Describe the feature

Per the docs:

php-version (optional)

• ...
• If not specified, it looks for the following in order:
  • The php-version-file input if it exists
  • A composer.lock file and the platform-overrides.php value
  • A composer.json file and the config.platform.php value

However, if composer.json file is in a different sub directory, it could not be located correctly.

So it would be better to support specifying a different path of composer.json file.

Please check the latest release

• I have checked releases, and the feature is missing in the latest patch version of v2.

Underlying issue

Currently the filepath is hard-coded. It would be better to make it customizable:
