PHP-Mysql查询：按天显示订单数量并存储在变量中

我有一张这样结构的桌子：

table name: customer_history

id| orders | order_date (timestamp) |  status    |  
--------------------------------------------------
 1|   1    | 2012-05-29 13:11:59    |  active    |
 2|   1    | 2012-05-29 13:11:59    |  active    |
 3|   1    | 2012-05-30 13:11:59    |  canceled  |
 4|   1    | 2012-05-31 13:11:59    |  trialing  |

我需要查询数据库并计算总订单数，其中状态！=取消，对于每一天，返回一个日历月，并为每个每日总计分配一个唯一变量

昨天的订单总额大约是$day-1，两天前是$day-2，等等

编辑下面的答案

$query = "SELECT 
            COUNT(*) AS number, 
            DATE(order_date) AS order_day 
        FROM 
            customer_history
        WHERE 
            status <> 'canceled' 
        GROUP BY 
            order_day 
        ORDER BY 
            order_date 
        DESC
        LIMIT 31";

$result = mysql_query($query) or die(mysql_error());

$i = 1;
$days = array();

while($row = mysql_fetch_assoc($result)) {

      $days[$i] = $row;
      $i++;
}

echo $days[1]['number'];
echo $days[2]['number'];
echo $days[3]['number'];
echo $days[4]['number'];
echo $days[5]['number'];
echo $days[6]['number'];

然后就把结果循环一下。第一个是今天，第二个是昨天，第三个是前天，等等

包括循环/变量：

    <?php

$query = "SELECT 
                COUNT(*) AS number, 
                DATE(order_date) AS order_day 
            FROM 
                orders 
            WHERE 
                status <> 'canceled' 
            GROUP BY 
                order_day 
            ORDER BY 
                order_date 
            DESC
            LIMIT 31";

    $result = mysql_query($query);

    $i = 1;
    $days = array();

    while($row = mysql_fetch_assoc($query)
    {
        $days[$i] = $row;
        $i++;

    }

    ?>

echo$days[1]['number']为您提供今天的订单数量，$days[2]['number']为您提供昨天的订单数量，等等。您可以通过echo$days[x]['order\u day']输出实际日期。

尝试按订单日期分组的查询

循环和设置变量是给我带来麻烦的主要事情。你能详细说明一下吗？我第一次使用mysql…我在哪里指定表名customer_history？等等，也许我没有得到您的数据模型。消费者历史记录表是关于什么的？是否有普通订单表？嗯。每个客户都有一个id、订单、状态和订单日期。我每天都在试着得到很多订单。该表恰好被称为customer_history。也许我们可以使用skype？在这种情况下，尝试将“订单”更改为“客户历史记录”。

    <?php

$query = "SELECT 
                COUNT(*) AS number, 
                DATE(order_date) AS order_day 
            FROM 
                orders 
            WHERE 
                status <> 'canceled' 
            GROUP BY 
                order_day 
            ORDER BY 
                order_date 
            DESC
            LIMIT 31";

    $result = mysql_query($query);

    $i = 1;
    $days = array();

    while($row = mysql_fetch_assoc($query)
    {
        $days[$i] = $row;
        $i++;

    }

    ?>

SELECT COUNT(*) AS number, DATE(order_date) AS order_day
FROM orders WHERE status != 'canceled' 
GROUP BY order_date ORDER BY order_date DESC
