Sort Multidimensional Array by Alphanumeric value in Magento 2.4.6

Question

For Example, my Array is something like this :

$testArray = [
    "01-01A" => [
        'name' => "test1",
        'test' => "01-01A"
    ],
    "01-06B" => [
        'name' => "test2",
        'test' => "01-06B"
    ],
    "02-05A" => [
        'name' => "test3",
        'test' => "01-05A"
    ],
    "03-33B" => [
        'name' => "test4",
        'test' => "01-33B"
    ],
    "01-044B" => [
        'name' => "test5",
        'test' => "01-044B"
    ],
    "07-098A" => [
        'name' => "test1",
        'test' => "01-098A"
    ],
    "09-0963B" => [
        'name' => "test2",
        'test' => "01-0963B"
    ],
    "10-0596C" => [
        'name' => "test3",
        'test' => "01-0596C"
    ],
    "99-0586C" => [
        'name' => "test4",
        'test' => "01-0586C"
    ],
    "21-984E" => [
        'name' => "test5",
        'test' => "01-984E"
    ]
];

How can I sort this array using a key or 'test' ??

Output:

01-01A
01-05A
01-098A
01-06B
01-33B
01-044B
01-0963B
01-0586C
01-0596C
01-984E

Answer 1

According to my knowledge,This will not sort because key "test" value is a combination of numeric, string and dash.

If you change key "test" value without dash then natsort() function will sort the array having value(numeric with string).

Answer 2

Solution :

uksort($testArray, function ($key1, $key2) {
    // Extract letters from keys
    $letter1 = substr($key1, -1);
    $letter2 = substr($key2, -1);
    // Compare letters
    $letterComparison = strcmp($letter1, $letter2);
    // If letters are the same, sort by numeric part of keys
    if ($letterComparison === 0) {
        $numericPart1 = (int) substr($key1, 3, -1); // Extract numeric part of key1
        $numericPart2 = (int) substr($key2, 3, -1); // Extract numeric part of key2
        return $numericPart1 - $numericPart2; // Compare numeric parts
    }
    return $letterComparison;
});

Answer 3

Maybe this is the simplest way you can try:

<?php

$testArray = [
    "01-01A" => [
        'name' => "test1",
        'test' => "01-01A"
    ],
    "01-06B" => [
        'name' => "test2",
        'test' => "01-06B"
    ],
    "02-05A" => [
        'name' => "test3",
        'test' => "01-05A"
    ],
    "03-33B" => [
        'name' => "test4",
        'test' => "01-33B"
    ],
    "01-044B" => [
        'name' => "test5",
        'test' => "01-044B"
    ],
    "07-098A" => [
        'name' => "test1",
        'test' => "01-098A"
    ],
    "09-0963B" => [
        'name' => "test2",
        'test' => "01-0963B"
    ],
    "10-0596C" => [
        'name' => "test3",
        'test' => "01-0596C"
    ],
    "99-0586C" => [
        'name' => "test4",
        'test' => "01-0586C"
    ],
    "21-984E" => [
        'name' => "test5",
        'test' => "01-984E"
    ]
];

// get name as an separate array
$name = array_column($testArray, 'name');
// sorting $testArray ascending base on `name`
array_multisort($name, SORT_ASC, $testArray);

print_r($testArray);

and the result will be:

Array
(
    [01-01A] => Array
        (
            [name] => test1
            [test] => 01-01A
        )

    [07-098A] => Array

        )

    [01-06B] => Array
        (
            [name] => test2
            [test] => 01-06B
        )

    [09-0963B] => Array
        (
            [name] => test2
            [test] => 01-0963B
        )

            [test] => 01-05A
        )

    [99-0586C] => Array
        (
            [name] => test4
            [test] => 01-0586C
        )

    [03-33B] => Array
        (
            [name] => test4
            [test] => 01-33B
        )

    [01-044B] => Array
        (
            [name] => test5
            [test] => 01-044B
        )

    [21-984E] => Array
        (
            [name] => test5
            [test] => 01-984E
        )
