Mod_Rewrite / Regex to PHP URL

[Dr. No]

I am new to using mod_rewrite and am trying to rewrite a URL to pass values to
my script so that:

http://www.myclient.com/everything/animals/mammals/cats

is transformed into

http://www.myclient.com/index.php?nav[0]=everything&nav[1]=animals&nav[2]=mammals@nav[3]=cats

Specifically, I am looking for an n-ary solution to this problem. I know how to
do it for a discrete number, but how do I do this transformation when the number
of variables to go into the nav array is unknown, and how do I generate the
index number? Can any experience mod_rewrite gurus point me in the right
direction. I'm sure this is a common design pattern.

Thanks.

As far as I know you cannot, not without really messy toying with
environmental variables.

As you're using PHP, what's wrong with:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?nav=$1

And in PHP:

$nav = isset($_GET['nav']) ? explode('/',$_GET['nav']) : array();

Just use empty brackets: nav[]=everything&nav[]=animals&nav[]=mammals, php
will understand this and create the index numbers for you.

Or even:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1

And in PHP:
$_GET['nav'] = explode('/',$_SERVER['PATH_INFO']);
