basic URL Rewriting in php issue - php

Question

I have url coming on my web page like:
www.abc.com/product_list.php?id=12&pId=1&gpId=0
I want it to show like:
www.abc.com/product_list.php/12/1/0
i know this is very basic question but i am new in php.
your help will be really appreciated.
I did experiment like this but its not working: (in my htaccess file by googling)
RewriteRule ^product_list.php /product_list.php/id=$1/pId=$2/gpId=$3 [NC]
My .htaccessfile:
RewriteEngine On
RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule ^ - [L]
RewriteCond %{HTTP_USER_AGENT} (google|yahoo|msn|aol|bing) [OR]
RewriteCond %{HTTP_REFERER} (google|yahoo|msn|aol|bing)
RewriteRule ^([^/]*)/$ hamper-anastassia.php?$1 [L]
RewriteRule index.html$ /index.php
RewriteRule about.html$ /about.php
RewriteRule products.html$ /products.php
RewriteRule partners.html$ /partners.php
RewriteRule career.html$ /career.php
RewriteRule contact.html$ /contact.php
RewriteRule products_(.*)_(.*).html$ products.php?id=$2 [L]
RewriteRule ^product_list/([0-9]+)/([0-9]+)/([0-9]+)/?$ /product_list.php?id=$1&pId=$2&gpId=$3 [NC]

Answer 1

You should remove the .php
A simple example to capture the first parameter.
RewriteRule ^products/([0-9]+)/?$ show_a_product.php?product_id=$1

Answer 2

Basically every pairing of brackets catches a variable, this is where the $1, $2, $3 comes from.
RewriteRule ^product_list.php/([0-9]+)/([0-9]+)/([0-9]+)/?$ /product_list.php?id=$1&pId=$2&gpId=$3 [NC]
As Geoffrey mentions you could go one step further and remove the need for .php but that's up to you, e.g:
RewriteRule ^product_list/([0-9]+)/([0-9]+)/([0-9]+)/?$ /product_list.php?id=$1&pId=$2&gpId=$3 [NC]
Meaning you could visit /product_list/12/1/0

Answer 3

Please remove/comment everything in your .htaccess file then type only these two statements
RewriteEngine on
RewriteRule ^products/([0-9]+)/([0-9]+)/([0-9]+)/?$ products.php?id=$1&pid=$2&gpid=$3
Your url should be like this:
/products/1/2/3
If your still getting and error check your mod_rewrite configurations
