FilesystemIterator::CURRENT_AS_PATHNAME: Makes FilesystemIterator::current() return the pathname.
FilesystemIterator::CURRENT_AS_FILEINFO: Makes FilesystemIterator::current() return an SplFileInfo instance.
FilesystemIterator::CURRENT_AS_SELF: Makes FilesystemIterator::current() return $this (the FilesystemIterator).
FilesystemIterator::CURRENT_MODE_MASK: Masks FilesystemIterator::current()
FilesystemIterator::KEY_AS_PATHNAME: Makes FilesystemIterator::key() return the pathname.
FilesystemIterator::KEY_AS_FILENAME: Makes FilesystemIterator::key() return the filename.
FilesystemIterator::FOLLOW_SYMLINKS: Makes RecursiveDirectoryIterator::hasChildren() follow symlinks.
FilesystemIterator::KEY_MODE_MASK: Masks FilesystemIterator::key()
FilesystemIterator::NEW_CURRENT_AND_KEY: Same as FilesystemIterator::KEY_AS_FILENAME | FilesystemIterator::CURRENT_AS_FILEINFO.
FilesystemIterator::OTHER_MODE_MASK: Mask used for FilesystemIterator::getFlags() and FilesystemIterator::setFlags().
FilesystemIterator::SKIP_DOTS: Skips dot files (. and ..).
FilesystemIterator::UNIX_PATHS: Makes paths use Unix-style forward slash irrespective of system default. Note that the path that is passed to the constructor is not modified.

版本	说明
