Description
Consider the below MRE, which was OK for phpcs-variable-analysis v2.11.12, but receives a warning in v2.11.14 for the part of the code on the last line (between question mark and colon).
Warning: Variable $cls is undefined. (VariableAnalysis.CodeAnalysis.VariableAnalysis.UndefinedVariable)
Note that PHP (8.0) has no issue with the code and it works as expected. As far as I can tell, it might be connected to PR #296.
class Test
{
public function status(): bool
{
return true;
}
public static function hello(callable $callback): void
{
print('Hello');
}
}
Test::hello(fn(Test $cls) => $cls->status() ? $cls : null);This workaround can fix it for now.
class Test
{
public function status(): bool
{
return true;
}
public static function hello(callable $callback): void
{
print('Hello');
}
}
Test::hello(static function (Test $cls): ?Test {
return $cls->status() ? $cls : null;
});
