Here is the print_r of the $results variable at the bottom of the get_all function:
Array ( [0] => Array ( [id] => 1 [title] => Information Technology [parent] => 0 [menu_index] => 4 [depth] => 0 [children] => Array ( [0] => Array ( [id] => 4 [title] => Web Specialist [parent] => 1 [menu_index] => 2 [depth] => 1 ) [1] => Array ( [id] => 5 [title] => Server Room [parent] => 1 [menu_index] => 1 [depth] => 1 ) ) ) [1] => Array ( [id] => 2 [title] => Human Resources [parent] => 0 [menu_index] => 1 [depth] => 0 [children] => Array ( ) ) [2] => Array ( [id] => 3 [title] => Planning [parent] => 0 [menu_index] => 3 [depth] => 0 [children] => Array ( ) ) )
Hopefully, that helps.
