Apache mod_rewrite path name as query parameters?

Question

I want to use Apache's mod_rewrite in order to be able to take each folder of a path as a particular query parameter, for example consider the following:

Basic example

Url requested: http://domain.com/shoes/prada/image-1/

Page served: http://domain.com/?cid=shoes&bid=prada&pid=image-1

In this scenario, there are 3 sub-folders requested (/shoes/, /prada/ then image-1), so the first sub-folder is passed in the actual page served as cid, the second as bid and the third as pid.

Full example

However, I would also like it to serve a particular page depending on the number of sub-folders requested, e.g.

Url requested: http://domain.com/shoes/prada/

Page served: http://domain.com/shop.php?cid=shoes&bid=prada

So far all I've managed to find is regex based matching for mod_rewrite but my path's will vary a lot, which is why I would like to have conditions based on the number of folders accessed (please note, I'm not that good with regex - I reckon a wildcard character would help with this, but I wouldn't be sure where to start).

Any help on this would be greatly appreciated! This is pretty long winded, so if you need any more info for clarifying, please let me know!

@faa The 1st example was simply to show the basis of my question (e.g. parameters taken from folders), while the 2nd was to show a page being served based on the number of parameters. By "number of folders accessed" I meant the number of parameters passed with the idea that 1 folder = 1 parameter, like so /path/to/folder -> 1 = path, 2 = to, 3 = folder. — Kemebear

With a little bit of work I was able to tweak some regex and get a working rule set for what I wanted:

RewriteEngine on
RewriteRule ^(.*)/(.*)/(.*)/(.)?$ product.php?tid=$1&sid=$2&eid=$3 [L]
RewriteRule ^(.*)/(.*)/(.)?$ brand.php?tid=$1&sid=$2 [L]
RewriteRule ^(.*)/(.)?$ shop.php?tid=$1 [L]

This is a bit different to the example, however it's what I intended for in the first place.

This allows for the rewriting of url's up to four folders deep, with the "name" of each folder being given as a parameter, and each additional level of depth rewriting the url to a separate resource for example:

http://x.com/shoes/prada/2011-high-heels/ -> http://x.com/product.php?tid=shoes&sid=prada&eid=2011-high-heels
