Question

我有一个从付款网关返回到woocommerce的数组作为订单注释。我需要访问它才能获得价值。

数组是这样的：

    Array
(
[0] => WP_Comment Object
    (
        [comment_ID] => 149
        [comment_post_ID] => 1686
        [comment_author] => 
        [comment_author_email] => 
        [comment_author_url] =>

        [comment_date] => 2019-01-24 14:30:31
        [comment_date_gmt] => 2019-01-24 12:30:31
        [comment_content] => Payment done, Return data: Array

            )

    )

如何获取[txId]键的值？

我尝试过：

$array[0]->comment_content->txId;
$array[0]->comment_content['txId'];

我要读到[comment_content]，但如何输入

:Payment done, Return data: Array
(

}

Answer 1

编辑我的答案。您的comment_content是字符串而不是数组。因此，您根本不必访问它，在它下面有另一个嵌套数组。

$array[0][0]['txId'];

您的方法也用于对象而不是数组。

Answer 2

根据您显示给我们的输出，comment_content是字符串，而不是结构。您可以使用txId例如{p>从中提取preg_match的值

preg_match('/\[txId\] => ([a-f0-9-]+)/', $array[0]->comment_content, $matches);
echo $matches[1];

输出：

edf3354c-af38-49f7-810a-e79234e6604d

您可能应该研究如何创建该元素，以便它可以是结构而不是字符串，这将使您的生活更加轻松。
