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 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" : $_ci_view;//这,生成静态页面的文件名
foreach ($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, $buffer);
flock($_html_file, LOCK_UN);
fclose($_html_file);
}
//echo(filesize($_ci_html_path)."-".strlen($buffer));
include($_ci_html_path);
}
......
}
}

* in order to show the elapsed page load time. Unless we can
* intercept the content right before it's sent to the browser and
