根据条件合并多维数组
问题描述 投票：0回答：1
我有以下数组：
array (size=6)
'ID' => int 786
'userID' => int 97291
'tip_index' => string 'CARS' (length=11)
'tip_apa' => string 'calda' (length=5)
'citire' => string '2' (length=1)
'data' => string '2020-04-21 15:32:49' (length=19)
C:\wamp64\www\test2.php:19:
array (size=6)
'ID' => int 785
'userID' => int 97291
'tip_index' => string 'TRUCKS' (length=9)
'tip_apa' => string 'calda' (length=5)
'citire' => string '1' (length=1)
'data' => string '2020-04-21 15:32:49' (length=19)
C:\wamp64\www\test2.php:19:
array (size=6)
'ID' => int 784
'userID' => int 97291
'tip_index' => string 'MOTORCYCLES' (length=4)
'tip_apa' => string 'calda' (length=5)
'citire' => string '1' (length=1)
'data' => string '2020-04-21 15:32:49' (length=19)
C:\wamp64\www\test2.php:19:
array (size=6)
'ID' => int 783
'userID' => int 97291
'tip_index' => string 'CARS' (length=11)
'tip_apa' => string 'calda' (length=5)
'citire' => string '1' (length=1)
'data' => string '2020-03-21 15:32:44' (length=19)
C:\wamp64\www\test2.php:19:
array (size=6)
'ID' => int 782

'tip_apa' => string 'calda' (length=5)
'citire' => string '0' (length=1)
'data' => string '2020-03-21 15:32:41' (length=19)
C:\wamp64\www\test2.php:19:
array (size=6)

'citire' => string '0' (length=1)
'data' => string '2020-03-21 15:32:39' (length=19)
[我希望输出3个这样的多维数组，按tip_index和tip_apa分组，在其中我为每个tip_apa添加一些自定义键（例如：对于tip_apa = rece，我想添加数组data_iv_rece，number_iv_rece， data_in_rece，number_in_rece）。每个tip_apa都具有上个月的日期和值以及本月的日期和值，如下所示：
array (size=3)
'CARS' =>
array (size=2)
'rece' =>
array (size=4)
'data_iv_rece' => string '22.03.2020' (length=10)
'number_iv_rece' => string '1' (length=1)
'data_in_rece' => string '22.04.2020' (length=10)
'number_in_rece' => string '0' (length=1)
'calda' =>
array (size=4)
'data_iv_calda' => string '22.03.2020' (length=10)
'number_iv_calda' => string '1' (length=1)
'data_in_calda' => string '22.04.2020' (length=10)
'number_in_calda' => string '0' (length=1)
'TRUCKS' =>
array (size=2)
'rece' =>
array (size=4)
'data_iv_rece' => string '22.03.2020' (length=10)
'number_iv_rece' => string '1' (length=1)
'data_in_rece' => string '22.04.2020' (length=10)
'number_in_rece' => string '0' (length=1)
'calda' =>
array (size=4)
'data_iv_calda' => string '22.03.2020' (length=10)
'number_iv_calda' => string '1' (length=1)
'data_in_calda' => string '22.04.2020' (length=10)
'number_in_calda' => string '0' (length=1)
'MOTORCYCLES' =>
array (size=2)
'rece' =>
array (size=4)
'data_iv_rece' => string '22.03.2020' (length=10)
'number_iv_rece' => string '1' (length=1)
'data_in_rece' => string '22.04.2020' (length=10)
'number_in_rece' => string '0' (length=1)
'calda' =>
array (size=4)
'data_iv_calda' => string '22.03.2020' (length=10)
'number_iv_calda' => string '1' (length=1)
'data_in_calda' => string '22.04.2020' (length=10)
'number_in_calda' => string '0' (length=1)
这是最近两天一直在尝试的方法，没有获得任何预期的输出：
$userID = $_SESSION['ID'];
$info = $db->query("SELECT * FROM `indecsi` WHERE `userID` = '$userID'")->fetchAll();
$arrayInfos = array();
foreach ($info as $key => $val)
{
$month= date('m',strtotime($val['data']));
if(date($month < date('m')) && $val['tip_apa'] == 'rece')
{
$data_iv_rece = $val['data'];
$number_iv_rece = $val['citire'];
$arrayInfos += [ 'data_iv_rece' => $data_iv_rece ];
$arrayInfos += [ 'number_iv_rece' => $number_iv_rece ];
}
if(date($month == date('m')) && $val['tip_apa'] == 'rece')
{
$data_in_rece = $val['data'];
$number_in_rece = $val['citire'];
$arrayInfos += [ "data_in_rece" => $data_in_rece ];
$arrayInfos += [ "number_in_rece" => $number_in_rece ];
}
if(date($month < date('m')) && $val['tip_apa'] == 'calda')
{
$data_iv_calda = $val['data'];
$number_iv_calda = $val['citire'];
$arrayInfos += [ 'data_iv_calda' => $data_iv_calda ];
$arrayInfos += [ 'number_iv_calda' => $number_iv_calda ];
}
if(date($month == date('m')) && $val['tip_apa'] == 'calda')
{
$data_in_calda = $val['data'];
$number_in_calda = $val['citire'];
$arrayInfos += [ "data_in_calda" => $data_in_calda ];
$arrayInfos += [ "number_in_calda" => $number_in_calda ];
}
}
最后尝试获取表中的3个数组：
$consum_rece = $number_in_rece - $number_iv_rece;
$consum_calda = $number_in_calda - $number_iv_calda;
$table.= "<tr class='text-center'>";
$table.= "<td>" . str_replace('_', ' ' , $val['tip_index']) . "</td>";
$table.= "<td>" . $arrayInfos['data_in_rece'] . "</td>";
$table.= "<td>" . $arrayInfos['number_in_rece'] . "</td>";
$table.= "<td>" . $arrayInfos['data_iv_rece'] . "</td>";
$table.= "<td>" . $arrayInfos['number_iv_rece'] . "</td>";
$table.= "<td>" . $consum_rece . "</td>";
$table.= "<td>" . $arrayInfos['data_in_calda'] . "</td>";
$table.= "<td>" . $arrayInfos['number_in_calda'] . "</td>";
$table.= "<td>" . $arrayInfos['data_iv_calda'] . "</td>";
$table.= "<td>" . $arrayInfos['number_iv_calda'] . "</td>";
$table.= "<td>" . $consum_calda . "</td>";
$table.= "<td>-</td>";
$table.= "</tr>";
[尝试了多项操作，例如array_push，array_merge和array_diff以达到预期的输出，但没有运气。我觉得我已经走到一半了，无法解决问题。有什么建议吗？谢谢！

