A PHP library for generating CAPTCHA images to protect web forms from bots and spam. It builds distorted text images, exposes the phrase for session validation, and can test user input against it.
Use cases
- add captcha to a php contact form
- prevent bot spam on registration forms
- generate captcha images in php
- validate human users before form submission
- protect login forms from automated attacks
When to choose
- you need a self-hosted, dependency-light captcha in a PHP application
- you want full control over captcha appearance and validation without third-party services
When to avoid
- you need accessibility-friendly or invisible bot protection like reCAPTCHA or hCaptcha
- your stack is not PHP
