一般来说都是将eval 改成 var_dump可以看到源代码了。

$arrhttphost = explode('.',$_SERVER['HTTP_HOST']);

$site_url = str_replace('http://','',$options_lic['site_url']);

		if($letutaocode && $lic_username){

		$return_data = aac("system")->license->isCode($lic_username,$letutaocode);



	

		if($return_data!=='10001'
------解决方案--------------------
$return_data!=='10002'){

	

		$arrData = array(

			'site_lication' => $letutaocode,

			'lic_username' => $lic_username,

			);

			foreach ($arrData as $key => $val){

			$db->query("UPDATE ".dbprefix."system_options SET optionvalue='$val' where optionname='$key'");

		}

		

		$arrOptions = $db->fetch_all_assoc("select optionname,optionvalue from ".dbprefix."system_options");

		foreach($arrOptions as $item){

				$arrOption[$item['optionname']] = $item['optionvalue'];

		}

		

		fileWrite('system_options.php','data',$arrOption);

		

		

		qiMsg("Gope.Cn提示恭喜您，授权成功：www.Gope.cn^_^",'进入后台');

				qiMsg("授权码错误，或者用户名不存在,如不清楚请联系www.Gope.cn！");

		}else{

			

			qiMsg("授权码错误，或者用户名不存在,如不清楚请联系www.Gope.cn！");

}



if($le=='re_lic'){

	

	if(_post('submit','intval')){

		

		$countAdmin	= $db->once_fetch_assoc("select count(userid) from ".dbprefix."user where userid='1' and pwd='".md5(_post('adminpwd','trim'))."'");

		if($countAdmin['count(userid)'] == 0) qiMsg("您输入的管理员密码错误！");

		

		foreach($options_lic as $key=>$item){

		if($key=='site_lication'
------解决方案--------------------
$key=='lic_username'){

			

		}else{

			

			$arrOption[$key]= $item;	

			

		}

}

		if(is_array($arrOption)){

			fileWrite('system_options.php','data',$arrOption);

		}

		

		  header("Location:".SITE_URL."index.php?app=lic&ac=lication");

		

		

	}

	

	

}



include template("lication");

------解决方案--------------------
1.把printf函数的字符串用BASE64解码
2.把变量名替换成简单的
3.看eval
