Note
On Windows, a file is considered executable, if it is a properly executable file as reported by the Win API GetBinaryType(); for BC reasons, files with a .bat or .cmd extension are also considered executable. Prior to PHP 7.4.0, any non-empty file with a .exe or .com extension was considered executable. Note that PATHEXT is irrelevant for is_executable().
