Backward Incompatible Changes Only

[Erol314]

Hi,
I want to upgrade a project from PHP 8.1 to PHP 8.4
I'd like to fix Backward Incompatible Changes and Deprecations only. as in https://www.php.net/manual/en/appendices.php
But PHP sets for 8.2, 8.3, 8.4 include more rules than I need.
In #8285 author requested something similar.
The answer from the post:

Run php sets one by one, step by step, and just skip that what you don't want :)

Will require some developer time to manually check Each of the rule, according to https://www.php.net/manual/en/appendices.php if I it is really mandatory or not.

Is there a way to add Subsets of rules as

• Minimal set of rules needed to make the code compliant/working on new version( Backward Incompatible Changes)
• Php version Deprecations Excluded .

Hi, thanks for the ping.

You can build those test yourself or use https://github.com/PHPCompatibility/PHPCompatibility

We don't provide such sets by design, as they would create "the least worst" codebase possible :) that's the exact opposite of Rector's mission.

Instead strive to use the latest PHP features, to get the best out of performance and code quality 👍
