how to pass variables to PHP binary?

[Anon]

Hi all, I would appreciate very much for a
quick help here.
My system use to run PHP as an Apache module.
And I pass in variables like this:
http://www.somesite.com/somefile.php?IDvar=1

Now my system runs PHP as a CGI. So I am
running the same script like this:

/usr/local/bin/php /somepath/somefile.php

How do I pass in the variable IDvar and value
1?

Thanks in advance.
