推荐答案

作为优秀的编码人员，请在登录时创建session，并在网站范围内使用session.

As good coder create session at login time and use session at website wide.

public function login($username, $password) {
    $user = $this->db
        ->select("username, name, phone")
        ->where(
             [
                'username' => $username,
                'password' => md5($password)
             ]
         )
        ->get("table_name")
        ->row();

   if ($user) {
         $logindata = [
             'userid' => $user->username,
             'name'   => $user->name,
             'phone'  => $user->phone
         ];
         $this->session
              ->set_userdata($logindata);
         return true;
   }
   else {
         return false;
   }
} 

然后您便可以在网站中的任何地方使用

Then after you can use anywhere in website

echo $this->session->userid;
