Description:

Translator throws warning when trying to translate a whole translation file containing array keys and using replace keys feature.

Last known to work with v8.61.0

Steps To Reproduce:

trans('validation', ['key' => 'to_replace'], 'en')

outcome:
PHP Warning: strtr() expects parameter 1 to be string, array given in /app/vendor/laravel/framework/src/Illuminate/Translation/Translator.php on line 226

You're trying to call trans on an entire validation file. You should call it like trans('validation.<your-key-here>', ['key' => 'to_replace'], 'en').

It is easy to close since translating an entire file is not mentioned in the documentation but it used to work.

Here is the output using v8.83.7 raising a warning

And this is the output using v8.66.0 , which had no problem replacing even in nested translation keys.

My real world usecase was tranlating an entire file with nested translation keys in one go, which used to work before #39298

I will get around it, but I still consider it a regression since it used to work.
