There are two ways to do this. The easy way is to simply load any vars
passed via the URL or from a form as local vars in each script. So, I have
the following at the beginning of every script:

extract($_GET);  // load vars passed via URL into local vars.
extract($_POST);  // load vars passed via Forms into local vars.

If I pass ...?param=1 via the URL, then the extract($_GET) function will
automatically create a local var of the same name: $param

Or, you can access each variable directly. Say you pass the following via
the url:

In your script you can access the "param" var this way:


It's a pain to rejig all your scripts to work this new way, but, the
security benefits are worth it. Have a look here for more details...
