To enable extensions, verify that they are enabled in your .ini files:
- C:\tools\php\php.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-intl` to temporarily ignore these required extensions.
