Array empty outside foreach loop

Question

I got the following code:

$hostUptimesSum = [];
foreach($hostIDs as &$hostID)
  {
    $hostUptimeDetailsQuery = "some query";
    $resultHostUptimeDetails = mysql_query($hostUptimeDetailsQuery);
    $rowHostUptimeDetails = mysql_fetch_assoc($resultHostUptimeDetails);
    $totalTime = $rowHostUptimeDetails['UP_T'] + $rowHostUptimeDetails['DOWN_T'] + $rowHostUptimeDetails['UNREACHABLE_T'] + $rowHostUptimeDetails['UNDETERMINED_T'] + $rowHostUptimeDetails['MAINTENANCE_T'];

    array_push($hostUptimes, $rowHostUptimeDetails);

    $hostUptimesSum['UP_A'] += $rowHostUptimeDetails['UP_A'];
    $hostUptimesSum['UP_T'] += $rowHostUptimeDetails['UP_T'];
    $hostUptimesSum['DOWN_A'] += $rowHostUptimeDetails['DOWN_A'];
    $hostUptimesSum['DOWN_T'] += $rowHostUptimeDetails['DOWN_T'];
    $hostUptimesSum['UNREACHABLE_A'] += $rowHostUptimeDetails['UNREACHABLE_A'];
    $hostUptimesSum['UNREACHABLE_T'] += $rowHostUptimeDetails['UNREACHABLE_T'];
    $hostUptimesSum['UNDETERMINED_T'] += $rowHostUptimeDetails['UNDETERMINED_T'];
    $hostUptimesSum['MAINTENANCE_T'] += $rowHostUptimeDetails['MAINTENANCE_T'];
    $hostUptimesSum['TOTAL'] += $totalTime;




     array_push($values, array($hostID['host_name'], 
 round($rowHostUptimeDetails['UP_T']/$totalTime*100,2)."%",$rowHostUptimeDetails['UP_A'],
    round($rowHostUptimeDetails['DOWN_T']/$totalTime*100,2)."%",
    $rowHostUptimeDetails['DOWN_A']
    ,round($rowHostUptimeDetails['UNREACHABLE_T']/$totalTime*100,2)."%",
    $rowHostUptimeDetails['UNREACHABLE_A'],
    round($rowHostUptimeDetails['MAINTENANCE_T']/$totalTime*100,2)."%",
    round($rowHostUptimeDetails['UNDETERMINED_T']/$totalTime*100,2)."%",));

}
var_dump($hostUptimesSum);
$data = array(
    'UP' => $hostUptimesSum['UP_T'],
    'DOWN' => $hostUptimesSum['DOWN_T'],
    'UNREACHABLE' => $hostUptimesSum['UNREACHABLE_T'],
    'SCHEDULED DOWNTIME' => $hostUptimesSum['MAINTENANCE_T'],
    'UNDETERMINED' => $hostUptimesSum['UNDETERMINED_T']
);

The $hostUptimesSum array is declared outside the foreach loop. If I perform var_dump on the array inside foreach loop I can see values adding up correctly but when I call var_dump outside the loop I get nothing.

I am completely out of ideas at the moment.

Edit: I added all the code related to this particular array.
