Codeigniter 產生靜態頁面

      使用CI來產生靜態頁面,其實很簡單,就像論壇裡面說的那樣,讀出頁面中的資料,再寫入html檔案中,最後顯示這個html檔案就行了,好吧,上碼。

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');              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" : $_ci_view;//這,產生靜態頁面的檔案名稱                                      foreach ($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;//產生靜態頁面的路徑                    $file_exists = TRUE;                    break;                }      ......            }        }                   .......        //在這      if(config_item("html")===TRUE){//是否開啟產生靜態頁面            $_html_file=@fopen($_ci_html_path,'r');//建立.html檔案            $buffer = ob_get_contents();            @ob_end_clean();            if(!$_html_file||(@filesize($_ci_html_path)!=strlen($buffer))){ //如果檔案不存在或檔案已更變                $_html_file=@fopen($_ci_html_path,'w');                flock($_html_file, LOCK_EX);                fwrite($_html_file, $buffer);                                  flock($_html_file, LOCK_UN);                fclose($_html_file);            }            //echo(filesize($_ci_html_path)."-".strlen($buffer));            include($_ci_html_path);        }                             ......    }  }

調用

$this->load->m_view('login',$datas);

是否產生HTML檔案

$config["html"]               
=  TRUE;




全部代碼如下

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');       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){        // Set the default data variables        foreach (array('_ci_view', '_ci_vars', '_ci_path', '_ci_return') as $_ci_val){            $$_ci_val = isset($_ci_data[$_ci_val]) ? $_ci_data[$_ci_val] : FALSE;        }               $file_exists = FALSE;        // Set the path to the requested file        if (is_string($_ci_path) && $_ci_path !== ''){            $_ci_x = explode('/', $_ci_path);//使用一個字串分割另一個字串            $_ci_file = end($_ci_x);//將數組的內部指標指向最後一個單元        }else{            $_ci_ext = pathinfo($_ci_view, PATHINFO_EXTENSION);// 返迴文件路徑的資訊            $_ci_file = ($_ci_ext === '') ? $_ci_view.'.php' : $_ci_view;            $_ci_html_file=($_ci_ext==='')? $_ci_view.".html" : $_ci_view;//這,產生靜態頁面的檔案名稱                               foreach ($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;//產生靜態頁面的路徑                    $file_exists = TRUE;                    break;                }                       if ( ! $cascade){                    break;                }            }        }               if ( ! $file_exists && ! file_exists($_ci_path))        {            show_error('Unable to load the requested file: '.$_ci_file);        }               // This allows anything loaded using $this->load (views, files, etc.)        // to become accessible from within the Controller and Model functions.        $_ci_CI =& get_instance();        foreach (get_object_vars($_ci_CI) as $_ci_key => $_ci_var)        {            if ( ! isset($this->$_ci_key))            {                $this->$_ci_key =& $_ci_CI->$_ci_key;            }        }               /*         * Extract and cache variables         *         * You can either set variables using the dedicated $this->load->vars()         * function or via the second parameter of this function.
