As you can see the regular expression in first part of the RewriteRule command and $1 represents the first regular expression of the part of the RewriteRule and [nc] means not case sensitive.
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ products.php?id=$1
The following example will rewrite the product.php?id=5 to porduct-5.html i.e when a URL like http://localhost/product-5.html calls product.php?id=5 automatically.
SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.
RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html$ product.php?id=$2
If you like to do like http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
Suppose the you've redeveloped your site and all the new development reside inside the “new†folder of inside root folder.Then the new development of the website can be accessed like “test.com/newâ€. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new†folder.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1
