Question

我想按照字母顺序升序显示学生列表。假设，学生姓名首先获得A级成绩，然后获得B级。我已尝试但未按字母顺序显示。

感谢您的帮助。

My code
controller:

function showResult(){

         $data['count']=$this->data_Model->getStudent('result');


        $this->load->view('section',$data); 

      } 
Model:
    public function getStudent($table) {


      $query = $this->db->query("SELECT * FROM $table order by grade asc");

          return $query->result_array();

    }

View

section.php
            <?php 
               foreach($count as $student):

                  echo $student['name']; 
                  echo $student['grade'];
              endforeach; ?>

只需按优先级列出“订购依据”字段。升序是默认值，因此您无需指定。

$query = $this->db->query("SELECT * FROM $table order by grade, name");

按字母顺序显示数组使用Codeigniter
