Do you know Captcha? Hmm.. I think captcha is used to anti spam. Usually, if you want to submit a form, you must read combination codes and write it on text area. If match, the form will submitted and vice versa. It is used to detect you are machine or not.. hah so funny right? but it’s true :p
Hehe.. no more talking, I’ll show you how to create captcha with PHP.. hah PHP again? yup, for captha I used GD Library for rendering image under PHP, so make sure you have installed this extension. To get captcha with PHP you need to create at least 3 PHP file. This is without database. I use session.
