thinkphp混编写法页面生成静态化

ob_start();
$static_file ='./home/Tpl/default/Index/s.html';//静态页面
$path = './IndexAction.class.php';
$php_file = basename($path);//当前动态页面
if (!file_exists($static_file) ||
((filemtime($static_file)+1800) filemtime($php_file) > filemtime($static_file)) //判断源文件已修改
{

//下面这部分就是你自己action里面的逻辑
$user = M('user');
$tupian = M('tupianshangchuan');
$tupian = $tupian->select();
$list = $user->where('email="'.Session::get('email').'"')->select();
$this->assign('tupian',$tupian);
$this->assign('list',$list);
$this->display(s_index);
$c = ob_get_contents();
file_put_contents($static_file, $c);
}else{
$this->display('s');
}
