How to install ioncube loader in directadmin

ionCube can be installed by following these two steps:

1/ Extract the correct ionCube loader tarball (go here to find the right one for your system) to the /usr/local directory.

e.g.
curl -O http://downloads2.ioncube.com/loader...in_x86.tar.bz2
tar xjfC ioncube_loaders_lin_x86.tar.bz2 /usr/local

2/ You will need to append a line to your PHP.INI to enabel ionCube. ionCube's install helper will give you the exact line to add:
php /usr/local/ioncube/ioncube-loader-helper.php

The line to be appended will look something like:
zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.2.so

After that's appended, ionCube should work. If it's working, php -v should list ionCube as a loaded extension.
