Question

我有一个mysql查询，它按时间间隔计算调用次数（使用Select Case和Count）。我对每种类型的呼叫执行查询，在这种情况下是NP_call和其他呼叫。我正在尝试将我生成的数组组合成一个数组，其中包含每个时间间隔的调用计数。我在组合数组时遇到了困难。这是我将用于NP_calls的查询

SELECT CASE WHEN calldate between 08:00:00 and 08:29:59 then 08:00 (etc ...)
END AS interval
Count(channel) as NP_calls
FROM calls
WHERE cid like '%np%'
GROUP BY calldate

我的数组如下：$ arr3将是最终的组合数组：

    $arr1 = Array ( [0] => Array ( [interval] => 07:00 [NP_calls] => 1) 
                    [1] => Array ( [interval] => 08:00 [NP_calls] => 2) 
                    [2] => Array ( [interval] => 08:30 [NP_calls] => 3) 
                    [3] => Array ( [interval] => 10:00 [NP_calls] => 11) 
                    [4] => Array ( [interval] => 11:00 [NP_calls] => 2)) 

    $arr2 = Array ( [0] => Array ( [interval] => 07:00 [Other_calls] => 8)   
                    [1] => Array ( [interval] => 07:30 [Other_calls] => 10)                 
                    [2] => Array ( [interval] => 09:00 [Other_calls] => 11)   
                    [3] => Array ( [interval] => 10:00 [Other_calls] => 14) 
                    [4] => Array ( [interval] => 10:30 [Other_calls] => 16))

    $arr3 = Array ( [0] => Array ( [interval] => 07:00 [NP_calls] => 1     
                          [Other_calls] => 8 ) 
                    [1] => Array ( [interval] => 07:30 [Other_calls] => 10 ) 
                    [2] => Array ( [interval] => 08:00 [NP_calls] => 2) 
                    [3] => Array ( [interval] => 08:30 [NP_calls] => 3 ) 
                    [4] => Array ( [interval] => 09:00 [Other_calls] => 11 ) 
                    [5] => Array ( [interval] => 10:00 [NP_calls] => 11  
                                   [Other_calls] => 14 ) 
                    [6] => Array ( [interval] => 10:30 [Other_calls] => 16 ) 
                    [7] => Array ( [interval] => 11:00 [NP_calls] => 2)

在表格中，这是我想要得到的结果**通知在09:30没有任何内容，因为当时没有电话。

    interval    NP_calls    Other_calls
    07:00       1           8   
    07:30                   10
    08:00       2           
    08:30       3           
    09:00                   11
    10:00       11          14
    10:30                   16              
    11:00       2

如果有人能够在查询中弄清楚如何做得更好！

Answer 1

在MySQL Side，您可以使用内部联接或左联接来组合表数据

http://www.w3schools.com/sql/sql_join_left.asp

http://www.w3schools.com/sql/sql_join_inner.asp

OR

在PHP端，您可以使用array_merge函数组合两个不同的数组

Answer 2

你可以循环遍历两个数组并使用interval作为键创建组合数组，如下所示：

foreach ($arr1 as $np) {
    $combined[$np['interval']]['NP_calls'] = $np['NP_calls'];
}
foreach ($arr2 as $other) {
    $combined[$other['interval']]['Other_calls'] = $other['Other_calls'];
}

这将生成如下组合数组：

$combined = array(
    '07:00' => array('NP_calls' => 1, 'Other_calls' => 8),
    '07:30' => array('Other_calls' => 10),
    '08:00' => array('NP_calls' => 2),
    '08:30' => array('NP_calls' => 3), 
    '09:00' => array('Other_calls' => 11), 
    '10:00' => array('NP_calls' => 11, 'Other_calls' => 14),
    '10:30' => array('Other_calls' => 16), 
    '11:00' => array('NP_calls' => 2)
);

结合多维数组
