I want to hide extensions on my webpage using the .htaccess file.

I have managed to do it by using this code;

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

So when I visit mysite.com/index it shows my index.php. That's fine but I want to block visitors from visiting mysite.com/index.php so it should be redirected to mysite.com/index

I think I have found a way to do that. However, I will be using querystrings on my webpage. There will be some pages which I will need to carry the variables via GET method.

Normally a link with an id variable is like this; index.php?id=xx

However, if I redirect /index.php to /index my variables will be gone. So I want the urls to seem like this when carrying a variable mysite.com/index?id=xx

The extension will be PHP always. But I want this system work in all pages with all variables. I am not sure how many pages and variables there will be so do I have to write a rule in htacces for each of them or can I define a general rule? So it will be like this

Examples:
index.php?id=xx will be index?id=xx
index.php?page=xx will be index?page=xx
users.php?uid=xx will be users?uid=xx
news.php?nid=xx will be news?nid=xx

This could probably be achieved using .htaccess file but I don't know, how can I do that.

P.S. Although I am pretty good at PHP, I don't know anything about creating a rule for htaccess file I just use the codes I find on the internet.

Use that in root .htaccess:

RewriteEngine On
RewriteCond %{THE_REQUEST} \s/+(.+)\.php[\s?] [NC]
RewriteRule ^ /%1 [R=302,L,NE]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^\.]+)$ $1.php [NC,QSA,L]
  • It worked with this. However, now I can't visit directories like this mysite.com/images/ there is a directory called images but when I open mysite.com/images/ it looks for a images.php file and gives 404 error – Nanoripper Dec 22 '14 at 1:46
  • I just add the -d test for that – Croises Dec 22 '14 at 7:33

Based on this question you will need something like this:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^\.]+)$ $1.php [NC,QSA,L,E=LOOP:1]    

RewriteCond %{ENV:REDIRECT_LOOP} !1
RewriteRule ^(.*)\.php$ /$1 [NC,QSA,R=301,L]

!-f and !-d ensure that it doesn't get executed for files and directories that exist

The environment variable LOOP is so that mod_rewrite doesn't try to redirect back to your friendly URLs from the rewritten URLs. It is read as REDIRECT_LOOP because mod_rewrite makes two passes over the rules and prepends REDIRECT_ to all environment variables the second time.

QSA is the "query string append" flag for rewrite rules that preserves your parameters
