I have created a Captcha library that can probably be used in the same way as CodeIgniter3.

Code:

$ composer require kenjis/ci3-like-captcha

PHP Code:

use Kenjis\CI3Like\Captcha\Captcha;

$vals = [
    'word'      => random_string('numeric', 4),
    'img_path'  => FCPATH . 'captcha/',
    'img_url'   => base_url() . '/captcha/',
];
$cap = Captcha::createCaptcha($vals);

$data = [
    'captcha_id'   => '',
    'captcha_time' => $cap['time'],
    'word'         => $cap['word'],
];
