I never use the p2p search engine. I use google.

Because of google's "site search" feature, p2p doesn't actually need to
license the search software from google (or buy their search appliance).
See above. =)

Hmmm... it sounds familiar. Try this:
<?php // register_globals.php
$globals_order = array('ENV', 'GET', 'POST', 'COOKIE', 'SESSION');
foreach($globals_order as $global)
$sgname = "_$global"; // superglobal name, e.g. _GET, _POST
$sg = &$GLOBALS[$sgname]; // is a reference to actual
foreach($sg as $key=>$value)
$GLOBALS[$key] = $value; // global is a *copy*
To use this, simply require_once() this file at the top of any script that
needs register_globals="on" functionality:
Hope this helps!
