PHP Form Captcha

PHP Form Captcha is a powerful script that can protect your form, comment area, guestbook or shopping cart from automatic submissions, the tool generates an image with distorted text which your visitor is required to type into a text box, The idea is to prevent spammers from using web bots to automatically post form data in order to create email accounts (for sending spam) or to submit feedback comments or guestbook entries containing spam messages. The text in the image is usually distorted to prevent the use of OCR (optical character reader) software to defeat the process. Using PHP Form captcha you will be sure that the data entered in your form came from your visitor's fingers not from any computer software.
