Lists folders in a format suitable for tree display. An array containing the folders is returned with appropriate information to relate the various folders in a tree structure.

Syntax

void listFolderTree ( $path, $filter, $maxLevel, $level, $parent )

$path string is a string containing the path of the folder to list.
$filter string is a string containing a filter for folder names. The filter is applied as a regular expression, so this syntax should be followed. This parameter is optional and if omitted defaults to an empty string.
$maxLevel integer is an integer containing the value of the maximum number of levels to traverse. This parameter is optional and if omitted defaults to 3.
$level integer is an integer containing the level of the tree to start at. This parameter should usually not be specified. listFolderTree is a recursive function and this parameter is used to pass the level along to child folders. This parameter is optional and if omitted defaults to 0.
$parent integer is an integer containing the parent of the folder to be listed. This parameter should not usually be specified as it is used by the function itself as a means of passing data during recursion. This parameter is optional and if omitted defaults to 0.

Examples

Example

jimport( 'joomla.filesystem.folder' );
