How to make search engines not to read .php extension urls

Question

How can I restrict the search engine not to read our .php url because we want our clean urls to appear in search engines.

I am using htaccess file for removing .php from all the urls but the search engine is taking both the urls ie with .php and without .php.

I want to make the search engines read only the urls having NO .php extension.

Create a robots.txt file in your website root and include the following to avoid crawling .php extensions.

User-agent: *
Disallow: /*.php$
