我是PHP编程的新手，目前我试图将Xenforo forum与我的网站集成。我想用XenAPI plugin来集成注册系统。我遵循这个页面的指南，它工作!
示例请求:
api.php?action=register&hash=d8e8fca2dc0f896fd7cb4cb0031ba249&username=Contex&password=My_Password&email=me@contex.me
响应是:

"remember_key": "11d20c2e9ffbbd7466a872dacf18051a47d94dce"
}
这是我的问题，如何转换响应之一为PHP变量?
From "user_group_id": 2 to $user_group_id = 2 .
新问题
我从Hassaan那里得到了答案，我遵照他的指示，
我编辑我的php脚本如下:
$response = file_get_contents('http://forum.mydomain.com/api.php?action=getUsers&value=Contex&hash=Contex:9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08');
$response = json_decode($response, true);
echo $response->user_id;
然后我测试它，得到一个新的错误信息。
Notice: Trying to get property of non-object.
如何修复?谢谢!
您需要使用json_decode()
$response = json_decode($str);
$user_group_id = $response->user_group_id;
echo $user_group_id;
注释用API响应变量替换$str
试例
$str = <<<JSON

JSON;
$response = json_decode($str);
$user_group_id = $response->user_group_id;
echo $user_group_id;
