Pull Request: https://github.com/php/web-php/pull/1081 Author: takaram
This PR introduces a new class, `LangChooser`, replacing the `language_choose_code()` function. The goal is to make `/releases/8.3/index.php` respect users' language preferences, similar to the manual pages. I initially considered reusing `language_choose_code()`, but its reliance on global variables made that challenging. As a result, I refactored the logic into a new class to simplify reuse in the `/releases` pages. A follow-up PR to update `/releases/8.3/index.php` will be submitted once this PR is merged.
