How to drive a captcha into a site from another site?

Good day, I would like to know how to change the captcha on another site so that it changes on my site as well?

Let’s say if, for example, there are a lot of pages (anyone will be too lazy to create each one), I want to copy it to my site so that when I go to a page of a certain site, phpchanges the specified “phrases” to mine, and deletes too much?

Answer 1, authority 100%

About the captcha: if the captcha stops sending data to your site, then it cannot be taken from another site. If the site where the data will go, then take it as it is. As for your design and other people’s lines or links – learn to code and parse, since you are too lazy to do something yourself.

Answer 2

Can use iframe for captcha. )) I did something similar on one resource – I did an authorization panel with another site. The registration form and design were mine, and when the user logged in, the data was sent to the partner site and the necessary pages were opened in the iframe.
