Menu hash structure

The menu structure is defined by a multidimensional hash. This makes it quite easy to generate and traverse:

Example 25-1. Menu multidimensional hash array( 1 => array( 'title' => 'Menu item 1', 'url' => '/item1.php', 'sub' => array( 11 => array('title' => 'Menu item 1.1', 'url' => '/item1.1.php'), 12 => array( 'title' => 'Menu item 1.2', 'url' => '/item1.2.php', 'sub' => array( 121 => array('title' => 'Menu item 1.2.1', 'url' => '/item1.2.1.php'), 122 => array('title' => 'Menu item 1.2.2', 'url' => '/item1.2.2.php') ) ) ) ), 2 => array( 'title' => 'Menu item 2', 'url' => '/item2.php', 'sub' => array( 21 => array('title' => 'Menu item 2.1', 'url' => '/item2.1.php'), 22 => array('title' => 'Menu item 2.2', 'url' => '/item2.2.php') ) ) );

Each entry has 'url' and 'title' elements and may also have 'sub' element containing the children of this entry. Note that keys in the entry arrays serve as node identificators and should be unique.

Supported output modes

HTML_Menu supports five output modes: 'tree' (default), 'rows', 'urhere', 'prevnext' and 'sitemap'. Lets use the array defined above as menu structure assuming that element 'Menu item 1.2' is currently active and try each menu type.
