怎樣的foreach模型意見fuelphp

Question

我有Model_User

// Get Exams by User 
public static function get_exam_by_user($user_id) { 
    $query = "SELECT e.exam_id, e.exam_code, e.exam_name, e.description, e.creator, e.password, 
       e.max_attempt, e.random_order, e.max_time, e.max_score, e.min_score, e.grading, 
       e.created_at, e.updated_at 
       FROM exam e, user_exam ue 
       WHERE ue.exam_id = e.exam_id 
       AND ue.status = 1 
       AND ue.user_id = :user_id"; 
    $result = DB::query($query)->bind('user_id', $user_id)->execute(); 
    return $result->as_array(); 
} 

與此控制器

public function action_index() { 
    $data = array(); 
    //$data['user_id'] = \Auth\Auth::get('id'); 
    //$data['username'] = \Auth\Auth::get('username'); 
    $user_id = Auth\Auth::get('id'); 
    //$data['exams'] = Model_Exam::find('all'); 
    $data['exams'] = Model_Exam::get_exam_by_user($user_id); 
    $this->template->title = "Exams"; 
    $this->template->content = View::forge('admin/exam/index', $data); 
} 

如何的foreach到的意見？我嘗試printr_r

Array ([0] => Array ([exam_id] => 2 [exam_code] => SD_K1S1_MAT [exam_name] => Ujian Matematika SD Kelas 1 Sem 1 [description] => [creator] => RF [password] => [max_attempt] => 3 [random_order] => 1 [max_time] => 60 [max_score] => 100 [min_score] => 0 [grading] => [created_at] => 2013 [updated_at] => 2013) [1] => Array ([exam_id] => 2 [exam_code] => SD_K1S1_MAT [exam_name] => Ujian Matematika SD Kelas 1 Sem 1 [description] => [creator] => RF [password] => [max_attempt] => 3 [random_order] => 1 [max_time] => 60 [max_score] => 100 [min_score] => 0 [grading] => [created_at] => 2013 [updated_at] => 2013)) 

，如果你可以幫助解決這個問題

Answer 1

I th墨水，你可以做這樣的事情：

<?php foreach ($exams as $exam): 
echo $exam['exam_id']; 
    echo $exam['exam_code']; 
echo $exam['exam_name']; .... and so on.... 

希望是你所需要的。
