How to disallow/ban Google bot to view certain webpage

How to disallow Google bot to view a webpage?

Here is one idea:

<?
if(strpos($_SERVER['HTTP_USER_AGENT'],'google') !== false ) { header('HTTP/1.0 404 Not Found'); exit(); }
if(strpos(gethostbyaddr(getenv("REMOTE_ADDR")),'google') !== false ) { header('HTTP/1.0 404 Not Found'); exit(); }
?>

If user agent contains "google", then header 404 (not found) is sent and script is stopped.
If IP address host contains "google", then same thing happens.

an other way is to add <meta name="googlebot" content="noindex" /> as suggested here developers.google.com/search/reference/robots_meta_tag

I totally agree with this option but if you want to do that with the help of on-page coding then you can add a tag like <meta name="googlebot" content="noindex" /> That will block the request of crawling this page.

Here are a few examples

Robots.txt file URL: www.example.com/robots.txt
Blocking all web crawlers from all content
User-agent: * Disallow: /

Blocking a specific web crawler from a specific folder
User-agent: Googlebot Disallow: /example-subfolder/

You can disallow Googlebot in robots.txt file. And you can also use this file and mention any other bots.
