将嵌套在PHP变量中的JSON数据解析

Question

当涉及到PHP时，我是相当中间的，对我来说，使用API是非常新的。手下留情。

我有一个文件，通过API获取一个绑定器的信息。第二个文件更新绑定器。我要做的是，在更新绑定器时，将从JSON响应ID返回的JSON响应中解析绑定器get_binders.php。

我在get_binders.php文件中尝试了以下操作：

$binder_info = $binder_id->binders->binder[0]->id;
foreach ($binder_info as $binder_id){
    echo $binder_id->id;
}

当我使用上面添加的代码运行get_binders.php时，我会得到以下内容：

PHP   2. json_decode($json = ['code' => 'RESPONSE_SUCCESS', 'data' => ['unread_feeds' => 0,
 'binders' => [...]]]) /mnt/e/xampp/htdocs/api_testing/get_binders.php:20 
PHP Notice:  Trying to get property 'binders' of non-object in
 /mnt/e/xampp/htdocs/api_testing/get_binders.php on line 21

我尝试过多种不同的东西。我看过很多帖子。我不知道如何获取绑定器ID并将其传递给一个名为$binder_id的变量，以便在运行update_binder.php时调用它。任何帮助都将不胜感激。

update_binder

<?php

include('create_access_token.php');

$message_text = "This is a new message";

$data = [
    'text' => $message_text
 ];


// turns on php output buffer for debugging
// ob_start();  
// $out = fopen('php://output', 'w');

$data_json = json_encode($data);
$api_url = ''.$site_url.'/v1/'.$binder_id.'/comments?access_token='.$token['access_token'].'';

$ch = curl_init();

// for debugging
// curl_setopt($ch, CURLOPT_VERBOSE, true);  
// curl_setopt($ch, CURLOPT_STDERR, $out);  


// normal curl options
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$binder_data  = curl_exec($ch);

// closes stream and grabs information from output
// fclose($out);  
// $debug = ob_get_clean();

curl_close($ch);
print_r ($binder_data);

// prints debug information
//print_r ($debug);

?>

get_binders.php

<?php

include('create_access_token.php');
include('auth.inc.php');

// for debugging
// var_dump($token);

$tag_value = "Ticket1";

$api_url = ''.$site_url.'/v1/'.$org_id.'/users/'.$email.'/binders?access_token='.$token['access_token'].'&filter=binder&is_email=true&tags_include='.$tag_value.'';

$json_data = file_get_contents($api_url);
$response_data = json_decode($json_data, true);

?>

更新

使用以下内容更新了get_binders.php：

$binder_info = $response_data['data']['binders'][0]['binder'];
echo $binder_info

看看我的代码，我认为$binder_id实际上应该是$response_data。对吗？

当我使用它时，我得到以下信息：

 PHP Notice:  Array to string conversion in /mnt/e/xampp/htdocs/api_testing/get_binders.php on line 18

Answer 1

解析的json返回的是数组而不是对象，因此必须将其用作数组。

因此：

$binder_info = $binder_id['data']['binders'][0]['binder']['id'];

另外，为什么要在$binder_info上运行foreach循环？因为它是一个字符串，它还会给出一个foreach循环错误。

与foreach循环不同，只需：

echo $binder_info，因为它包含id。

更新

要将变量传递给update_binder页面，只需在get_binder页面中初始化一个新变量$binder_id = $binder_id['data']['binders'][0]['binder']['id'];。
