Getting a random bounded integer with PHP

Published on 2023-09-07 • Modified on 2023-09-07

This snippet shows how to get a random bounded integer with PHP. This time, we use the randomizer class introduced in PHP 8.2. If you want a cryptographically secure number, use the random_int function. Note that the parameters are included; the function can return 1 and 10 in the following example.



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 Snippet270Trait
    public function snippet270(): void
        $r = new \Random\Randomizer();
        var_dump($r->getInt(1, 10));

        // That's it! 😁
