Как трансформировать массив?

Question

[Extramezz]

Дано:

array(
  1 => array(
     "name" => "n1",
     "desc" => "desc1"
  ),
  2 => array(
     "name" => "n2",
     "desc" => "desc2"
  )
)

Как оптимальнее получить?

array(
  "name" => array("n1", "n2"),
  "desc"  => array("desc1", "desc2")
)

?

$arr = array(
  1 => array(
     "name" => "n1",
     "desc" => "desc1"
  ),
  2 => array(
     "name" => "n2",
     "desc" => "desc2"
  ),
  3 => array(
     "name" => "n3",
     "desc" => "desc3"
  )
);
$result = array(
    'name' => array_column($arr, 'name'),
    'desc' => array_column($arr, 'desc')
);

var_dump($result);

array (size=2)
  'name' => 
    array (size=3)
      0 => string 'n1' (length=2)
      1 => string 'n2' (length=2)
      2 => string 'n3' (length=2)
  'desc' => 
    array (size=3)
      0 => string 'desc1' (length=5)
      1 => string 'desc2' (length=5)
      2 => string 'desc3' (length=5)

Полагаю, Вы ищете функцию array_column()
