Linux doesn't require filenames or folders to be lowercase - it's just that the filesystem is case-sensitive. That means TestController.php and testcontroller.php are treated as different files.
Yes, this can cause problems, especially when class names, file names, and URI segments don't match exactly in case. That's why we recommend sticking with the default CodeIgniter 4 routing settings for consistency and reliability.
When using $translateUriToCamelCase = true:
A URL like "test-controller" maps to the class "TestController"
When it's set to false:
"testcontroller" maps to "Testcontroller"
And if you also enable $translateURIDashes = true:
"test-controller" becomes "Test_controller"
We prefer using the default settings ($translateUriToCamelCase = true and $translateURIDashes = false) because they’re the most intuitive and align with CodeIgniter 4 coding style and autoloading conventions.
