How to remove html and php extensions from URL - php

Hello I'm trying to hide html and php extension from my site URLs and here's my .htaccess file
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/install -d
RewriteCond %{REQUEST_URI} !(install) [NC]
RewriteRule ^(.*) /install/ [L,redirect=302]
RewriteCond %{REQUEST_URI} ^(.+)\!$
RewriteRule ^(.*) stats.php?url=$1 [L]
RewriteCond %{REQUEST_URI} ^(.+)\~s$
RewriteRule ^(.*) stats.php?url=$1 [L]
RewriteCond %{REQUEST_URI} ^(.+)\~q$
RewriteRule ^(.*) generate_qr.php?url=$1 [L]
RewriteCond %{REQUEST_URI} ^(.+)\~p$
RewriteRule ^(.*) preview_url.php?url=$1 [L]
RewriteCond %{REQUEST_URI} !^(.+)\.html$
RewriteCond %{REQUEST_URI} !^(.+)\.htm$
RewriteCond %{REQUEST_URI} !^(.+)\.php$
RewriteCond %{REQUEST_URI} !^(.+)\.js$
RewriteCond %{REQUEST_URI} !^(.+)\.css$
RewriteCond %{REQUEST_URI} !^(.+)\.jpg$
RewriteCond %{REQUEST_URI} !^(.+)\.png$
RewriteCond %{REQUEST_URI} !^(.+)\.gif$
RewriteCond %{REQUEST_URI} !^(.+)\.swf$
RewriteCond %{REQUEST_URI} !^(.+)\.xml$
RewriteCond %{REQUEST_URI} !^(.+)\.ico$
RewriteCond %{REQUEST_URI} !^(.+)\.txt$
RewriteCond %{REQUEST_URI} !^index\.html$
RewriteCond %{REQUEST_URI} !^index\.php$
RewriteCond %{REQUEST_URI} !^/$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
#RewriteCond %{REQUEST_URI} !^(.+)/$
RewriteRule ^(.*) url_redirector.php?url=$1 [L]
RewriteRule ^(.*).html$ $1.php [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.html [NC,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
Any ideas how can i do that? I've tried a lot of answers that I found but it's not working out for me.

Answer 1

You can refactor your rules to reduce lot of redundancy and have 2 additional rules for hiding .php and .html extensions:
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/install -d
RewriteRule !^install/ /install/ [L,NC,R=302]
RewriteRule ^(.+(?:!|\~s))$ stats.php?url=$1 [L,QSA]
RewriteRule ^(.+\~[pq])$ preview_url.php?url=$1 [L,QSA]
RewriteCond %{REQUEST_FILENAME}\.html -f
RewriteRule ^(.+?)/?$ $1.html [L]
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.+?)/?$ $1.php [L]
RewriteCond %{REQUEST_URI} !\.(php|js|css|jpe?g|png|gif|swf|ico|xml|txt|html?)$ [NC]
RewriteCond %{REQUEST_URI} !^/index\.(php|html)$ [NC]
RewriteCond %{REQUEST_URI} !^/$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* url_redirector.php?url=$0 [L,QSA]

Removing Extensions
To remove the .php extension from a PHP file you have to add the following code inside the .htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
If you want to remove the .html extension from a html file
RewriteRule ^([^\.]+)$ $1.html [NC,L]
To remove .html
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html -f
RewriteRule ^(.*)$ $1.html
Updated
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^.]+)$ $1.html [NC,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
