I don't get why you can't just use a Registry pattern here. Having a 
simpleRegistry object that you can throw data into and pull out of not only 
allows you to keep your global space clean, but allows you to encapsulate 
your "global" data and access it via a simple interface. Sure, it might be a 
few extra keystrokes to type something akin to: Registry::get('var1'); but, 
personally, I think the trade-off is well worth it.

simple example class:
--------------------
class Registry {
     protect function __construct() {} // no instantiation - static class
     static protected $data = array();

     static public function get($name) {
         return (isset(self::$data[$name]) ? self::$data[$name] : null);
     }

     static public function set($name, value) {
         self::$data[$name] = $value;
     }
}
--------------------

summary: why "fix" what ain't really broke...?

Cheers!,
