Check Spam

Check Spam is a PHP 5 Class package that can be used to generate and validate CAPTCHA validation images. It can create an image in the PNG format displaying a random text. The text is stored in a session variable for later verification. The class can also generate HTML to display the verification image and the inputs of a form in which the user must type the text in the image. The class can verify whether the submitted form input text matches the text in the image. All actions are recorded in a log stored as a class variable.
