求大牛帮忙破解phpchart的加密

上次看一个网站介绍phpchart做图表很好看。于是就用了它的免费版phpchart_lite做了一些图表放在网站上。但现在他们似乎改版了。phpchart_lite只支持line render。以前可是支持全部的啊。结果我的网页打不开了。。。他们源码是加密的，求大牛帮我看看吧。千谢万谢。
我以后不会用他们了。只是以前写的那些php程序改版真的麻烦。这是个教训啊。以后用网上的资源要慎重。不要用那些源码加密的。呜呜呜

回复讨论(解决方案)

在网上大概搜索了一下，结果就出来了这么个东西。。。你看看有没有帮助啊。。

<?php   error_reporting(E_ALL);    ini_set('display_errors', 1);      if(!isset($_SERVER['DOCUMENT_ROOT'])){ if(isset($_SERVER['SCRIPT_FILENAME'])){   $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF'])));  }; };  if(!isset($_SERVER['DOCUMENT_ROOT'])){ if(isset($_SERVER['PATH_TRANSLATED'])){   $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr(str_replace('\\\\', '\\', $_SERVER['PATH_TRANSLATED']), 0, 0-strlen($_SERVER['PHP_SELF'])));  }; };      define('ADDITIONAL_JS_FILES', implode(',', array()));    define('ADDITIONAL_CSS_FILES', implode(',', array()));      define('JS_HIGHLIGHT_CSS_STYLE', "zenburn");    require_once(dirname(__FILE__) .'/conf.php');   require_once(dirname(__FILE__) .'/server/cls_util.php');   require_once(dirname(__FILE__) .'/server/cls_axes.php');   require_once(dirname(__FILE__) .'/server/cls_conf.php');   require_once(dirname(__FILE__) .'/server/cls_grid.php');   require_once(dirname(__FILE__) .'/server/cls_legend.php');   require_once(dirname(__FILE__) .'/server/cls_phpchartx.php');   require_once(dirname(__FILE__) .'/server/cls_series.php');   require_once(dirname(__FILE__) .'/server/cls_title.php');   ?>

这不就是个入口文件吗？

<?phperror_reporting(E_ALL);ini_set('display_errors', 1);if(!isset($_SERVER['DOCUMENT_ROOT'])) {  if(isset($_SERVER['SCRIPT_FILENAME'])) {    $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr($_SERVER['SCRIPT_FILENAME'], 0, 0-strlen($_SERVER['PHP_SELF'])));  }}if(!isset($_SERVER['DOCUMENT_ROOT'])) {  if(isset($_SERVER['PATH_TRANSLATED'])) {    $_SERVER['DOCUMENT_ROOT'] = str_replace( '\\', '/', substr(str_replace('\\\\', '\\', $_SERVER['PATH_TRANSLATED']), 0, 0-strlen($_SERVER['PHP_SELF'])));  }}define('ADDITIONAL_JS_FILES', implode(',', array()));define('ADDITIONAL_CSS_FILES', implode(',', array()));define('JS_HIGHLIGHT_CSS_STYLE', "zenburn");require_once(dirname(__FILE__) .'/conf.php');require_once(dirname(__FILE__) .'/server/cls_util.php');require_once(dirname(__FILE__) .'/server/cls_axes.php');require_once(dirname(__FILE__) .'/server/cls_conf.php');require_once(dirname(__FILE__) .'/server/cls_grid.php');require_once(dirname(__FILE__) .'/server/cls_legend.php');require_once(dirname(__FILE__) .'/server/cls_phpchartx.php');require_once(dirname(__FILE__) .'/server/cls_series.php');require_once(dirname(__FILE__) .'/server/cls_title.php');?>

另外需要注意的是：老的 phpchart 是用 js 绘图的，而新版 phpchart 改用 HTML5 绘图
如果你的用户群不都是用支持html5的浏览器的话，请不要盲目升级

大大感谢u010288546和xuzuning版主的热心帮助！
我不是想升级啊，我只是希望以前的代码能继续运行。可是，自从他们升级之后，我的旧版也无法运行了。（是不是他们写的程序中有悄悄与他们服务器联系的后台程序啊？）请问有没有办法还可以用啊？
还有如何破解的？因为我想查看他们是如何禁止我使用他们的代码的。

现在又可以用了，?
