Install ioncube on ubuntu error

Hello,

I need to install ioncube on ubuntu so I did the following:

http://www.aionsolution.com/blog/linux/install-ioncube-in-ubuntu/

IonCube protects software written using the PHP programming language from being viewed, changed, and run on unlicensed computers.

1. Download ionCube loaders

sudo wget http://downloads.ioncube.com/loader_downloads/ioncube_loaders_lin_x86.tar.gz

2. Extract

sudo tar zxvf ioncube_loaders_lin_x86.tar.gz

3. Move to a permanent location

sudo mv ioncube /usr/local/

4. Add reference to your php.ini file (sudo pico /etc/php5/apache2/php.ini)

zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.2.so

There are a few versions of the loader in the tar archive. Use the one that matches your PHP version.

5. Restart apache

sudo /etc/init.d/apache2 restart

6. check installation using following command:
php -v
you should see following output:

PHP 5.1.6 (cli) (built: Apr 7 2009 08:00:04)
Copyright (c) 1997-2006 The PHP Group
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
with the ionCube PHP Loader v3.1.34, Copyright (c) 2002-2009, by ionCube Ltd.

Everything went ok, except the last command: php -v gave the following message:

php -v

And when I want to install the real program that uses IonCube, the web page is blank.

Can you help me?

Thank you
