$query4 = "SELECT bill.agent_id, bill.date, SUM(bill.amount + bill.cheque) AS total, bill_agents.id,bill_agents.name ".
              "FROM bill, bill_agents ".
              "WHERE bill.agent_id = bill_agents.id AND YEAR(date)  = YEAR(CURDATE()) AND MONTH(date) = MONTH(CURDATE()) ". 
              "GROUP BY bill.date , bill.agent_id  ".
              "ORDER BY bill.date ASC";

Php Code

<?php 

    $query4 = "SELECT bill.agent_id, bill.date, SUM(bill.amount + bill.cheque) AS total, bill_agents.id,bill_agents.name ".

              "ORDER BY bill.date ASC";

    $result4 = mysql_query($query4) or die('Error, query failed1'); 
    if  (mysql_num_rows($result4)>0){
    mysql_data_seek($result4, 0);   

?>
  <?php while($row4 = mysql_fetch_array($result4, MYSQL_ASSOC)){?>
  <?php $date =    $row4['date'];

    $var = $date;
    $date = date("d-m-Y", strtotime($var) );
    $date=substr($date, 0, -8); 

    echo $date;

问题出在 Group By 部分：

尝试此查询：

$query4 = "SELECT bill.agent_id, bill.date, SUM(bill.amount + bill.cheque) AS total,
bill_agents.id,bill_agents.name ".
"FROM bill, bill_agents ".
"WHERE bill.agent_id = bill_agents.id AND YEAR(date)  = YEAR(CURDATE()) 
AND MONTH(date) = MONTH(CURDATE()) ". 
"GROUP BY DATE(bill.date) , bill.agent_id ".
"ORDER BY bill.date ASC";

Php Mysql Group由similer 2领域？
