php json解码具有多个对象数组的对象

Question

我无法获得这个json数组的值...我怎么能单独拥有所有这些值!!

{
    "id": "jai",
    "pwd": "123",
    "user": [
        {
            "fname": "jai",
            "lname": "gupta"
        },
        {
            "fname": "sameer",
            "lname": "seth"
        }
    ],
    "college": "vit"
}

Answer 1

$myArray = json_decode($json, true);

var_dump($myArray['id']);
var_dump($myArray['user'][0]['fname']);

Answer 2

您可以通过访问常规的php数组键值对来访问每个“值”。

$jsonn = '{"id":"jai","pwd":"123","user":[{"fname":"jai","lname":"gupta"},{"fname":"sameer","lname":"seth"}],"college":"vit"}';
$new = json_decode($jsonn, true);

$id = $new['id'];
$user = $new['user'];
..... and so on.

希望这有帮助。

干杯！

Answer 3

您可以将这些值从json解码为object。

$result = json_decode('{"id":"jai","pwd":"123","user":[{"fname":"jai","lname":"gupta"},{"fname":"sameer","lname":"seth"}],"college":"vit"}');

和如下所述：

$result->id; 
$result->pwd;
