使用php拆分Json编码的数组

事实上，我是Api界的新手，我正在开发一个Api，它使用Curl请求获取并发回数据。获取时，将传递以下信息

{"posts":{"userinfo":{"fullname":"Precious Tom","user_name":"Kendrick","email":"tomprezine@gmail.com","gender":"Male","country":"Nigeria","city":"Port Harcourt","state":"Rivers","year":"1997","month":"9","day":"6"}}}

内容类型：text/html；字符集=UTF-8

http代码：200

拆分阵列似乎是我的问题，如果以前有人问过这个问题，我很抱歉，但是请，我需要你的帮助。 谢谢

更多信息，这里是我的卷曲请求

<?php
session_start();
# data to be sent
$data = array(
'public_key' => 'pk_test_3gc9ffb0hccggf5f3b4e258da848343dff4ae900',
'app_name' => 'Circlepanda',
'app_id' => '2147483647'
);
$curl = curl_init();
# you can also set the url you wanna communicate with by setting
# $curl = curl_init('http://localhost/circlepanda');
  # We post Data
curl_setopt($curl, CURLOPT_POST, 1);
# Set the url path we want to call
 curl_setopt($curl, CURLOPT_URL, 'http://localhost:8888/circlepanda/api/userinfo');
# Make it so the data coming back is put into a string
  curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
  # You can also bunch the above commands into an array if you choose using: curl_setopt_array
# Send the request
$result = curl_exec($curl);
# Get some cURL session information back
$info = curl_getinfo($curl);
echo '<br> content type: ' . $info['content_type'] . '<br>';echo 'http code: ' . $info['http_code'] . '<br>';
# Free up the resources $curl is using
curl_close($curl);
?>

我将传递一个变量，而不是直接数组。 尝试直接数组您的代码运行良好，在传递变量时出错，它停止工作

$city_names = json_decode('{"posts":{"userinfo":{"fullname":"Precious Tom","user_name":"Kendrick","email":"tomprezine@gmail.com","gender":"Male","country":"Nigeria","city":"Port Harcourt","state":"Rivers","year":"1997","month":"9","day":"6"}}}', true);

print_r($city_names);

您有两种选择：

1-使用以下命令将json转换为对象：

2-使用以下命令将json转换为数组：

$arr = json_decode($json, true);
