## Detailed Description

Folder object used to create and manage groups of items.

Items are identified and manipulated within folders by a positive integer "ID" value. For folders intended to contain multiple types of item types, item types are arbitrary string values.

Parameters

  mixed | $ItemOrItemId | Item to add.
  mixed | $ItemType | Type of item to add. (OPTIONAL, for mixed-item-type folders)

Definition at line 28 of file Folder.php.

References Id(), IsShared(), NormalizedName(), and OwnerId().

Folder::GetItemCount | ( |  | ) |

This does not included nested items, so if a folder contains another folder that contains items, the inner folder is counted as only one item.

Returns
  int Number of items.

Definition at line 293 of file Folder.php.

Folder::GetItemIds | ( |  | ) |

Retrieve array of IDs of items in folder, in the order that they appear in the folder.

Returns
