How to Remove .html, .php, .html extensions using .htaccess

An .htaccess file is a simple ASCII file that you create with a text editor like Notepad or TextMate. It provides a way to make configuration changes on a per-directory basis.

Please note that .htaccess is the file’s extension. It isn’t file.htaccess, it is simply .htaccess.

.htaccess files affect the directory in which they are placed and all sub-directories. For example if there is one .htaccess file located in your root directory of yoursite.com, it would affect yoursite.com/content/, yoursite.com/content/images/, etc.

It is important to remember that this can be prevented — for example if you don’t want certain .htaccess commands to affect a specific directory — by placing a new .htaccess file within the directory you don’t want affected with the changes, and removing the specific command(s) from the new .htaccess file that you do not want affecting this directory.

Features

With an .htaccess file you can:

• Redirect the user to different page
• Password protect a specific directory
• Block users by IP
• Preventing hot linking of your images
• Rewrite URIs
• Specify your own Error Documents

In this tutorial we’ll be focusing only on rewriting URIs.

Removing Extensions

To remove the .php extension from a PHP file for example yoursite.com/wallpaper.php to yoursite.com/wallpaper you have to add the following code inside the .htaccess file:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

If you want to remove the .html extension from a html file for example yoursite.com/wallpaper.html to yoursite.com/wallpaper you simply have to alter the last line from the code above to match the filename:

RewriteRule ^([^\.]+)$ $1.html [NC,L]

That’s it! You can now link pages inside the HTML document without needing to add the extension of the page. For example:

<a href="http://whatever.com/wallpaper" title="wallpaper">wallpaper</a>

Adding a trailing slash at the end

I received many requests asking how to add a trailing slash at the end. Ignore the first snippet and insert the following code. The first four lines deal with the removal of the extension and the following, with the addition of the trailing slash and redirecting. Link to the HTML or PHP file as shown above. Don’t forget to change the code if you want it applied to an HTML file.

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/$ $1.php
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]

Some people asked how you can remove the extension from both HTML and PHP files. I haven’t got a coding solution for that. But, you could just change the extension of your HTML file from .html or .htm to .php and add the code for removing the .php extension.
