Most of the developers like to show PHP  files as HTML. This can be done via htaccess.  .htaccess files (or “distributed configuration files”) provide a way to make configuration changes on a per-directory basis. In htaccess, we have Rewrites. Htaccess Rewrites are enabled by using the Apache module mod_rewrite, which is one of the most powerful Apache modules and features availale. Htaccess Rewrites through mod_rewrite provide the special ability to Rewrite requests internally as well as Redirect request externally. So, if URL comes like http://www.vijayakumar.org/example.html. This URL will be rewritten as http://www.vijayakumar.org/example.php. To do this, we want to place the below line into htaccess, which was presented in root directory(htaccess will be hidden, try accessing hidden files in your root directory. If not presented?, please create a new htaccess file in root directory).

RewriteRule (.*)\.html $1.php
