concatenar - php array functions

php | Array merge

Question

Tengo una matriz:

Array
(
[0] => Array
(
[qty] => 2
[id] => 1
[name] => Name 1
[sku] => Model 1
[options] => Color: <em>Black (+10$)</em>. Memory: <em>32GB (+99$)</em>.
[price] => 209.00
)
[1] => Array
(
[qty] => 1
[id] => 1
[name] => Name 1
[sku] => Model 1
[options] => Color: <em>Black (+10$)</em>. Memory: <em>16GB</em>.
[price] => 110.00
)
[2] => Array
(
[qty] => 1
[id] => 3
[name] => Name 2
[sku] => Model 2
[options] =>
[price] => 100.00
)
)

El primer paso es encontrar la misma identificación. Y si existe la misma identificación, convierta una matriz. ¿Es posible obtener una matriz de salida (si id es la misma, eliminar una y agregar cantidad a la otra)?

 Array
(
[0] => Array
(
[qty] => 3 // 2+1
[id] => 1
[name] => Name 1
[sku] => Model 1
[options] => Color: <em>Black (+10$)</em>. Memory: <em>32GB (+99$)</em>.
[price] => 209.00
)
[1] => Array
(
[qty] => 1
[id] => 3
[name] => Name 2
[sku] => Model 2
[options] =>
[price] => 100.00
)
)

¡Gracias!

$result = array();
foreach ($input as $subarray) {
$id = $subarray[''id''];
if (isset($result[$id])) { // Same ID
$result[$id][''qty''] += $subarray[''qty'']; // Add quantities
} else {
$result[$id] = $subarray; // New ID, put in results
}
}
$result = array_values($result); // Convert from associative array to indexed
