如何使用htaccess或其他技术从url中删除多个查询字符串变量

Question

My website has dynamic pages such as

http://www.example.com/detailpage.php?sn=1%20&&%20database=news
http://www.example.com/detailpage.php?sn=1%20&&%20database=article
http://www.example.com/detailpage.php?sn=1%20&&%20database=interview

and many other

I want to remove or hide query string variable from url and display as

http://www.krishisansar.com/detailpage/news/1
http://www.krishisansar.com/detailpage/article/1

Is it possible to change querystring as slash ? if not, how to remove & and make as

/news=1 or /news=2, 
/article=1 or /article=2 .

By this, I can validate from w3c.

You can use this code in your DOCUMENT_ROOT/.htaccess file:

Options -MultiViews
RewriteEngine On
RewriteBase /

RewriteCond %{THE_REQUEST} /detailpage\.php\?sn=([^\s&]+)&database=([^\s&]+) [NC]
RewriteRule ^ detailpage/%2/%1? [R=302,L,NE]

RewriteRule ^detailpage/(\w+)/(\d+)/?$ detailpage.php?sn=$2&database=$1 [L,QSA,NC]
