//返回有顺序的客户id
        $customer_ids = $customer->bespeakTime($uid);
        $res = Customer::with('customer_industry', 'zone1', 'zone2', 'department', 'user.agent', 'tag', 'contact', 'source');
        $res->whereIn('id', $customer_ids)
            ->where('is_call', '>=', 0)
            ->orderByRaw(DB::raw("FIND_IN_SET(id, '" . implode(',', $customer_ids) . "'" . ')'));//按照指定顺序排序
 
这里$customer_ids是一个一维数组，所以在里面要转化一下  然后在根据相应的值来排序
