У меня есть следующий массив:
Array ( [0] => Array ( [id] => 2 [title] => Root 2 [description] => [site_id] => 1 [parent_id] => 0 [created_at] => [updated_at] => [children] => Array ( [0] => Array ( [id] => 4 [title] => Child 2 [description] => [site_id] => 1 [parent_id] => 2 [created_at] => [updated_at] => [children] => Array ( [0] => Array ( [id] => 6 [title] => Child 4 [description] => [site_id] => 1 [parent_id] => 4 [created_at] => [updated_at] => ) ) ) ) ) [2] => Array ( [id] => 7 [title] => Root 3 [description] => [site_id] => 1 [parent_id] => 0 [created_at] => [updated_at] => ) ) Я хотел бы сгладить его примерно так:
Array ( [0] => Array ( [id] => 2 [title] => Root 2 [description] => [site_id] => 1 [parent_id] => 0 [created_at] => [updated_at] => [depth] => 0 ) [1] => Array ( [id] => 4 [title] => Child 2 [description] => [site_id] => 1 [parent_id] => 2 [created_at] => [updated_at] => [depth] => 1 ) [2] => Array ( [id] => 6 [title] => Child 4 [description] => [site_id] => 1 [parent_id] => 4 [created_at] => [updated_at] => [depth] => 2 ) [3] => Array ( [id] => 7 [title] => Root 3 [description] => [site_id] => 1 [parent_id] => 0 [created_at] => [updated_at] => [depth] => 0 ) )
Обратите внимание на клавишу «глубина» – это должно указывать, насколько глубоко в исходном массиве был элемент
Самоназывающие / рекурсивные функции не являются проблемой
Есть идеи?
