		$scrubList = array('HTTP_GET_VARS', 'HTTP_POST_VARS', 'HTTP_COOKIE_VARS', 'HTTP_POST_FILES');
		foreach ($scrubList as $outer) 
		{
			foreach ($scrubList as $inner) 
			{
				if (isset(${$outer}[$inner])) 
				{
					unset(${$outer}[$inner]);
				}
			}
		}  
		....some php code...
		/* End Security Fix */
		extract($_GET);
