How can I use .htaccess to hide .php URL extensions?

Remove php extension

You can use the code in /.htaccess :

RewriteEngine on


RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_FILENAME}.php [NC,L]

With the code above, you will be able to access /file.php as /file

Remove html extension

RewriteEngine on


RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^ %{REQUEST_FILENAME}.html [NC,L]

Note : 'RewriteEngine on' directive should be used once at top per htaccess, so if you want to combine these 2 rules just remove the line from second rule. You can also remove any other extensions of your choice, just replace the .php with them on the code.

Happy htaccessing!

Use this code in your .htaccess under DOCUMENT_ROOT:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=302,L,NE]

## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f [NC]
RewriteRule ^ %{REQUEST_URI}.php [L]

It should be noted that this will also effect all HTTP requests, including POST, which will subsequently effect all requests of this kind to fall under this redirection and may potentially cause such requests to stop working.

To resolve this, you can add an exception into the first RewriteRule to ignore POST requests so the rule is not allowed to them.

# To externally redirect /dir/foo.php to /dir/foo excluding POST requests
RewriteCond %{REQUEST_METHOD} !POST
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=302,L,NE]
