PHP嵌入开发页面无显示,求大神帮助。

<?php
define('NOROBOT',TRUE);
define('MC_ENTRY',basename(_FILE_));
include_once './include/general.inc.php';
include_once M_ROOT."./include/adminm.fun.php";
include_onceM_ROOT."./include/parse.fun.php";
load_cache('mmnmenus,usualurls,currencys,permissions');
parse_str($_SERVER('QUERY_STRING'),$_da);
$_mp = array();@extract($btags);
extract($_da,EXTR_OVERWRITE);
_aenter($_da,1);
php_refresh(MC_ROOT DIR,'entry.php');
include MC_ROOT DIR.'pcache/entry.php';
_aexit();
?>
这段代码有问题么?
