Мне надо реализовать вывод категорий и вложенных подкатегорий.Задача вроде стандартная и я знаю что решается она с помощью рекурсии,вроде бы так и делаю.
Вот моя функция:
public function saveDataAsHtml($data) {
if (is_array($this->data)) {
foreach ($this->data as $value) {
echo $value['text'];
if (!empty($value['children'])) {
$this->saveDataAsHtml($value['children']);
}
}
}
}
массив $data имеет следующую структуру
Array
(
[0] => Array
(
[text] => Компьютеры
[parent_id] => 0
[line] => 1
[expanded] =>
[category_id] => 43
[children] => Array
(
[0] => Array
(
[text] => Планшеты
[parent_id] => 43
[line] => 2
[expanded] =>
[category_id] => 49
[children] => Array
(
)
)
[1] => Array
(
[text] => Ноутбуки
[parent_id] => 43
[line] => 2
[expanded] =>
[category_id] => 50
[children] => Array
(
)
)
)
)
[1] => Array
(
[text] => Автомобили
[parent_id] => 0
[line] => 1
[expanded] =>
[category_id] => 44
[children] => Array
(
[0] => Array
(
[text] => Ауди
[parent_id] => 44
[line] => 2
[expanded] =>
[category_id] => 51
[children] => Array
(
)
)
[1] => Array
(
[text] => Шевроле
[parent_id] => 44
[line] => 2
[expanded] =>
[category_id] => 52
[children] => Array
(
)
)
[2] => Array
(
[text] => БМВ
[parent_id] => 44
[line] => 2
[expanded] =>
[category_id] => 53
[children] => Array
(
)
)
)
)
[2] => Array
(
[text] => Бытовая техника
[parent_id] => 0
[line] => 1
[expanded] =>
[category_id] => 45
[children] => Array

(
[text] => hjh
[parent_id] => 48
[line] => 3
[expanded] =>
[category_id] => 54
[children] => Array
(

)
)
)
)
)
[3] => Array
(
[text] => Строительные материалы
[parent_id] => 0
[line] => 1
[expanded] =>
[category_id] => 46
[children] => Array
(
)
)
)
но выдается ошибка
Fatal error: Maximum function nesting level of '100' reached, aborting! in
Помогите пожалуйста разобраться как сделать правильно.
