The johnbillion/wp-compat PHPStan extension that now ships with wp-cli-tests checks every WordPress symbol against the WordPress 4.9 baseline that wp-cli-tests configures. It reported exactly one error here, and it is a false positive.

Where Reported Why it is a false positive
src/Fetch_Command.php:147 Parameter $args of apply_filters() is only available since WordPress version 6.0.0 WordPress 6.0 only "formalized the existing and already documented ...$args parameter by adding it to the function signature". Before that, apply_filters() collected additional arguments through func_get_args(), so passing the extra arguments to oembed_result has always worked

Ignored by error identifier and path. No message scoping was needed: WPCompat.parameterNotAvailable.applyfilters.args already names one specific parameter of one specific function, so the entry cannot swallow an unrelated diagnostic.

No source changes: nothing here is an actual compatibility problem.

Verification

Run locally against the same dependency versions CI resolves (johnbillion/wp-compat 2.0.0, php-stubs/wordpress-stubs v6.9.4, wp-cli/wp-cli-tests v5.2.3):

  • composer phpstan[OK] No errors, with no unmatched ignore entries
  • As a control, adding a deliberately dead ignore entry does produce an ignore.unmatched error, confirming the entry above matches a real error rather than sitting there unused

GitHub Actions was failing to allocate runners across the org while this was written, so CI may need a re-run once that clears.

configures. It reported a single error, and it is a false positive: WordPress
6.0 merely formalized the already documented `...$args` parameter of
`apply_filters()` by adding it to the function signature, so passing the extra

Walkthrough

PHPStan configuration now suppresses a documented WordPress compatibility warning for variadic apply_filters() arguments in src/Fetch_Command.php.

Adds documentation and an ignoreErrors entry for the WPCompat.parameterNotAvailable.applyfilters.args diagnostic.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to 062ab

The change only adds a narrowly scoped PHPStan ignore; the remaining issue is an inaccurate rationale naming the filter, which does not affect runtime behavior or ignore matching. No actionable merge-blocking risk remains, though the comment should be corrected.

📢 Thoughts on this report? Let us know!

The comment explaining the ignore referred to `oembed_result`, but the
`apply_filters()` call it covers, and the one wp-compat flags, is
`pre_oembed_result`.
