对两个foreach循环内的总数求和

我有两个循环，一个调用代理，另一个调用一组日期。日期循环位于代理循环中。其目的是计算每个代理内部的行数。我得到的是一个总的总数，而不是我需要的每个代理的单个总数。

$company = $_SESSION['user']['company']; $sth = $db->prepare("SELECT id, firstname, lastname, company FROM users WHERE company = '".$company."' AND level = 'user' AND status = 'Active'");
    $sth->execute();
    $agents = $sth->fetchAll(); 
    foreach($agents as $name){
    $begin = new DateTime($date1);
    $end = new DateTime($date2);
    $daterange = new DatePeriod($begin, new DateInterval('P1D'), $end);                         
    foreach($daterange as $date){
        $salesdates = $date->format("Y-m-d");
        $query = "SELECT unid FROM ".$company."_automated_responses WHERE title = 'Sale' AND date LIKE '".$salesdates."%' AND agent_id = '".$name['id']."'";
        $stmt = $db->prepare( $query );
        $stmt->execute();
        $salescount = $stmt->rowCount();
        if($salescount < 10){ $bonus = 0; }
        else if($salescount < 12){ $bonus = 25; }
        else if($salescount < 14){ $bonus = 40; }
        else if($salescount < 16){ $bonus = 50; }
        else if($salescount < 18){ $bonus = 70; }
        else if($salescount < 20){ $bonus = 85; }
        else if($salescount > 19){ $bonus = 100; }                              
        $total_bonus += $bonus;
        $total_salescount += $salescount;

    }
    echo $total_salescount.' - '.$name['firstname'].' '.$name['lastname'].' - '.$total_bonus.'<br />';
}

输出:

125 - Agent 1 - 115

245 - Agent 2 - 180

387 - Agent 3 - 400

517 - Agent 4 - 540

它应该是这样的:

125 - Agent 1 - 115

120 - Agent 2 - 75

142 - Agent 3 - 220

130 - Agent 4 - 140
