做使用codeigntier查詢一個foreach？

Question

我試圖做使用笨我的模型foreach，但它給我一個錯誤並返回結果。

下面的代碼：

public function read(){ 
     $questions; //array 
     $query = $this->db->get('questions'); 
     foreach($query->result() as $row){ 
      $getAnswers = $this->db->get_where('answers', array('question_id'=>$row['question_id]']), 4); 
      $questions= $getAnswers; 

      } 

     return $questions; 
    } 

，這是錯誤：

Fatal error: Cannot use object of type stdClass as array in

Answer 1

訪問row作爲一個對象：

$getAnswers = $this->db->get_where('answers', 
        array('question_id'=>$row->question_id), 4);
