帮我从多维PHP数组中获取一个值

Question

我似乎无法获得这个价值.这是数组:

[1596] => Array
(
    [entry_id] => 1596
    [title] => This is the article title
    [url_title] => url-title-here
    [status] => open
    [entry_date] => 1304544513
    [alt_title] => 
    [article_summary] => This is the article summary
    [article_intro] => This is the article intro
    [article_image] => 
    [article_body] => This is the article body
    [article_media_id] => 1
    [article_videos] => 
    [article_media] => Array
        (
            [0] => Array
                (
                    [row_id] => 3730
                    [row_order] => 0
                    [col_id_7] => image
                    [col_id_12] => right
                    [col_id_8] => 9781400068609.jpg
                    [col_id_9] => 
                    [col_id_10] => 
                    [col_id_54] => 
                )

        )

)

我正在尝试使用构建URL

'http://www.domain.com/uploads/media/'.$entry['entry_id']['article_media'][0]['col_id_8']

但它在图像值的末尾不断给我一个'1'.它应该是9781400068609.jpg,对吗？我有什么不对？

['entry_id']正在使你的道路脱轨。您需要通过其编号（可能在变量中）引用顶级键，如下所示：

$entry_id = 1596;
$valueYouWant = $entry[$entry_id]['article_media'][0]['col_id_8'];
