if ($i == $items){
      $i= 0;
  }else{
      $i=$i+1;
  }
}

因为我不知道每个阵列中会有多少产品，所以我认为我需要获得$ c_data ['products']的计数，在循环开始之前将$ i设置为0，然后每次递增，直到达到计数值。只有它不能那样工作。我注意到的是，$ i只会在每次移动到新订单时递增，而不是每个新产品。这显然给了我不正确的数据，因为$ i每次都没有查看数组的正确部分。

我应该如何正确地遍历'products'数组中的每个项目？

为什么你不循环进入$ c_data ['products']？

<?php

foreach($timeframe['combined'] as $key => $c_data)
    foreach($c_data as $data)
       foreach($data['products'] as $product)
          if ($data['order_id'] == $product['orders_id']) { ?>

        <tr class="lineItemRow" <?php echo $rollover; ?>>
            <td class="lineItemContent" align="left"><?php echo 
            $product['name']; ?></td>
            <td class="lineItemContent" align="left"><?php echo 
            $product['model']; ?></td>
            <td class="lineItemContent" align="right"><?php echo 
            $product['quantity']; ?></td>
            <td class="lineItemContent" align="right"><?php echo 
            $product['count']; ?></td>
         </tr>

<?php } ?>

当我遍历它时，php多维数组输出显示不正确的产品
