Question

我的数组如下：

我想将此数组提取为表格形式：

 Array
(
[0] => Array
    (
        [product_id] => 19
        [attributes] => Array
            (
                [0] => Array
                    (
                        [label] => Hard Disk
                        [name] => harddisk
                        [value] => 500 GB
                    )

                [1] => Array
                    (
                        [label] => RAM
                        [name] => ram
                        [value] => 16 GB
                    )

                [2] => Array
                    (
                        [label] => Graphics
                        [name] => graphics
                        [value] => 2 GB
                    )

                [3] => Array
                    (
                        [label] => Graphics Card
                        [name] => graphicscard
                        [value] => 2 GB
                    )

            )

    )

[1] => Array
    (
        [product_id] => 20
        [attributes] => Array
            (
                [0] => Array
                    (
                        [label] => Hard Disk
                        [name] => harddisk
                        [value] => 1 TB
                    )

                [1] => Array
                    (
                        [label] => RAM
                        [name] => ram
                        [value] => 8 GB
                    )

                [2] => Array
                    (
                        [label] => Graphics
                        [name] => graphics
                        [value] => 1 GB
                    )

                [3] => Array
                    (
                        [label] => Graphics Card
                        [name] => graphicscard
                        [value] => 1 GB
                    )

            )

    )

 )

可能会出现另一个产品ID，因为它是动态的。我能够获得第一列，但如何获得其他列。我的代码是：

  Product ID      |  19           |   20
  Hard Disk       |  500 GB       |   1 TB
  RAM             |  16 GB        |   8 GB
  Graphics        |  2 GB         |   1 GB
  Graphics Card   |  2 GB         |   1 GB

我总是对HTML和PHP的混合感到困惑。我更喜欢更清晰的外观。

我会分两步解决你的问题：

1：将数组转换为可以轻松呈现为表格的数组。

2：从该数组中渲染表格。

if (is_array($all)) {

  // step 1: create table
  foreach ($all as $one) {
    $id = $one['product_id'];
    $table['Product Id'][$id] = $id;
    foreach ($one['attributes'] as $attribute) {
      $label = $attribute['label'];
      $value = $attribute['value'];
      $table[$label][$id] = $value;
    }
  }

  // step 2: render the table
  echo '<table class="table">'.PHP_EOL;
  foreach ($table as $label => $row) {
    echo "<tr><td>$label</td>";
    foreach ($table['Product Id'] as $id) {
      echo '<td>'.(isset($row[$id]) ? $row[$id] : '-').'</td>';
    }
    echo '</tr>'.PHP_EOL;
  }
  echo '</table>'.PHP_EOL;

}

此例程可以处理缺少的属性。

此代码并不完美，但它为您提供了一个重点。挑战是进一步降低复杂性。我认为这是可能的。
