how to use variables in global.php in header template?

[DionDev]

i have a little hack i added to the global.php file:

// forum stats start 
  $numbersmembers=$db->query_first('SELECT COUNT(*) AS users,MAX(userid) AS max FROM user'); 
  $numbermembers=number_format($numbersmembers['users']); 
  $countposts=$db->query_first('SELECT COUNT(*) AS posts FROM post'); 
  $totalposts=number_format($countposts['posts']); 
  $countthreads=$db->query_first('SELECT COUNT(*) AS threads FROM thread'); 
  $totalthreads=number_format($countthreads['threads']); 
// forum stats end

now this works when i use the variables on a non-vb page

how do i use these variables in the header template?
