Screen:

Given the following function:
function someFunc($first, &$byRef = null)
{
}
someFunc('foo');
The warning is resolved when the default value is removed:
function someFunc($first, &$byRef)
{
}
someFunc('foo');
This in case leads to an PHP fatal error:
PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function someFunc(), 1 passed in file.php on line 7 and exactly 2 expected in file.php:3
I dropped the inspection completely in the upcoming 2.3.9: https://github.com/kalessil/phpinspectionsea/commit/902c756fef4ee606976f2cbafcd3de0bbc97bf4a - causes similar problems in real projects.
Ahh my bad, should have searched the repo a bit better. Anyway thanks for your very fast response :1st_place_medal:
No problems, I'm ok for me =)
