Question

我实际上是Api世界的新手，我正在研究使用卷曲请求获取和发回数据的Api。在获取时，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，如果以前曾经问过这个问题，我很抱歉，但是，我需要你的帮助。感谢。

更多信息，这是我的卷曲请求

<?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Variable而不是一个直接数组。尝试直接数组你的代码运行正常，传递变量毛刺，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);

ANS

Array
(
    [posts] => Array
        (
            [userinfo] => Array
                (
                    [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
                )

        )

)

$city_names = json_decode($json, true);
print $arr['posts']['userinfo']['fullname'];

Answer 2

你有两个选择：

1 - 使用以下内容将json转换为object

$obj = json_decode($json);
print $obj->posts->userinfo->fullname;

2 - 使用以下内容将json转换为array

$arr = json_decode($json, true);
print $arr['posts']['userinfo']['fullname'];

详细了解json_decode

Json编码数组Split使用php
