What is Zend Optimizer and why is it used in ViArt?
Some of ViArt's files have been processed with an application called Zend Encoder. These files will not be executed
without Zend Optimizer being installed and configured correctly on your Web Site's Host Server.
Zend Optimizer can decode and execute 'optimised' files with greatly improved performance when compared to standard PHP files.
We use Zend optimisation primarily to provide you with:
- Improved performance: There is a very complex and sophisticated PHP structure which gives ViArt its power,
speed and flexibility. When ViArt is running, there are a great many operations being carried out to create
what you see in your web browser. We have found that by compiling our files with Zend Encoder we can greatly
improve the speed at which these operations are performed, thus creating a faster page rendering time, and
a more responsive web site.
- Safety: The files that govern Viart's underlying framework i.e. the file which hold certain 'protected information'
and the other files we would not expect customers would need to modify, are processed with Zend Encoder.
Since Viart's whole reason for being is to allow customization, we have not encoded all of Viart's files; only
those files which we feel will protect our intellectual property have been optimized. Any files pertaining to
the look and feel of the interface: Style Sheets, HTML, layout files, shopping cart messages and system function
variables are all open to alteration in any way you wish.
We would estimate that 97% of Viart is 'open' for modification in any way you choose.

Most common questions
My Web Host doesn't have Zend Optimizer, what should I do?
Zend Optimizer is a completely free application: it costs nothing to install and run it on your server.
If you have your own web server and you have "root administrator permissions", you will be able to download
Zend Optimizer from the above link and install it without issue.
In most cases where you are relying on another company to host your site, your hosting company's Technical
Support will carry out this operation for you, if indeed Zend Optimizer is not supported already.
Unfortunately, if your web host refuses to install Zend Optimizer, you won't be able to run ViArt
Shop on their server. In this event we would recommend using ViArt's Web Hosting services, details of which can be found here.
How to enable Zend Optimizer?
