将 JSON 结果放入 php 数组

Question

我有以下数组

Array
(
[responseData] => Array
      (
         [results] => Array
            (

            )

我正在尝试使用 foreach 循环在 php 中解析它，以便显示 url、标题和内容。但是我似乎无法正确解析代码。下面的代码给了我一个“响应数据”无法识别的错误。

foreach($json as value)

echo $value [responsedata];

当我将它留在 echo $value 时，它​​给了我数字 200，这是 responsestatus 的值。当我尝试

foreach( $json =>url => title => content as $value)

它无法识别“=”号。

有什么想法吗？？如果你还没有从帖子中得到 JSON 或 php，我对 JSON 或 php 并不太熟悉:)

TIA

Answer 1

FTR，你发布的是原生数组，不是“json数组”，试试这个：

$rawArray = get_results_somehow();

// Flatten the array to make it easier to work with
$results = $rawArray['responseData']['results'];

foreach ($results as $result) {

    // Should now see the expected values
    var_dump($result);
}

Answer 2

该数据已经是数组形式。您需要像这样迭代 $array['responseData']['results']。

$arr = $array['responseData']['results'];

foreach($arr as $k){
   echo $k['url'];
   echo $k['title'];
   echo $k['content'];
}
