If you echo out $_SERVER['PATH_INFO'] for the URL shown below, it will
give you:
/321
Usually what you do is something like:
$pi = substr($_SERVER['PATH_INFO', 1);
$args = explode('/', $pi);
and then you'll have an array of arguments without the forward slashes.
If you're only expecting a single argument, you can possibly skip that
second step; if you want to limit the number of arguments you'll accept,
you can add a third parameter to the explode() function call.
You should still treat data passed in this way as tainted, just like
data from the query string or a form. Scrub it and validate it before
doing anything with it.
Note: to get a script called 'something' to be parsed as PHP on your
server, you'll need to do the following (assuming you're using Apache):
create a .htaccess file in that directory with the contents:
<Files ~ "(something)$">
ForceType application/x-httpd-php
</Files>
This will tell Apache that the file is a PHP script.
