太阳成游戏网站

请教一下，下面代码错在哪？

// 查询会员id为2的会员组id--gid，再得到会员组的名称和devices信息

$v = \Phpcmf\Service::M()->table('member_group_index')->where('uid', 2)->getAll();

$data = \Phpcmf\Service::M()->table('member_group')->where('id', $v['gid'])->getAll();

//遍历数组

foreach ($data as $t) {

$return[] = [

'name' => $t['name'],

'devices' => $t['devices'],

];

}
