Create a captcha maker

Without any config:

$maker = CaptchaMaker::createLocal('en'); // or 'nl'

With some custimization:

$maker = new CaptchaMaker();
$maker->add(new ArithmeticCaptcha(new ArithmeticTranslatorLocal(__DIR__ . "/lang/arithmetic-$lang.php")), 10);
$maker->add(new WordListCaptcha(new WordListTranslatorLocal(__DIR__ . "/lang/wordlist-$lang.php")), 20);

10 and 20 for a 10:20 chance of an ArithmeticCaptcha. You can decide which captcha's to use more. Selection is random, but you decice the relative chance.

Create a random captcha

Of a random type:

$captcha = $maker->make();

Or create the type explicitly, and then the captcha:

$type = $maker->random();
$captcha = $type->make();

Translations

nl and en (US) are included. You can add your own language files and select them easily, by manually adding captcha types with translators.

Or you can get translations from anywhere else, by implementing the correct translators (every captcha type has one), and passing it to the captcha type.
