How to handle working folder when Laravel in WSL2 docker environment point to variable folder instead of original project folder? – Phpmyadmin

When I was working on my website using wsl2’s environment (using ./vendor/bin/sail up), some helper such as public_path() and storage_path() are not pointed to the original project folder, below are the output when dump them with dump().

Route::get('/', function () {
    dump(public_path());
    dump(storage_path());
});

^ "/var/www/html/public"
^ "/var/www/html/storage"

This makes me have some problems when dealing with the file uploading function.

Some solutions I tried:

1. Recreate a brand new laravel project and test it out with the public_path() and storage_path().

2. Try it in other device.

Kinda weird when come to the storage link

$ php artisan storage:link

The [/home/ahming/example-app/public/storage] link has been connected to [/home/ahming/example-app/storage/app/public].
The links have been created.

Also it works on the tinker

$ php artisan tinker
Psy Shell v0.11.5 (PHP 8.1.7 - cli) by Justin Hileman
>>> public_path()
=> "/home/ahming/example-app/public"

Edit:

Just find out that using php artisan serve do not have the problem on returning wrong directory, so the problem might be focus on the docker.

When using the sail on running the tinker command, it also returned the same result:

$ ./vendor/bin/sail artisan tinker

>>> public_path()
=> "/var/www/html/public"
