How to delete an array by value?

Question

PHP

There is such nesting of arrays:

Array
(
    [0] => Array
        (
            [id] => 1
            [prices] => Array
                (
                    [0] => Array
                        (
                            [id] => 1
                            [myprice] => 50
                        )

                    [1] => Array
                        (
                            [id] => 2
                            [myprice] => 1660
                        )

                    [2] => Array
                        (
                            [id] => 8
                            [myprice] => 15
                        )

                )

        )

    [1] => Array
        (
            [id] => 2
            [prices] => Array
                (
                    [0] => Array
                        (
                            [id] => 3
                            [myprice] => 80
                        )

                )

        )

)

It is necessary to remove all final subarrays [prices][$n] that have [prices][$n][id] != 2 I don't see the point in this code.
Thank you.

Answer 1

well, you do two foreach and delete by condition, post here at least your "attempts", because it's hard to even imagine what could be wrong here.

Answer 2

Wrong variant of reassembly

$newarr = Array();
foreach ($arr as $key1 => $item) {
  foreach($item['prices'] as $key2 => $price) {
    if($price['id'] != '2') {
      $newarr[$key1]['prices'][] = $price;
    }
    
  }
  
}
print_r($newarr);
