Generating a random color code with PHP

Published on 2024-12-15 • Modified on 2024-12-15

This snippet shows how to generate a random color code with PHP. In the previous snippet, we saw how to generate a random color code with Symfony. We can also directly use PHP. I like the Symfony version because it is readable and elegant, but the PHP version is more straightforward.

<?php

declare(strict_types=1);

namespace App\Controller\Snippet;

use Symfony\Component\HttpFoundation\Request;

/**
 * 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 Snippet333Trait
{
    public function snippet333(Request $request): void
    {
        $colorCode = \sprintf('#%06X', mt_rand(0, 0xFFFFFF)); // FFFFFF = 16 777 215

        echo \sprintf('Color code: %s', $colorCode);

        // That's it! 😁
    }
}
