错误现象

Fatal error: This encoded file is corrupted. Please refer to http://www.zend.com/support/support_faq.php?id=loader_file_corrupt for further help in /home/public_html/xspace/index.php on line 0

zend opt 版本

This program makes use of the Zend Scripting Language Engine:
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies with Zend Extension Manager v1.0.10, Copyright (c) 2003-2006, by Zend Technologies with Zend Optimizer v3.0.2, Copyright (c) 1998-2006, by Zend Technologies


是在不明白为什么，请大家帮助，谢谢

输出 phpinfo() 看看 Zend Optmizer 是否生效

生效了，上面zend opt 版本就是phpinfo的信息

请用二进制比特方式上传PHP文件，不要用ASCII码上传
X-Space 是经过Zend Guard编码的，编码后的文件是二进制文件，必须用二进制方式上传才有效
