无法访问Json数组响应

Question

嘿我在尝试集成API时遇到API问题...

我有这段代码：

    $deleteOld = $facepp->execute('/person/delete', array('person_name' => $id));
    $response = $facepp->execute('/person/create', array('person_name' => $id));
    print_r($response);
    echo $response['body']['person_id'];

print_r输出

Array
(
    [http_code] => 200
    [request_url] => http://apius.faceplusplus.com//person/create
    [body] => {
    "added_face": 0, 
    "added_group": 0, 
    "person_id": "00c812cbd9c763a6dae36a48bc54b855", 
    "person_name": "3824", 
    "tag": ""
}
)

我想要返回person_id，但我得到的只是＆＃34; {＆＃34;

解决方案：

$response = $facepp->execute('/person/create', array('person_name' => $id));
print_r($response);
$response = json_decode($response['body'], true);
echo $response['person_id'];

Answer 1

你必须使用json_decode（）函数然后它将转换为数组

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));

Answer 2

解决方案：

$response = $facepp->execute('/person/create', array('person_name' => $id));
print_r($response);
$response = json_decode($response['body'], true);
echo $response['person_id'];
