预定义常量

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.

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::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.
