| CAPTCHA validation using PHP and Ajax | Hits: 91 |
Description: CAPTCHA has become a popular means of securing forms against automated submission, by requiring users to enter a string displayed in an automatically generated image. This implementation uses Ajax to conveniently combine CAPTCHA into normal pre-submission form verification. You'll need PHP to be installed with the GD image library (most PHP implementations will have this as standard).
