ionCube loader is the PHP extension that decodes encrypted PHP files at runtime. Most commercial hosting companies have ionCube loader installed already. But if this is not your case, here's how to install the loader.

Steps:

• Login via SSH to your server as root

• Download the loader from ionCube:

  wget http://downloads2.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.bz2
  

  Wait until its finished:

• Extract the loader package:

  tar xvjf ioncube_loaders_lin_x86.tar.bz2
  

• Check your PHP version:

  php -v
  

  You'll see something like this:
  

  [root@]# php -v
  PHP 5.1.6 (cli) (built: May 24 2008 14:07:53)
  Copyright (c) 1997-2006 The PHP Group
  Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
  

  So, my PHP version is: 5.1
  The ionCube module I'll be used is: ioncube_loader_lin_5.1.so

• Copy the ionCube module to PHP modules directory.

  cp ioncube/ioncube_loader_lin_5.1.so /usr/lib/php/modules/
  

• Add the module into PHP configuration file

  nano /etc/php.d/ioncube.ini
  

• Add the following line:

  zend_extension = /usr/lib/php/modules/ioncube_loader_lin_5.1.so
  

• Save and exit from nano.

  Ctrl + O
  Ctrl + X
  

• Restart Apache

  service restart httpd
  

  
  OR
  

  /etc/init.d/httpd
  

• Verify the module:

  php -v
  

  
  You'll see something like these:
  

  [root@]# php -v
  PHP 5.1.6 (cli) (built: May 24 2008 14:07:53)
  Copyright (c) 1997-2006 The PHP Group
  Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
      with the ionCube PHP Loader v3.3.11, Copyright (c) 2002-2010, by ionCube Ltd.
  

• Done.

Good luck!
