Invites that are generated can be invalid paths

Created method to generate URL safe codes.

  protected static function generateUrlSafeCode(int $length): string {
    $chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
    $code = '';

    for ($i = 0; $i < $length; $i++) {
      $code .= $chars[random_int(0, strlen($chars) - 1)];
    }

    return $code;
  }

Maybe the solution on #3 works, however just as a curiosity, isn’t possible implementing this with Regex?

NVM, please ignore my question above. Regex is for matching, not creating

So seems good, thanks
