下载一个网站在apache下运行出现了ioncube_loader_win_5.2.dll的错误，说明此网站或者里面文件被加密了。需要安装ioncube Loader组件。
下载地址：http://www.ioncube.com/loaders.php
下载那个Windows (x86) Installer (1.78 MB)的就可以。下载后点击安装。
在php.ini中加上一句：zend_extension_ts =c:\Program Files\ioncube\ioncube_loader_win_5.2.dll 路径要写对
最后打开网站 http://你的网站/ioncube/ioncube-loader-helper.php 如果看到以下信息“An ionCube Loader file is required by PHP to read files encoded with the ionCube Encoder. This page will determine how you can install Loaders on this particular server. An ionCube encoded file has been loaded successfully.Encoded files should now function correctly. If you have a problem with your PHP application, please contact the application provider.”就说明组件安装成功了
