Question

The problem is roughly –
I need a request path like this:

host/var1/val1/var2/val2/var3/val3/…

to be overwritten like:

host/index.php?var1=val1&var2=val2&val3=var3&…

Any ideas ?

mod_rewrite isn’t going to be able to parse key/value pairs on its own. Your best bet is to have index.php help out with the parsing.

Your .htaccess file would look like this:

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite all other URLs to index.php/URL
RewriteRule .* index.php/$0 [PT,L]

Then you would use PHP at the beginning of index.php to set up the $_GET variable:

$params = explode('/', trim($_SERVER['REQUEST_URI'], '/'));

for ($i=0; $i<count($params); $i+=2) {
    $_GET[$params[$i]] = $params[$i+1];
}
