You can sort array with ascending or descending order using SORT_ASC or SORT_DESC also.   


 EXAMPLE 1 : Sort Multi-dimensional array by value of country in this example.

 <?php

$array = Array
(
    0 => Array
        (
            'name' => 'Nakiya',

print_r($array);

Above tutorial output: (live demo)

 Array
(
    [0] => Array
        (
            [name] => Jack
            [country] => France
            [id] => 1

            [country] => USA
            [id] => 3
        )

)

Example 2 : Sort Multi-dimensional array by value of id in this example.

 <?php

$array = Array
(
    0 => Array
        (
            'name' => 'Nakiya',
            'country' => 'USA',

            'country' => 'France',
            'id' => 1,

        )
);

array_multisort(array_map(function($element) {
      return $element['id'];
  }, $array), SORT_ASC, $array);
  
print_r($array);
