PHP CAPTCHA script

[chris89]

Has anyone stumbled on a PHP CAPTCHA script, I'm getting a bit fed up with spam from bots. I was going to have a go at one but I'd rather not re-invent the wheel.

Thanks

Yep. This one is the best, since it doesn't involve typing, and works even if your visitors are dyslexic or have difficulties reading ordinary captchas.

Yep, it's Micrsoft, but it actually works, and it's really good, even great!

I find this is very good and use it on some of the sites i have made. it is very secure and has text and audio options.
