url rewrite

URL rewriting on Linux Apache and wamp

For rewriting url on Centos Please do these steps.

1. First go to '/etc/httpd/conf/httpd.conf' and for wamp left click on wamp icon and go to Apache then httpd.conf and uncomment - #LoadModule rewrite_module modules/mod_rewrite.so and #AddModule mod_rewrite.c, so do so please remove trailing #.


2. Now Edit directory section in this file for directory /var/www/html and change 'AllowOverride none' to 'AllowOverride All'.
   
   Eg.
   Options Indexes FollowSymLinks
   AllowOverride none
   Order allow,deny
   Allow from all
   ;
   TO
   
   Options Indexes FollowSymLinks
   AllowOverride All
   Order allow,deny
   Allow from all
   ;
3. Now make a file in server root directory '/var/www/html' name .htaccess and write these line in this

Options +FollowSymlinks

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_FILENAME}\.php -f

RewriteRule ^(.*).php$ $1.html [NC]

RewriteRule ^(.*).html$  $1.php [NC]



4-Now this will replace php extension in your file to .html extension  so now if you want to open index.php then write only http://url/index.html only instead of http://url/index.php
