Shuffling an array with PHP and the randomizer class

Published on 2023-09-11 • Modified on 2023-09-11

I continue my series about PHP 8.2 and the randomizer class. This time, we see how to shuffle an array thanks to the shuffleArray() function.

<?php

declare(strict_types=1);

namespace App\Controller\Snippet;

/**
 * I am using a PHP trait to isolate each snippet in a file.
 * This code should be called from a Symfony controller extending AbstractController (as of Symfony 4.2)
 * or Symfony\Bundle\FrameworkBundle\Controller\Controller (Symfony <= 4.1).
 * Services are injected in the main controller constructor.
 */
trait Snippet272Trait
{
    public function snippet272(): void
    {
        $r = new \Random\Randomizer();
        $array = ['a', 'b', 'c', 'd', 'foo', 'bar'];

        var_dump($array);
        echo PHP_EOL;
        var_dump($r->shuffleArray($array));

        // That's it! 😁
    }
}
