问题
I have a script which will add to a databse everytime a page is viewed, I don't want bots triggering the script portion which adds to the database. Basically, I want to only log real users.
Anyway to have bots ignore a section of PHP script?
Thanks!
回答1:
While not foolproof, you can check the USER_AGENT string and only run that code if 'bot' does not exist.
if(stripos($_SERVER['HTTP_USER_AGENT'],'bot') === false){ }
This would stop any bot that actually has bot in the user agent string that also does not pay attention to robots.txt.

you could make a robots.txt file restricting bots from accessing the pages or directories that you don't want them too. Here is a link that will show you how the robots.txt works Robots.txt

Why not do something like this, it will only request that the bots stay away, whether they do or dont is up to their discretion!
User-agent: *
Disallow: /my_page.php
