public function __construct() {
    parent::__construct();
    $this->load->helper('directory');
    $this->load->helper('file');
    $this->load->helper('url');
    //$this->output->cache(1440);

public function retrieve($module) {
    $template = $this->config->item('template');
    $dir = '/home/examples/public_html/application/views/resources/' . $template . '/modules/' . $module . '/';

    if(is_dir($dir)) {
        $map = directory_map($dir, 10);
    }
    else {
        show_404(site_url('/css/' . $module));
    }

    $this->output->set_content_type('text/css');
    $this->_process($map);
    //$this->output->get_output();
    //$this->load->view('resources/'.$template.'/modules/'.$module.'/'.$file);

public function _process($arr) {
    foreach($arr as $key => $val) {
        if(is_array($val)) {
            $this->_process($val);
        }
        else {
            $data = read_file($val);
            $this->output->append_output($data);
        }
    }
}
}

/* End of file css.php */
/* Location: ./application/controllers/css.php */

在我的检索方法中..我调用_process方法并将$ data附加到Output类变量，但是我不确定在递归_process函数完成后如何将输出发送到浏览器。任何人对过程功能完成后如何将输出发送到浏览器有任何想法？

Answer 1

您需要调用这些函数：

$this->output->set_content_type('text/css');
    $this->_process($map);

后

$this->load->view();

即。在控制器方法（函数）的末尾

如何使用CodeIgniter中的Output类发送输出
