Question

我已经尝试了implode()，array_column()和其他几个，但由于某种原因，我无法获得正确的输出显示。

简而言之，如何将此数组作为字符串输出？这实际上是一个输出，它将进入表中的行，这是基于API。

代码：

<td><?php
    $desc1 = file_get_contents("https://api.iextrading.com/1.0/stock/market/batch?symbols=$symbol[$x]&types=news&filter=headline");  
    $desc1 = json_decode($desc1,TRUE); 
    foreach($desc1 as $key111 => $des1) {
        echo ($des1['news']);
    }   
?></td>

给定表格行中var_dump()的示例输出：

中的数组到字符串转换

Arrayarray(1) {
    ["news"]=> array(10) { 
        [0]=> array(1) { 
            ["headline"]=> string(92) "Facebook VP says Russian meddling aimed to divide America and it's working 'incredibly well'"
        } 
        [1]=> array(1) { 
            ["headline"]=> string(66) "In wake of indictments, Facebook doubling security staff to 20,000"
        }

Answer 1

每个$ des1中都有一个数组，所以请尝试访问内容，例如：

foreach($desc1['news'] as $key111 => $des1) {
   echo $des1["headline"];
 }

Answer 2

您可以使用array_column，如下所示：

$array = [
    "news" => [ 
        [
            "headline" => "Facebook VP says Russian meddling aimed to divide America and it's working 'incredibly well'",
        ],
        [
            "headline" => "In wake of indictments, Facebook doubling security staff to 20,000"
        ]
    ]
];

echo implode(PHP_EOL, array_column($array['news'], 'headline'));

这是the demo。

当然，在HTML中，您可以使用<br/>代替PHP_EOL，或者根据您的喜好格式化数据。
