====Installing IonCube====

ARDI uses IonCube as its security system, which is a module that needs to be downloaded and added to your PHP installation in order for ARDI to function.

If you've started from a blank slate and used one of our installation scripts to install ARDI, IonCube should have been installed automatically and should hopefully be working well.

However, if you've installed onto a system with a different version of PHP to the one that our installation script was expecting - usually because you've upgraded PHP from a non-standard repository, or your distribution of Linux has very recently had its packages updated - then you might need to manually install IonCube.

ARDI will have made all of the major changes - the issue that will remain is the installation of the IonCube shared library.

===Shared Library Installation Steps===

First, find the suitable version of the IonCube loader, available from [[http://www.ioncube.com/loaders.php]].

When you unzip this file, it will contain several different libraries. You will need to identify which one you need. To do that, ask PHP which version you have installed.

<code>php -v</code>

This will give you something like this...

**PHP 5.6.23-0+deb8u1 (cli)**

Which identifies that you have PHP 5.6 installed, so will therefore need the PHP 5.6 version of the loader. The file name should be //ioncube_loader_lin_5.6.so//

Now find where the library needs to be installed...

<code>php -i | grep extension_dir</code>

This should give the following output...

**extension_dir => /usr/lib/php5/20131226 => /usr/lib/php5/20131226**

Which lets you know //where// to place your file.

Do this with a copy command, renaming the file to simply 'ioncube.so' while doing so.

<code>cp ioncube_loader_lin_5.6.so /usr/lib/php5/20131226/ioncube.so</code>
