    Constantes pré-définies

    FilesystemIterator::CURRENT_AS_PATHNAME

    FilesystemIterator::current() retourne le nom du chemin.

    FilesystemIterator::CURRENT_AS_FILEINFO

    FilesystemIterator::current() retourne un objet SplFileInfo.

    FilesystemIterator::CURRENT_AS_SELF

    FilesystemIterator::current() retourne $this (le FilesystemIterator).

    FilesystemIterator::CURRENT_MODE_MASK

    Masque FilesystemIterator::current().

    FilesystemIterator::KEY_AS_PATHNAME

    FilesystemIterator::key() retourne le nom de chemin.

    FilesystemIterator::KEY_AS_FILENAME

    FilesystemIterator::key() retourne le nom du fichier.

    Makes RecursiveDirectoryIterator::hasChildren() follow symlinks.

    FilesystemIterator::KEY_MODE_MASK

    Masque FilesystemIterator::key().

    FilesystemIterator::NEW_CURRENT_AND_KEY

    Identique à FilesystemIterator::KEY_AS_FILENAME | FilesystemIterator::CURRENT_AS_FILEINFO.

    FilesystemIterator::SKIP_DOTS

    Ignore les fichiers points (. et ..).

    FilesystemIterator::UNIX_PATHS

    Les chemins utilisent le séparateur de dossier de type Unix, soit le slash, indépendamment du système de fonctionnement. Notez que le chemin qui est passé au constructeur n'est pas modifié.

    You may be wondering, like I did, what is the difference between this class and DirectoryIterator?

    When you iteterate using DirectoryIterator each "value" returned is the same DirectoryIterator object. The internal state is changed so when you call isDir(), getPathname(), etc the correct information is returned. If you were to ask for a key when iterating you will get an integer index value.

    FilesystemIterator (and RecursiveDirectoryIterator) on the other hand returns a new, different SplFileInfo object for each iteration step. The key is the full pathname of the file. This is by default. You can change what is returned for the key or value using the "flags" arguement to the constructor.

    DirectoryIterator returns virtual directories "." and ".." in a loop.
    But FilesystemIterator ignores them.

    It's impossible to return dots (. and ..) by FilesystemIterator.
