Sorting an array, in a sub array php?

Question

PHP

There was a problem when writing a script, I will be very grateful if anyone can help.
The essence of the problem is this:
There is such an array, I need to select all the cold appetizers and salads in the sub array.
This is a kind of array of categories and you need to select sub-categories.

Dump => array(48) {
  [0] => array(8) {
    ["id"] => string(1) "1"
    ["name"] => string(10) "АКЦИЯ"
    ["discount"] => string(1) "0"
    ["img"] => string(0) ""
    ["made"] => string(1) "5"
    ["dop1"] => string(0) ""
    ["dop2"] => string(0) ""
    ["x"] => string(0) ""
  }
  [1] => array(8) {
    ["id"] => string(1) "4"
    ["name"] => string(10) "ОБЕДЫ"
    ["discount"] => string(1) "0"
    ["img"] => string(0) ""
    ["made"] => string(1) "5"
    ["dop1"] => string(0) ""
    ["dop2"] => string(0) ""
    ["x"] => string(0) ""
  }
  [2] => array(8) {

    ["name"] => string(68) "БЛЮДА ИЗ РЫБЫ СОБСТВЕННОГО ХОЗЯЙСТВА"
    ["discount"] => string(1) "0"

    ["dop1"] => string(0) ""

    ["discount"] => string(1) "0"
    ["img"] => string(0) ""
    ["made"] => string(1) "5"
    ["dop1"] => string(0) ""

  }
  [7] => array(8) {
    ["id"] => string(2) "15"
    ["name"] => string(43) "САЛАТЫ мясные с курицей"
    ["discount"] => string(1) "0"

  }

    ["made"] => string(1) "5"
    ["dop1"] => string(0) ""
    ["dop2"] => string(0) ""
    ["x"] => string(0) ""
  }

the result should be

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

General idea.

$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;
