Как соединить в массиве одинаковые значение?

Question

[MrFreeman94]

Здравствуйте господа.
Есть массив $mainArr в котором

array (
  0 => 
  array (
    'id_product_attribute' => '60',
    'attribute_name' => 'S',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '9565',
  ),
  1 => 
  array (
    'id_product_attribute' => '59',
    'attribute_name' => 'M',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  2 => 
  array (
    'id_product_attribute' => '57',
    'attribute_name' => 'M',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  3 => 
  array (
    'id_product_attribute' => '56',
    'attribute_name' => 'XL',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  4 => 
  array (
    'id_product_attribute' => '58',
    'attribute_name' => 'XL',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  5 => 
  array (
    'id_product_attribute' => '56',
    'attribute_name' => 'Grey',
    'group_name' => 'Color',
    'public_group_name' => 'Color',
    'group_type' => 'color',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  6 => 
  array (
    'id_product_attribute' => '59',
    'attribute_name' => 'Grey',
    'group_name' => 'Color',
    'public_group_name' => 'Color',
    'group_type' => 'color',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  7 => 
  array (
    'id_product_attribute' => '57',
    'attribute_name' => 'Grey',
    'group_name' => 'Color',
    'public_group_name' => 'Color',
    'group_type' => 'color',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  8 => 
  array (
    'id_product_attribute' => '58',
    'attribute_name' => 'Grey',
    'group_name' => 'Color',
    'public_group_name' => 'Color',
    'group_type' => 'color',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  9 => 
  array (
    'id_product_attribute' => '60',
    'attribute_name' => 'Yellow',
    'group_name' => 'Color',
    'public_group_name' => 'Color',
    'group_type' => 'color',
    'attribute_color' => '#F1C40F',
    'quantity' => '9565',
  ),
  10 => 
  array (
    'id_product_attribute' => '56',
    'attribute_name' => '40x60cm',
    'group_name' => 'Dimension',
    'public_group_name' => 'Dimension',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  11 => 
  array (
    'id_product_attribute' => '57',
    'attribute_name' => '40x60cm',
    'group_name' => 'Dimension',
    'public_group_name' => 'Dimension',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  12 => 
  array (
    'id_product_attribute' => '58',
    'attribute_name' => '60x90cm',
    'group_name' => 'Dimension',
    'public_group_name' => 'Dimension',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
  13 => 
  array (
    'id_product_attribute' => '59',
    'attribute_name' => '60x90cm',
    'group_name' => 'Dimension',
    'public_group_name' => 'Dimension',
    'group_type' => 'radio',
    'attribute_color' => '',
    'quantity' => '5555',
  ),
)

Так вот как мне можно конкатенировать название атрибуту по ключу attribute_name
чтобы вышло типо

array (
  0 => 
  array (
    'id_product_attribute' => '60',
    'attribute_name' => 'S, Yellow', 
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '#F1C40F',
    'quantity' => '9565',
  ),
  1 => 
  array (
    'id_product_attribute' => '59',
    'attribute_name' => 'M, Grey, 60x90cm',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  2 => 
  array (
    'id_product_attribute' => '57',
    'attribute_name' => 'M, Grey, 40x60cm',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  3 => 
  array (
    'id_product_attribute' => '56',
    'attribute_name' => 'XL, Grey, 40x60cm',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),
  4 => 
  array (
    'id_product_attribute' => '58',
    'attribute_name' => 'XL, Grey, 60x90cm',
    'group_name' => 'Size',
    'public_group_name' => 'Size',
    'group_type' => 'radio',
    'attribute_color' => '#AAB2BD',
    'quantity' => '5555',
  ),

Если это вообще реально?

Нет, блин.

Расходимся.

foreach ($arr as $item) {
  $id = $item['id_product_attribute'];
  if (!isset($result[$id])) {
    $result[$id] = $item;
  } else {
    $result[$id]['attribute_name'] .= ', '.$item['attribute_name'];
  }
}
