Сортировка массива, в под массив php?

Question

[Дмитрий Кривошеин]

Возникла проблема при написание скрипта, буду весьма благодарен если кто поможет.
Суть проблемы вот в чём:
Есть вот такой массив, мне нужно выделить в под массив, все холодные закуски и салаты.
Это своего рода массив категорий и нужно выделить под категории.

Dump => array(48) {
  [0] => array(8) {
    ["id"] => string(1) "1"

результат должен получиться

Общая идея.

$allFood = []; // сюда поместите массив со всей жратвой
        $coldFoodArray = ['name'=>'ХОЛОДНЫЕ ЗАКУСКИ' , 'sub'=>[]]; // 'sub'=>[] здесь будут холодные закуски
        $saladsArray = ['name'=>'САЛАТЫ' , 'sub'=>[] ];//  'sub'=>[] здесь будут модификации оливье

        foreach ($allFood as $k => $v) {
            if (strpos($v['name'], 'ХОЛОДНЫЕ ЗАКУСКИ')) {
                $coldFoodArray['sub'][] = $v;
                unset($allFood[$k]);
            }
            if (strpos($v['name'], 'САЛАТЫ')) {
                $saladsArray['sub'][] = $v;
                unset($allFood[$k]);
            }
        }

        $allFood[] = $coldFoodArray;
        $allFood[] = $saladsArray;
