Codeigniter 生成静态页面

    使用CI来生成静态页面,其实很简单,就像论坛里面说的那样,读出页面中的数据,再写入html文件中,最后显示这个html文件就行了,好吧,上码。

 

 

[php] 

                

class MY_Loader extends CI_Loader {  

                    

    public function m_view($view, $vars = array(), $return = FALSE){  

        return $this->_m_ci_load(array('_ci_view' => $view, '_ci_vars' => $this->_ci_object_to_array($vars), '_ci_return' => $return));  

    }  

                    

    protected function _m_ci_load($_ci_data){  

          .....  

                      

            $_ci_html_file=($_ci_ext==='')? $_ci_view.".html" : $_ci_view;//这,生成静态页面的文件名   

                            

            foreach ($this->_ci_view_paths as $_ci_view_file => $cascade){  

                if (file_exists($_ci_view_file.$_ci_file)){  

                    $_ci_path = $_ci_view_file.$_ci_file;  

                    $_ci_html_path=$_ci_view_file.$_ci_html_file;//生成静态页面的路径   

                    $file_exists = TRUE;  

                    break;  

                }  

      ......  

            }  

        }  

                

     .......  

        //在这   

      if(config_item("html")===TRUE){//是否开启生成静态页面   

            $_html_file=@fopen($_ci_html_path,'r');//创建.html文件   

            $buffer = ob_get_contents();  

            @ob_end_clean();  

            if(!$_html_file||(@filesize($_ci_html_path)!=strlen($buffer))){ //如果文件不存在或文件已更变   

                $_html_file=@fopen($_ci_html_path,'w');  

                flock($_html_file, LOCK_EX);  

                fwrite($_html_file, $buffer);
