如何从数据库查询中制作多维数组

Question

table name  =  call

表结构：

user_id | call_time | call_type| 

让我们填充它以便理解

user_id | call_time                   | call_type| 
  0     2012-04-05 07:40:58 GMT+05:00     Mised 
  0     2012-04-06 08:58:45 GMT+05:00     Out 
  0     2012-04-08 09:40:58 GMT+05:00     Incom 

我想做的事

我需要 Mysql 或等效的 Zend Framework 查询

1. call_type 的总和。也就是说，我需要知道每天有多少 Out、Missed 或 Income。

2. 每天有多少 call_time。也就是说我有 2012-04-05 那么它在数据库中有多少时间。

我需要像这样的多维数组

i =  start from first  day of the month and go up to last day of current month,

i(2012-04-01) 理解

Array
(
[ i (2012-04-01)]=>Array
    (
    [Mised ] = 67(sum of all Missed call in this date)
    [Out ] = 10(sum of all out call in this date)
    [Incom ] = 10(sum of all Incom call in this date)
    [total_call] =87 (Sum Of All)
    )

 [ i (2012-04-02) ]=>Array
    [Mised ] = 17(sum of all Missed call in this date)
    [Out ] = 2(sum of all out call in this date)
    [Incom ] = 4(sum of all Incom call in this date)
    [total_call] =23 (Sum Of All)
    )
 .
 .
 .
 .
 .
 .
 .
 .
 .
 [2012-04-30(last day current month)]=>Array
    (
    [Mised ] = 77(sum of all Missed call in this date)
    [Out ] = 72(sum of all out call in this date)
    [Incom ] = 24(sum of all Incom call in this date)
    [total_call] =173 (Sum Of All)
    )

假设我得到的总记录平均日期是 (2012-04-13 , 2012-04-17 , 2012-04-23 ,2012-04-27 , 2012-04-29) 所以我的数组将从 2012-04-01 开始，因为这在我的结果中找不到，所以我的数组将是

[2012-04-01]=>Array
    (
    [Mised ] = 0
    [Out ] = 0
    [Incom ] = 0
    [total_call] = 0 

对于 (2012-04-13) 数组将是

[2012-04-01]=>Array
    (
    [Mised ] = 10
    [Out ] = 55
    [Incom ] = 9
    [total_call] = 74 
    )

我试过的 =

public function Get_Calllogs_For_Graph($user_id, $phone_service_id){

    $curdate = new DateTime(date('Y-m-d')); 
    $current_month = date("m");
    $start_date =    date("Y-$current_month-01");
    $start_date =  $curdate->format("Y-$current_month-d H:i:s");
    $curdate = new DateTime(date('Y-m-d')); 
    $curr_date =  $curdate->format('Y-m-d H:i:s');

    $DB = Zend_Db_Table_Abstract::getDefaultAdapter();
    $select = $DB->select()
                            ->from('call', array('*', 'CAST(call_time AS DATE) AS call_time '))
                                    ->where('phone_service_id = ?', $phone_service_id)
                                    ->where('user_id = ?', $user_id)
                                    ->where(" call_time >= ?",  $start_date)
                                    ->where(" call_time<= ?",  $curr_date);
                                        $select = $DB->fetchAssoc($select);


    $records = array('Outgoing' => array(), 'Incoming' => array(), 'Missed' => array() );               
    if(count($select)){
        foreach($select as $sel){

                if(!array_key_exists($sel['call_name'], $records[$sel['call_type']])){
                    $records[$sel['call_type']][$sel['call_name']] = $this->Get_Calllogs_By_Callname($user_id, $phone_service_id, $start_date, $curr_date, $sel['call_name'], $sel['call_type']);
                }

        }
    }
    echo '<pre>';
    print_r($records);
    echo '</pre>';

    }
public function Get_Calllogs_By_Callname($user_id, $phone_service_id, $start_date, $curr_date, $call_name, $call_direction){

        $DB = Zend_Db_Table_Abstract::getDefaultAdapter();
        $select = $DB->select()
                ->from('call_log', array('COUNT(*) AS total', 'CAST(call_name AS DATE) AS call_name'))
                        ->where('phone_service_id = ?', $phone_service_id)
                        ->where('user_id = ?', $user_id)
                        ->where('call_type= ?', $call_type)
                        ->having('call_name = ? ', $call_name);
                        //->where("call_type>= ?",  $start_date)
                        //->where("call_type<= ?",  $curr_date);

                            $select = $select->query()->fetchAll();
                            if(count($select)){

                                return $select[0]['total'];

                            }else{
                                return 0;
                            }

    }

Answer 1

select call_time, call_type, count(*) as num_by_type from db
group by YEAR(call_time), MONTH(call_time), DAY(call_time), call_type.

所以你每天有每个 call_type 的总和（意味着每天最多 3 个条目）。

那么你每天做一个数组应该不会太难，总和就是三种类型之和的总和（num_by_type）。
