ionCube PHP Loader on RHEL Server

My work have to use software that requires the ionCube PHP Loader to encode scripts. This instruction is explain "How to install iconCube loader on RHEL4".

1. Goto http://www.ioncube.com/loaders.php and download ionCube loader.
   ioncube_loaders_lin_x86.tar.gz
2. upload to server machine and extract
   tar -zxvf ioncube_loaders_lin_x86.tar.gz
3. Copy the 'ioncube-loader-helper.php' and 'ioncube-encoded-file.php' to a directory where you expect encoded files to be working.
   cp ./ioncube/ioncube-loader-helper.php /your-www-root/
cp ./ioncube/ioncube-encoded-file.php /your-www-root/
4. Access the 'ioncube-loader-helper.php' script from a web server or with a PHP executable. This script can help you to find information about Loader installation.
   http://yoursite.com/ioncube-loader-helper.php
5. Choose the 'run-time loading installation instructions.' option.
   The script will try to locate and install the required Loader, and will produce output as it runs.
   Looking for Loader 'ioncube_loader_lin_5.2.so'

Extensions Dir: /usr/local/php5/lib/php/extensions/current (/usr/local/php5/lib/php/extensions/5.2.8)
Relative Path: /something
6. add the following line before any other zend_extension lines.
   zend_extension = /<path>/ioncube_loader_lin_5.2.sowhere /<path>/ is where you've installed the loader, e.g. /usr/local/php5/lib/php/extensions/5.2.8
   If there are no zend_extension lines already, you can put the line at any point in the file. I'm usingzend_extension = /usr/local/php5/lib/php/extensions/5.2.8/ioncube_loader_lin_5.2.so
7. Copy ioncube_loader_lin_x.x.so to your extension path.
   sudo cp ioncube_loader_lin_5.2.so /usr/local/php5/lib/php/extensions/5.2.8/

Finally, restart your web server software for the changes to take effect.
/etc/init.d/httpd restart
