Question

我将此代码用于循环：

<?php foreach($_SESSION['accessories'] as $accessory) : ?>

    <?php var_dump($accessory); ?>

<?php endforeach; ?>

问题是，现在我可以访问每个附件的内容，但不知道该附件的ID，因为原始数组看起来像这样：

[accessories] => Array
    (
        [63] => Array
            (
                [price] => 15000
                [name] => Product 2
            )

        .
        ..
        ...

    )

63失去了;（

任何想法如何获得63？

Answer 1

您需要在foreach循环中添加$ key

<?php foreach($_SESSION['accessories'] as $key => $accessory) : ?> 
<?php var_dump($accessory); ?> 
<?php endforeach; ?>

这将给出你正在寻找的关键63 ..

Answer 2

<?php foreach($_SESSION['accessories'] as $key => $accessory) : 

    echo $key;                 // prints id 63
    echo $accessory['price'];  // prints price
    echo $accessory['name'];   // prints names 

   endforeach; ?>

php中的foreach删除了密钥
