Well Harvey, assuming you defined something like

$all_teams['Team 1'][2002] = 8;
$all_teams['Team 1'][2003] = 9;
$all_teams['Team 1'][2004] = 22;

$all_teams['Team 2'][2002] = 18;
$all_teams['Team 2'][2003] = 94;
$all_teams['Team 2'][2004] = 12;

$all_teams['Team 3'][2002] = 23;
$all_teams['Team 3'][2003] = 44;
$all_teams['Team 3'][2004] = 45;

The code

foreach ($all_teams as $team)
	foreach ($team as $year => $score)
		$all_teams['sum'][$year] += $score ;

would give you a brute force calculation of what you're looking for, 
use a

print_r($all_teams)

to get the hang of it. Note also that

array_sum($all_teams['Team 1']);

would give you the sum of 'Team 1' across all three years. Experiment  
with

$all_teams[2002]['Team 1'] = 8;
$all_teams[2002]['Team 2'] = 18;
$all_teams[2002]['Team 3'] = 23;

$all_teams[2003]['Team 1'] = 9;
$all_teams[2003]['Team 2'] = 94;
$all_teams[2003]['Team 3'] = 44;

$all_teams[2004]['Team 1'] = 22;
$all_teams[2004]['Team 2'] = 12;
$all_teams[2004]['Team 3'] = 45;

run a few more print_r's and you'll be well on your way to getting the 
hang of multidimensional arrays. And don't forget
