Web Form Examples, With and Without CAPTCHA

Sample PHP-based forms are provided here, with or without a CAPTCHA. A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) adds another level to the forms and helps prevent bots from automatically filling out and submitting multiple copies of your form. The CAPTCHA used here is accessible because it displays a random string of letters and asked the submitter to enter the first four letters it displays. Many CAPTCHAs display a random image file which is not accessible to those who "read" your page using a screen reader.
