从流明错误中获取数据

Question

我收到错误“未定义索引：从流明调用数据时的id_currency，请帮帮我

<?php

require '../vendor/autoload.php';
$client = new GuzzleHttp\Client();
$res = $client->request('GET', 'http://139.59.113.86/zeeposapi/public/api/currency', [
'api_token' => ['']
]);

$decodedPosts = json_decode($res->getBody(), true);
?>

<?php
foreach ($decodedPosts as $post)  { ?>
    <tr>
        <th scope="row">
        <?php echo $post['id_currency']; ?>
        </th>
    </tr>
<?php } ?>

Answer 1

错误通知＆＃34; id_currency＆＃34;在数组中不存在。

<强>输出

  

{       ＆＃34;状态＆＃34;：1，       ＆＃34;数据＆＃34;：[           {               ＆＃34; id_currency＆＃34;：1           }，           {               ＆＃34; id_currency＆＃34;：2           }       ]       ＆＃34; totalCount＆＃34;：2   }

您应该使用以下代码

<?php foreach($decodedPosts["data"] as $post) { ?>
    <tr>
        <th scope="row">
        <?php echo $post['id_currency']; ?>
        </th>
    </tr>
<?php } ?>
