Ban a bot from loading the output

[Imaster]

Hello,

I have a php script which provides results based on a query. I want to write a code in that php script such that whenever googlebot or any other bot accesses that page, it does not load the output, but rather it provides them with a custom message that I provide.

Any suggestions.

Are you talking about cloaking [searchengineworld.com]?
