How to put a captcha in front of the site?

Question

PHP

Actually, the question is how to put a captcha that will appear "in front" of the site when you first visit the site for some countries (for example, China, the Netherlands, etc.)? nginx+php-fpm. Thanks :)

I don't know why you might need this... I don't think this is the best solution. Maybe you should install CloudFlare and make a "hard" filter for these countries?
