# Sharing Kohana
|
|
|
|
Kohana follows a [front controller pattern](http://en.wikipedia.org/wiki/Front_Controller_pattern "Front Controller pattern") (which means that all requests are sent to `index.php`) and as such the [filesystem](files) is very configurable. Inside of `index.php` you can change the `$application`, `$modules`, and `$system` paths.
|
|
|
|
[!!] There is a security check at the top of every Kohana file to prevent it from being accessed without using the front controller. Also, the `.htaccess` file should protect those folders as well. Moving the application, modules, and system directories to a location that cannot be accessed via the web can add another layer of security, but is optional.
|
|
|
|
The `$application` variable lets you set the directory that contains your application files. By default, this is `application`. The `$modules` variable lets you set the directory that contains module files. The `$system` variable lets you set the directory that contains the default Kohana files. You can move these three directories anywhere.
|
|
|
|
For instance, by default the directories are set up like this:
|
|
|
|
www/
|
|
index.php
|
|
application/
|
|
modules/
|
|
system/
|
|
|
|
You could move the directories out of the web root so they look like this:
|
|
|
|
application/
|
|
modules/
|
|
system/
|
|
www/
|
|
index.php
|
|
|
|
Then you would need to change the settings in `index.php` to be:
|
|
|
|
$application = '../application';
|
|
$modules = '../modules';
|
|
$system = '../system';
|
|
|
|
## Sharing system and modules
|
|
|
|
To take this a step further, we could point several Kohana apps to the same system and modules folders. For example (and this is just an example, you could arrange these anyway you want):
|
|
|
|
apps/
|
|
foobar/
|
|
application/
|
|
www/
|
|
bazbar/
|
|
application/
|
|
www/
|
|
kohana/
|
|
3.0.6/
|
|
3.0.7/
|
|
3.0.8/
|
|
modules/
|
|
|
|
And you would need to change the settings in `index.php` to be:
|
|
|
|
$application = '../application';
|
|
$system = '../../../kohana/3.0.6';
|
|
$modules = '../../../kohana/modules';
|
|
|
|
With this method each app can point to a central copy of Kohana, and when you add a new version, allow you to quickly update the apps by editing their respective `index.php` files. |
