PHP array_multisort - Sort multiple or multidimensional arrays

In this tutorial learn how to sort multiple or multidimensional arrays, array_multisort() can be used to sort many ways arrays at once, or a multi-dimensional array by one or more dimensions.



Syntax

array_multisort ( array &$array1 [, mixed $array1_sort_order = SORT_DESC [, mixed $array1_sort_flags = SORT_REGULAR [, mixed $... ]]] ) : bool

array_multisort() requires an array of columns, so we use the below code to perform the sorting.


one line code using a array columns using id: array_multisort (array_column($array, 'id'), SORT_ASC, $array);

<?php



$array = Array

(

    0 => Array

        (

            'name' => 'Nakiya',

            'country' => 'USA',

            'id' => 3,

        ),



    1 => Array

        (

           'name' => 'Taylor',

            'country' => 'UK',

            'id' => 2,



        ),



    2 => Array

        (

            'name' => 'Jack',

            'country' => 'France',

            'id' => 1,



        )

);



array_multisort (array_column($array, 'id'), SORT_ASC, $array);


print_r($array);

Above tutorial output (live demo)

Array

(

    [0] => Array

        (

            [name] => Jack

            [country] => France

            [id] => 1

        )



    [1] => Array

        (

            [name] => Taylor

            [country] => UK

            [id] => 2

        )



    [2] => Array

        (

            [name] => Nakiya

            [country] => USA

            [id] => 3

        )
)

Example 2 :  Sorting case Insensitive values

 <?php
$array = array('nakiya', 'Jack', 'Taylor', 'huge');
$array_lowercase = array_map('strtolower', $array);

array_multisort($array_lowercase, SORT_ASC, SORT_STRING, $array);

print_r($array);
?>

Above tutorial output : (live demo)

 Array
(
    [0] => huge
    [1] => Jack
    [2] => nakiya
    [3] => Taylor
)
