如何从Codeigniter中的URL中删除“＆per_page =”

Question

我坚持这个问题。我在我的网址上遇到了这个问题。我在我的网址中收到&per_page=。

我在CI中使用分页，其中我使用了以下代码但无法将其删除。

我的网址：http://localhost/abroad_education/entrance/index/0&per_page=3

预期网址：http://localhost/abroad_education/entrance/index/0/3

调节器

class Entrance extends CI_Controller
{
public function __construct()
{ 
    parent::__construct();  
    $this->load->helper('url');
    $this->load->helper('form');

    $this->load->model('Pagination_model',"pgn");
}

public function index()
{   


    if($this->input->post('title') !="")
    {
        $title = trim($this->input->post('title'));
    }
    else{
        $title = str_replace("%20",' ',($this->uri->segment(3))?$this->uri->segment(3):0);
    } 

    $data['search_title']=$title;       
    print_r($title); 
    $allrecord = $this->pgn->allrecord($title);
    $baseurl =  base_url().$this->router->class.'/'.$this->router->method."/".$title;

    $paging=array();
    $paging['base_url'] =$baseurl;
    $paging['total_rows'] = $allrecord;
    $paging['per_page'] = 3;

    $this->pagination->initialize($paging); 

    $data['limit'] = $paging['per_page'];
    $data['number_page'] = $paging['per_page']; 
    $data['offset'] = ($this->uri->segment(4)) ? $this->uri->segment(4):'0/';

    $data['include'] = 'frontend/entrance/entrance';
    $this->load->view('frontend/container', $data);

    $this->load->library(array('session','pagination'));
