Register Globals will take all the keys/values in $_SERVER/$_POST/$_GET/$_COOKIES and turn each one into a variable in your script. It is equivalent to: extract($_POST); extract($_GET); extract($_COOKIE); . . . The "GPC" settings in php.ini determine the order of the above statements, in case *both* POST and GET have 'x' defined, for example. $_SERVER['USER_AGENT'] or whatever it is, is nothing more than the User-agent: header sent by your tool. You can put whatever you want in that header. What the server decides to *do* because of what you put in there is another matter. Some sites don't want to be indexed or otherwise visited by automated scripts. Follow the "robot guidelines" [Google for it] or expect to have severe issues with your webhost/carrier shutting down your account, no refund, no appeal, because other hosts are complaining about you... It's also inconceivable that wget, curl, and similar tools cannot do whatever customization you need. Those tools exist expressly for that purpose -- to be customized to automate the retrieval of data. So, almost-for-sure, you have not correctly identified your needs and assessed the tools available, and you're wasting a lot of your time inventing the wheel.
