Question

我的代码如下：

<?php        
    $items = array(
        array("SKU" => "a49w8dsa", "Title" => "Socks", "Description" => "Sports socks", "Price" => "1.50", "Quantity" => "4"),
        array("SKU" => "ta8dla", "Title" => "T-shirt", "Description" => "ABC Brand undershirt", "Price" => "14.25", "Quantity" => "2"),
        array("SKU" => "yusa982", "Title" => "Flip Flips", "Description" => "XYZ Brand Beach Flops", "Price" => "2.88", "Quantity" => "5"),
        array("SKU" => "gnbaiue", "Title" => "Ball Cap", "Description" => "No Name", "Price" => "3.58", "Quantity" => "1"),
        array("SKU" => "ythwq836", "Title" => "Frizbee", "Description" => "Whammo Frisbee Disc", "Price" => "2.47", "Quantity" => "2")
    );
?>

 <?php if (count($items) > 0): ?>
       <table>
          <thead>
            <tr>
              <th><?php echo implode('</th><th>', array_keys(current($items))); ?></th>
            </tr>
          </thead>
          <tbody>
     <?php foreach ($items as $row): array_map('htmlentities', $row); ?>
            <tr>
              <td><?php echo implode('</td><td>', $row); ?></td>
            </tr>
     <?php endforeach; ?>
          </tbody>
        </table>
      <?php endif; ?>






<?php 

    $final = array_shift($items);
foreach (array_column as $key => &$value){
 $value += array_sum(array_row($Price . $Quantity));
  }

 unset($value);

  var_dump($final);
    ?>

我想获取每个项目的价格，将其乘以该数组中的数量并将总和添加到变量中，然后打印。我在这方面有点新，所以借口我的代码！

Answer 1

将每个项目的价格合并到一个数组中，然后最后使用array_sum() -

进行总结

$eachPrice = array();
foreach ($items as $key => $val) {
  $eachPrice[] = $val['Price'] * $val['Quantity'];
}

$totalPrice = array_sum($eachPrice);

var_dump($totalPrice); // should be total price of all items

将每个数组项的两个键值相乘
