CI 3的方法不适用于PHP 5.6版本，但适用于PHP 7

我正在使用Codeigniter 3.0.6。我正在开发我的本地服务器，我的PHP版本已经是php7。它运作良好。但后来我上传到使用PHP 5.6的服务器上。然后我得到这个错误。CI 3的方法不适用于PHP 5.6版本，但适用于PHP 7

Parse error: syntax error, unexpected 'list' (T_LIST), expecting identifier (T_STRING) in /var/www/simimi/application/controllers/Student.php on line 53

这里是我的控制器

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 

class Student extends CI_Controller { 

    public function __construct() 
    { 
     parent::__construct(); 
     $this->load->model('m_student','sdb'); 
     $this->load->model('m_student_profile','sdb_pro'); 
     $this->load->model('m_student_academic','sdb_aca'); 
     $this->load->model('m_student_immigration','sdb_imm'); 
     $this->load->model('m_student_emergency','sdb_eme'); 
     $this->cname = 'student'; 
     $this->menu = 'Student'; 
     $this->fitur = ''; 
     $this->active_user=get_nama_user(); 
     $this->active_username=get_username(); 
     $this->active_privilege=get_hak_akses(); 
     if(!cek_auth()) 
     { 
      flash_err('Authorization needed.'); 
      redirect(base_url('auth')); 
     } 
     if(!cek_fitur('student_list')) 
     { 
      flash_err("You don't have privilege to use `{$this->menu}` feature."); 
      redirect(base_url('dashboard')); 
     } 
    } 

    public function index() 
    { 
     $this->list(); 
    } 

    public function action($func='', $id=0) 
    { 
     if(!empty(trim($func))) 
     { 
      if(!empty($id)) 
       $this->$func($id); 
      else if(empty($id)) 
       $this->$func(); 
     } 
     else 
     { 
      flash_err("You don't have permission."); 
      redirect(base_url($this->cname)); 
     } 
    } 

    public function list() 
    { 
     $data['title']='Student'; 
     $data['subtitle']='List'; 
     $data['active']='student_list'; 
     $this->fitur = 'List'; 
     $data['content']='student_list'; 
     $data['students']=$this->sdb->get_list(); 
     $this->load->view('template/template',$data); 
    } 
}

Aaaaand 它只是发生在我允许是一个方法名列表的心不是。我想知道它为什么运行在php7上。
