無法使用php登錄

Question

我正在使用PHP CodeIgniter框架。 這裏是login.php控制器。

public function index() 
     { 
      if($this->input->post('login') == 1) 
      { 
       $user = new Users_model(); 
       $user->email = $this->input->post('email'); 

       $user->password = $this->input->post('password'); 

       $user->user_role = $this->input->post('user_role'); 
       $results = $this->usermodel->login($user); 

       if(count($results)>0) 
       { 
        if(is_array($results) || is_object($results)) 
        { 
         foreach($results as $row) 
         { 
          $session_array = array(
           "id" => $row['id'], 
           "username" => $row['username'], 
           "email" => $row['email'], 
           "password" => $row['password'], 
           "image" => $row['image'], 
           "description" => $row['description'], 
           "account_status" => $row['account_status'], 
           "user_role" => $row['user_role'] 
           ); 
          $this->session->set_userdata($session_array); 
          $url = base_url() . "home?login=success"; 
          redirect($url, "refresh"); 
         } 
        } 
       }else{ 
        $url = base_url() . "login?login=failed"; 
        redirect($url, "refresh"); 
       } 
      }else{ 
       $this->load->view('login-page'); 
      } 
     } 

這裏是模型中的Users_model.php。

function login($user){ 
     $conditions = array(
     "email" => $user->email, 
     // "password" => $user->password, 
     "user_role" => $user->user_role, 
     "account_status" => 1, 
     ); 
     $this->db->select('*'); 
     $this->db->from('users'); 
     $this->db->where($conditions); 
     $rs= $this->db->get(); 

     if(!empty($rs)){ 
      $result_array = $rs->row_array(); 
      if(password_verify($user->password,$result_array['password'])){ 
      return $result_array; 
     } 
    } 
    return false; 
} 

password_hash和password_verify是否正確？ 而下面是錯誤代碼：

嚴重性：警告

消息：非法串偏移 'ID'

文件名：控制器/ login.php中

行號：38

以及其他字符串session_array

刪除foreach循環，一切都很好

public function index() 
{ 
    if($this->input->post('login') == 1) 
    { 
     $user = new Users_model(); 
     $user->email = $this->input->post('email'); 

     $user->password = $this->input->post('password'); 

     $user->user_role = $this->input->post('user_role'); 
     $results = $this->usermodel->login($user); 

     if(count($results)>0) 
     { 
      if(is_array($results) || is_object($results)) 
      { 
       $session_array = array(
        "id" => $results['id'], 
        "username" => $results['username'], 
        "email" => $results['email'], 
        "password" => $results['password'], 
        "image" => $results['image'], 
        "description" => $results['description'], 
        "account_status" => $results['account_status'], 
        "user_role" => $results['user_role'] 
        ); 
       $this->session->set_userdata($session_array); 
       $url = base_url() . "home?login=success"; 
        redirect($url, "refresh"); 
      } 
     } 
     else 
     { 
      $url = base_url() . "login?login=failed"; 
      redirect($url, "refresh"); 
     } 
    } 
    else 
    { 
     $this->load->view('login-page'); 
    } 
}
