PHPUnit: Compare two arrays but ignore order of values

You want to use the assertEqualsCanonicalizing(array $a, array $b) method.

For example, this test will pass because although the order of the values in $array1 and $array2 are different, they contain the same values:

<?php

declare(strict_types=1);

namespace App\Tests\Unit;

use PHPUnit\Framework\TestCase;

class ArrayComparisonTest extends TestCase
{
    public function testArraysAreEqualIgnoringOrder(): void
    {
        $array1 = [1, 2, 3];
        $array2 = [3, 1, 2];

        $this->assertEqualsCanonicalizing($array1, $array2);
    }
}
