Answer 1

使用您在此处发布的JSON字符串，您需要首先使用json_decode()对其进行解码。假设没有设置任何标志，这将解码为JSON字符串中表示的对象和数组的混合。

$str = '{"token": "ey...WTg",
"user": {
...
}
}'; //The JSON string you posted in the question
$request = json_decode($str);

从那里到user_id的路径是：

$request->order[0]->addon_categories[0]->user_id  // 4

Answer 2

使用foreach循环。

假设您已将数组存储在变量$array中。

代码：

foreach($array as $arr)
{
if($arr['user_id'] == 4)
{
$user = $arr; 
}
}

您将获得user_id为4的整个对象，您可以通过获得相关列

$user_id = $user['user_id];

希望这会有用。
