Continuation of the the work to fix function argument type issues as reported by PHPStan. These issues are argument types passed to a WP Core and PHP's built-in functions.

The last report was created 3 years ago A new report should be generated as a starting point what issues remain to be fixed in 6.3.

Goals are to:

  • retain the current behavior (i.e. to avoid breaking changes).
  • retain the triggering of notice/warning/error, which are clues and indicators (i.e. rather than silently letting the problem propagate downstream).
  • gain PHP 8 compatibility.
  • ensure code coverage to validate changes.

This ticket is part of the effort to achieve PHP 8+ compatibility.

  • Keywords needs-patch removed

This ticket is not tracking PHP 8+ incompatibilities, thus the php-compatibility focus is not added. Rather, this ticket is an effort of analyzing PHPScan "function argument type issues" and when needed, add defensive code improvements.
