Is it possible to order an array alphabetically in Laravel?-CodePudding

I am new to Laravel and I was wondering if I can order the following multidimensional array with countries alphabetically? So I want all the countries inside the continents to be ordered alphabetically.

  "EU" => array:9 
    0 => "NL"
    1 => "BE"
    3 => "FR"
    4 => "DE"
    5 => "ES"
    6 => "IT"
    7 => "GB"
    8 => "TR"
    9 => "DK"
  ]
  "AS" => array:2
]

It seems you need to sort an inner array by values. Here is a one way to do it.

$arr = [
   "EU" => [
        0 => "NL",
        1 => "BE",
        3 => "FR",
        4 => "DE",
        5 => "ES",
        6 => "IT",
        7 => "GB",
        8 => "TR",
        9 => "DK",
  ],
  "AS" => ["AB", "AA"]
];

foreach($arr as $continent => $countries) {
    asort($countries);
    $arr[$continent] = $countries;
}


var_dump($arr);

Laravel has nothing to do with these stuff. You should use PHP functions and here's an example:

$arr = [
    0 => "NL",
    1 => "BE",
    3 => "FR",
    4 => "DE",
    5 => "ES",
    6 => "IT",
    7 => "GB",
    8 => "TR",
    9 => "DK",
];

sort($arr);

print_r($arr);

The result:

Array
(
    [0] => BE
    [1] => DE
    [2] => DK
    [3] => ES
    [4] => FR
    [5] => GB
    [6] => IT
    [7] => NL
    [8] => TR
)
