Not sure exactly what the goal is, and there may be a much better way
to do it, but if I understand correctly then this might work:

function write_globals() {
  $command = ' global $bar1, $bar2; '; 
  return $command;
}
function foo1() {
  $command = write_globals();
  eval( $command );

  // code
}

Be extremely careful with eval() to ensure that no user input finds
its way into the $command string, otherwise somebody could execute
arbitrary php code within your application.

Like I said, there's probably a better way to do whatever you are
trying to do....
