Tim was excellent to work with! He truly cared about the project... and made great suggestions for improving my script.

tppCaptcha is an ASCII-art, non-graphical CAPTCHA system that works with PHP versions 4 and 5, does not require any image processing libraries and is very easy to integrate with your existing web site.
It does an excellent job of keeping nasty automated web bots from abusing your web site forms - blocking contact form spam, guestbook spam, and comment spam. It helps block all forms of automated website spam!
Website spam is a serious, growing problem. However, we feel it is a problem you can handle with a carefully considered CAPTCHA solution such as tppCaptcha. I also offer custom installation services.

Example Code
This simple bit of code is enough to protect your forms against website targeted SPAM!
<?php
require_once( 'tppCaptcha.php' );
// setting this to false uses a secure hash
// in a hidden form field making this cookie free!
define( 'tppCaptchaUseSession', true );
tppCaptchaStart();
if ( tppCaptchaVerify() )
{
echo "Passed<br>";
?><a href="example.php">Do Another</a><?php
}
else
{
?><pre style="font-size: .5em;"><?php echo tppCaptchaGenerate( 'big' ); ?></pre>
<form method="GET">
<?php echo tppCaptchaFormField(); ?>
<INPUT TYPE="submit" value="Test Captcha">
</form><?php
}
?>
