Wrote a CAPTCHA page in another page that contains HTML references the box that uses the include reference verification code is displayed on the page. Ask how to reference and not let the box of the Captcha show up. Thank you PHP include

You can use the session to determine the verification code data.
However, the verification code is transmitted as a picture and loses its meaning.
You can also use AJAX to detect whether the input text is the same as the verification code.
