Question

我正在尝试将一些JSON我从API响应中添加到电子邮件中，并希望将JSON输出到HTML表中。问题是JSON响应看起来不像我之前使用过的任何东西。

$vs_getClickPath = wp_remote_get('url');
$clickPath_body = wp_remote_retrieve_body( $vs_getClickPath );
$notification['message'] .= $clickPath_body;

这给了我以下内容：

[
  ["date\/time", "page name visited", "city", "region", "country", "company name\/isp", "identity", "search\/referral"],
  ["2016-05-17 10:56:05", "Home Page", "Buffalo", "New York", "United States", "I-evolve Technology Services", "", ""]
]

所有键首先出现在一个数组中，然后出现在另一个数组中。尝试使用索引只是获取单个字符，foreach不起作用。我已尝试json_decode，但它不会输出print_r或var_dump的任何内容。

无论如何，我能够遍历这个并将数据输出到HTML表格中吗？第一个数组是表头，之后的每个数组都是表行。

Answer 1

我使用json_decode($str, true)并返回了一个可以使用的数组：

$str = '[["date\/time","page name visited","city","region","country","company name\/isp","identity","search\/referral"],["2016-05-17 10:56:05","Home Page","Buffalo","New York","United States","I-evolve Technology Services","",""]]';
$json = json_decode($str, true);
echo '<pre>';
print_r($json);

返回

Array
(
    [0] => Array
        (
            [0] => date/time
            [1] => page name visited
            [2] => city
            [3] => region
            [4] => country
            [5] => company name/isp
            [6] => identity
            [7] => search/referral
        )

    [1] => Array
        (
            [0] => 2016-05-17 10:56:05
            [1] => Home Page
            [2] => Buffalo
            [3] => New York
            [4] => United States
            [5] => I-evolve Technology Services
            [6] => 
            [7] => 
        )

)

在true的调用中设置json_decode()会使函数返回一个数组。如果你不想要一个数组，你可以通过将该选项退出呼叫来返回一个对象。

PHP's json_decode()

从输出中，结果是一个数组数组

[ [ "date\/time", "page name visited", "city", "region", "country", "company name\/isp", "identity", "search\/referral" ], [ "2016-05-17 10:56:05", "Home Page", "Buffalo", "New York", "United States", "I-evolve Technology Services", "", "" ] ]

你可以在foreach中找到foreach的值。

foreach ($clickPath_body as $array) { foreach ($array as $string) { echo $string; } echo "<br>"; }

如何使用此JSON响应？
