Multiple Applications

@Codinglander

If you have "App\\" and "Config\\" in autoload.psr-4 of composer.json, remove them.

Code:

--- a/composer.json
+++ b/composer.json

-            "Config\\": "app/Config"

And update Composer's autoload configuration.

Code:

$ composer dump-autoload

Check the path is correct.

PHP Code:

echo COMPOSER_PATH; exit; 


By the way, why do you want to use Multiple Applications?
It seems there is no particular merit in that configuration.

Just installing two appstarter is easy and simple, and
it could reduce the upgrade costs.

Good Morning....
Path seems to be correct...

but I don't understand why the other manuals using composer not working (e.g. MGatner's settings ).

I need multiple applications for several projects for some sites for kindergarden, all hosted on one domain and there I need for each one subdomain.
Therefore I want to use only ONE ci-installation with many apps, one for every kindergarden...

@Codinglander I found this error is due to a bug.

If the same namespace is defined in both CodeIgniter and Composer, CodeIgniter’s autoloader will be the first one to get a chance to locate the file.
https://codeigniter4.github.io/CodeIgnit...er-support

The namespace Config is defined in CodeIgniter. So it should be loaded even if Composer has a wrong path.

I sent a PR to fix:

Thanks for reporting!
