htaccess从url中删除.php和.html

I have a problem whereby google has indexed some pages with the wrong URL.

The URL they are indexing is:

http://www.example.com/user/emp.php

and HTML URL:

 http://www.example.com/login.html

I need it to redirect to:

http://www.example.com/user/emp

and HTML URL:

http://www.example.com/login

here is my .htaccess file

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

Make sure you have the mod_rewrite module is installed, Check the output of phpinfo(); function to confirm. I think the following .htaccess is fine. Place the htaccess in the root of your application.

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

Read This on how to install mod_rewrite in php

Replace it with this code in your htacess file.

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

And please remove .html and .php from all your links which you are calling for example.

    <a href="index.html">Home</a>

     To

      <a href="index">Home</a>

First check, if there exists an appropriate target ending in .html or .php, then rewrite to that URL

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

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

  # Remove .html-extension from url
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME}\.html -f
  RewriteRule ^([^\.]+)$ $1.html
