我需要有关此代码的帮助，我设法从 mysql 数据库中提取数据并将它们转换为 Highcharts 所需的格式。
<?php
$query =mysql_query("select
date_format(connect_time,'%Y-%m-%d %H %i') AS date,
Customers.name as customer,
Sum(duration) as secondes
from CDR_Vendors
inner join Customers on (CDR_Vendors.i_customer = Customers.i_customer)
where
i_vendor='32'
and
connect_time between '2010-09-01 00:00:00' and '2010-09-01 00:10:00'
group by date
ORDER BY date", $link) or die(mysql_error());
$row = mysql_fetch_assoc($query);
$customer[] = $row['customer'];
$json_secondes = array();
$json_date = array();
do{
$secondes[] = $row['secondes'];
array_push($json_secondes, $row['secondes']);
array_push($json_date, $row['date']);
}
while($row = mysql_fetch_assoc($query));
//echo json_encode($json_secondes,$row);
//echo json_encode($json_date,$row);
//echo join($secondes, ', ');
?>

此代码的问题在于它只显示来自单个客户的数据，因此查询返回来自多个客户的数据。
这种方法很好还是有另一种更简单的方法可以做到这一点？
