php – How to turn the first array of a multidimensional array into a key?

Question:

how can i turn the first array of a multidimensional array into a key? for example this would be my multidimensional array

array (size=5)
  0 => string 'Nome' (length=4)
  1 => string 'd_r_A' (length=5)
  2 => string 'numero' (length=6)
  3 => string 'numerodv' (length=8)
  4 => string 'codtcart' (length=8)

array (size=5)
  0 => string 'Guilherme' (length=9)
  1 => string '32132' (length=5)
  2 => string '123456' (length=6)
  3 => string '987654321' (length=8)
  4 => string '987654321' (length=8)

array (size=5)
  0 => string 'Paulo' (length=9)
  1 => string '32132' (length=5)
  2 => string '123456' (length=6)
  3 => string '987654321' (length=8)
  4 => string '987654321' (length=8)

I would like an array like this

array (size=5)
  'Nome' => string 'Guilherme' (length=9)
  'd_r_A' => string '32132' (length=5)
  'numero' => string '123456' (length=6)
  'numerodv' => string '987654321' (length=8)
  'codtcart' => string '987654321' (length=8)

array (size=5)
  'Nome' => string 'Paulo' (length=9)
  'd_r_A' => string '32132' (length=5)
  'numero' => string '123456' (length=6)
  'numerodv' => string '987654321' (length=8)
  'codtcart' => string '987654321' (length=8)

Answer:

You can use array_map for this situation:

$array_nomes[] = ['Guilherme', '32132', '123456', '987654321', '987654321'];
$array_nomes[] = ['Paulo', '32132', '123456', '987654321', '987654321'];


$array_final = array_map(function($a) {
                                return [
                                    'Nome' => $a[0],
                                    'd_r_A' => $a[1],
                                    'numero' => $a[2],
                                    'numerodv' => $a[3],
                                    'codtcart' => $a[4]
                                ];
                           }, $array_nomes);

// Retorno:    
var_dump($array_final);

This will return:

array(2) {
  [0]=>
  array(5) {
    ["Nome"]=>
    string(9) "Guilherme"
    ["d_r_A"]=>
    string(5) "32132"
    ["numero"]=>
    string(6) "123456"
    ["numerodv"]=>
    string(9) "987654321"
    ["codtcart"]=>
    string(9) "987654321"
  }
  [1]=>
  array(5) {
    ["Nome"]=>
    string(5) "Paulo"
    ["d_r_A"]=>
    string(5) "32132"
    ["numero"]=>
    string(6) "123456"
    ["numerodv"]=>
    string(9) "987654321"
    ["codtcart"]=>
    string(9) "987654321"
  }
}
