Convert all get parameters in one

I have .htaccess file with the code:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) ?p=开发者_如何学Python$1  [L] 

but I want it to convert not only URI string to a get parameter p but also all other get parameters to p, in other words:

domain.com/somewhere/somepage.html?foo=2 ---->

domain.com/?p=urlencoded(somewhere/somepage.html?foo=2)

How can I do that?

Use following code in .htaccess file

Options +FollowSymlinks -MultiViews
RewriteEngine on

RewriteCond %{QUERY_STRING} !^p= [NC]
RewriteRule . /?p=%{REQUEST_URI}?%{QUERY_STRING} [L]

Since NE flag is not provided here so mod_rewrite engine will encode your original URI before internally redirecting.
