如何在php中自动知道数组字段的名称？

Question

我只是有一个小问题,我找不到任何答案,因为我不确切知道如何在Google上制定它.

所以我从查询中返回了这个数组:

Array
(
    [0] => Array
        (
            [aad3177ec0cbced7a15fae003bdd0ff3] => Array
                (
                    [rowid] => aad3177ec0cbced7a15fae003bdd0ff3
                    [id] => 21
                    [qty] => 1
                    [price] => 176
                    [name] => KRUPS YY1305 
                    [image] => utilities/images/products/p2070396dt.jpg
                    [description] => Menu simplifié pour une convivialité optimale.   
                    [subtotal] => 176
                )
        )
)

我想得到所有信息rowid,id,qty ...通过另一个变量的foreach循环存储它而不知道第二个数组的名称:'aad3177ec0cbced7a15fae003bdd0ff3'.我只想在用户注销时从存储在数据库中的购物车中检索文章.

那我该怎么说呢:

echo $myArray['0'][theNumberGoesHereAutomatically]['price'];

理想情况下,我的代码看起来像这样:

foreach ($data2 as $cart){
            $data = array(
                   'rowid'      => $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['rowid'],
                   'id'         => $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['id'],
                   'qty'        => $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['qty'],
                   'price'      => $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['price'],
                   'name'       => $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['name'],
                   'image'      => $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['image'],
                   'description'=> $cart_unserialized[$token]['aad3177ec0cbced7a15fae003bdd0ff3']['description'],
                );
            $this->cart->insert($data2);
            $token++;
        };

不知道aad3177ec0cbced7a15fae003bdd0ff3.

有任何想法吗？谢谢 :)

您可以通过以下方式轻松完成:

foreach ($data2 as $varname => $cart){

$varname将包含aad3177ec0cbced7a15fae003bdd0ff3.
