Bug report

PHPStan on PHP 8 is ignoring the fact that the get_include_path() function can only return a string in a comparison statement. It works as expected on lower versions

Code snippet that reproduces the problem

Expected output

PHPStan should complain on PHP8 like it does with prior versions
