My knowledge of php is not good and I need help.

I have this php form but I don't know how to add a CAPTCHA mechanism.

How do I achieve this?

I really like Securimage is seems to work really well and does not require a third-party external service or javascript (unless you enable the new image feature). Also it can be configured to provide audio captcha for accessibility.
