To keep everything intact, you would need to break apart the arrays into
separate arrays, sort, then put them back together.
Here is an example:
$Scores['smith']['johnsalbum'] = '99';
$Scores['doe']['doesalbum'] = '100';
$Scores['jackson']['jacksonsalbum'] = '96';
$Scores['piper']['pipersalbum'] = '400';
foreach($Scores as $art => $album){
foreach($album as $alb => $avg){
$average[$art] = $avg;
$artist[$art] = $alb;
}
}
# The next line can be changed to arsort if you want highest avg first.
asort($average);
foreach($average as $k => $v){
$newscore[$k][$artist[$k]] = $v;
}
print_r($newscore);
