Can __( method have lowercase parameter ?

personally I keep all translations in lower case and use css to capitalize, this way someone working on front-end does not need to learn php to have control over the way the text is rendered.

In my opinion in Laravel, there's no built-in feature for directly specifying text transformations like capitalization within the __() function for translations. However, you can achieve this by using custom helper functions.

Custom Helper Function

You can create a custom helper function to handle text transformations. Here's an example:

1. Create a Custom Helper Function:

   In your app/helpers.php file (create it if it doesn’t exist), add the following function:

   if (! function_exists('trans_with_transform')) {
       function trans_with_transform($key, $transform = null, $locale = null) {
           $translation = __($key, [], $locale);
           if ($transform === 'capitalized') {
               return \Str::ucfirst($translation);
           }
           // Add more transformations if needed
           return $translation;
       }
   }
   

Do you know how register a Helper ?

for use after register:

{{ trans_with_transform('quiz.select', 'capitalized') }}

You can add more transform methods for your project.
