README

Captcha library for PHP applications.

Requirements

• PHP ^8.1
• PHP Intl extension
• Symfony HttpFoundation ^6.4
• Symfony Security Core ^6.4

PCOV or Xdebug is required only when generating code coverage.

Installation

composer require wiejakp/captcha:^2.0

Usage

use wiejakp\captcha\CaptchaService;

$captcha = new CaptchaService();
$challenge = $captcha->createPositiveCaptchaChallenge();

echo $challenge->getChallenge();

if ($challenge->isEqual($submittedAnswer)) {
    // The answer is valid.
}

Challenges are stored in the configured Symfony session by default. Pass false to a creation method when the generated challenge should not be stored.

Tests

composer test

With PCOV enabled, generate coverage using:
