Managing your Applications
By default, it is assumed that you only intend to use CodeIgniter to manage one application, which you will build in your application directory. It is possible, however, to have multiple sets of applications that share a single CodeIgniter installation, or even to rename or relocate your application directory.
Renaming or Relocating the Application Directory
If you would like to rename your application directory or even move
it to a different location on your server, other than your project root, open
your main app/Config/Paths.php and set a full server path in the
$appDirectory variable (at about line 45):
public $appDirectory = '/path/to/your/application';
You will need to modify two additional files in your project root, so that
they can find the
Paths configuration file:
/sparkruns command line apps; the path is specified on or about line 36:
$pathsConfig = 'app/Config/Paths.php'; // ^^^ Change this line if you move your application folder
/public/index.phpis the front controller for your webapp; the config path is specified on or about line 20:
$pathsConfig = FCPATH . '../app/Config/Paths.php'; // ^^^ Change this if you move your application folder
Running Multiple Applications with one CodeIgniter Installation
If you would like to share a common CodeIgniter framework installation, to manage several different applications, simply put all of the directories located inside your application directory into their own (sub)-directory.
For example, let’s say you want to create two applications, named “foo” and “bar”. You could structure your application project directories like this:
/foo /app /public /tests /writable /bar /app /public /tests /writable /codeigniter /system /docs
This would have two apps, “foo” and “bar”, both having standard application directories
public folder, and sharing a common codeigniter framework.
index.php inside each application would refer to its own configuration,
../app/Config/Paths.php, and the
$systemDirectory variable inside each
of those would be set to refer to the shared common “system” folder.
If either of the applications had a command-line component, then you would also
spark inside each application’s project folder, as directed above.
