I have never edited the .htaccess file before so sorry for my awful attempt
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/index\.php$
RewriteCond %{QUERY_STRING} ^id=([0-9]*)$
RewriteRule ^(.*)$ http://example.site/index/%1 [R=302,L]
I am tryting to rewrite http://ex.com/shop/?s=sa to look like http://ex.com/shop/sa
RewriteCond %{THE_REQUEST} "\s/shop/\?s=(\w*)\s"->RewriteRule ^ "http://example.site/shop/%1?" [R=302,L]
