PHP Класс Prado\Web\UI\WebControls\TCaptchaValidator

Notice: while this class is easy to use and implement, it does not provide full security. In fact, it's easy to bypass the checks reusing old, already-validated tokens (reply attack). A better alternative is provided by {@link TReCaptchaValidator}. TCaptchaValidator validates user input against a CAPTCHA represented by a {@link TCaptcha} control. The input control fails validation if its value is not the same as the token displayed in CAPTCHA. Note, if the user does not enter any thing, it is still considered as failing the validation. To use TCaptchaValidator, specify the {@link setControlToValidate ControlToValidate} to be the ID path of the input control (usually a {@link TTextBox} control}. Also specify the {@link setCaptchaControl CaptchaControl} to be the ID path of the CAPTCHA control that the user input should be compared with.
