Codeigniter-Pagination：为什么我的数据表显示超过5个条目？

Question

    public function search($offset = 0)
{

    $this->load->library('pagination');

    $per_page = 5;
    $count = $this->db->count_all_results('ghost_projects');
    $config['base_url'] = base_url().'project/search';
    $config['total_rows'] = $count;
    $config['per_page'] = $per_page;
    $config['first_url'] = '1';
    $config['cur_page'] = '1';
    $config['num_links'] = 5;
    $config['cur_tag_open'] = '';
    $config['cur_tag_close'] = '';
    $this->pagination->initialize($config);
    $this->data['projects'] = $this->addproject_m->ongoingprojects($per_page, $offset);     
    $this->data['subview'] = 'project/search';
    $this->load->view('_layout_main_1', $this->data);

这是我控制器中的代码，我已经指定了每页所需的条目，但它显示了10个条目，有人可以告诉我我的代码有什么问题吗？

我在视图中添加了创建链接功能，感谢任何帮助，谢谢：）
