zip_file_get_external_attributes() function returns
  the operating system and external attributes for the file at position
  index in the zip archive. The external attributes
  usually contain the operating system-specific file permissions. If
  flags is set to
  ZIP_FL_UNCHANGED, the original unchanged values are
  returned. If opsys or attributes
  are NULL, they are not filled in.
The following operating systems are defined by the zip specification:
