How to get URL string into PHP variable

Question

Let's start with an example:

So requested URL would be: www.domain.com/product/hdd/samsung

I want to have a rewrite rule to get index.php and save everything after www.domain.com into php variable. So, substituted page would be for example www.domain.com/index.php?query=product/hdd/samsung. But I'am unable to write correct rule.

I tried this:

RewriteRule ^/(.*)$ index.php?query=$1 [NC,L]

The code above isn't working. I want to use the query in PHP code in the index.php:

if(isset($_GET["query"] )) {
   $query=$_GET["query"];
}

I find out, there is possibility to get $query via $_SERVER['QUERY_STRING'] instead of mod_rewrite, am I right?

For my PHP application is variable $query critical, because it's used for loading templates.

Questions: What solution would you recomand me? To use $_SERVER variable or mod_rewrite? If mod_rewrite, how to write correct RewriteRule?

Thank you

That rule looks fine to me. Can you test some simpler rules to verify the rewrite rule module is applied and running properly? — mellamokb

Rewrite Engine is working properly (It's on). If I use the rule above, I get 404 Error. I'am testing it on localhost (wamp server). — Daniel.P.

The best rule I have been able to write is: RewriteRule /(.*) index.php?query=$1 [NC,L], but I only get string after the second slash (if there is second slash or I get 404 error). — Daniel.P.

Try this:

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?query=$1 [NC,L]

If your site is not in your server's root dir, change RewriteBase to /some/subdir/.

Thanks a lot! Yes, Its working! But it removes parameters, e.g www.domain.com/a/b/c?sort=price. (I get index.php?query=a/b/c). I need somehow store whole string (sort=price). The best solution would be to get index.php?query=a/b/c&sort=price. I actually just need one parameter (sort). Is it even possible?

I'm quite sure I did something wrong, because I couldn't get the ?sort=price with the rewrite rule. It's like it never existed. So I thought about parsing that part with php directly. Using lafor's code, you request the correct php file, and inside that file, you get the sort part with this code: pastebin.com/vLMNSCyK . I hope it helps.
