URL use "/" instead of "?" to send variables

Hi,
In normal php, We use ?id=123 to send variable through URL.

So, the URL would be www.example.com/page.php?id=123 and then we use $_REQUEST['id'] to receive the variable on another page.

But my question is, if I use "/" instead of "?" (Ex: www.example.com/page.php/id/123), then how to receive the "id" on page.php.

$_REQUEST['id'] doesn't works in this case.

Thank you in advance

 

You do it via mod_rewrite

a rule similar to this one would be used.

RewriteCond ^page.php/(a-z*)/(0-9*)$ page.php?$1=$2

Code (markup):

 

Wow, this is exactly i was looking for.
Thanks in bunch stephan

 

Also you can parse $_SERVER['REQUEST_URI'] for more complex url setup without complex and long mod_rewrite

 

i'll definitely use. Thanks