起初，您的解释让我有些困惑，但是我想我已经知道会发生什么。
假设您已经有此php数组（从MySQL或其他地方收集）：
$all_vehicles = array(
array(
'id' => 786,
'userID' => 9791,
'tip_index' => 'CARS',
'tip_apa' => 'calda',
'citire' => 2,
'data' => '2020-04-21 15:32:49'
),
array(
'id' => 785,
'userID' => 9791,
'tip_index' => 'TRUCKS',
'tip_apa' => 'calda',
'citire' => 1,
'data' => '2020-04-21 15:32:49'
),
array(
'id' => 784,
'userID' => 97291,
'tip_index' => 'MOTORCYCLES',
'tip_apa' => 'calda',
'citire' => 1,
'data' => '2020-04-21 15:32:49'
),
array(
'id' => 783,
'userID' => 97291,
'tip_index' => 'CARS',
'tip_apa' => 'calda',
'citire' => 1,
'data' => '2020-03-21 15:32:44'
),
array(
'id' => 782,
'userID' => 97291,
'tip_index' => 'TRUCKS',
'tip_apa' => 'calda',
'citire' => 0,
'data' => '2020-03-21 15:32:41'
),
array(
'id' => 781,
'userID' => 97291,
'tip_index' => 'MOTORCYCLES',
'tip_apa' => 'calda',
'citire' => 0,
'data' => '2020-03-21 15:32:39'
),
);
我的建议是滚动数组并更新所需的值。我已通过添加“ data_in _”-值来自动消除了if和else。
然后将它们添加到多维数组以在汽车，卡车和摩托车之间分配。
$ordered_vehicles = array();
foreach($all_vehicles as $val)
{
$month= date('m',strtotime($val['data']));
if($month <= date('m') && in_array($val['tip_apa'],array('rece','calda')))
{
$data = date('d.m.Y',strtotime($val['data']));
// Convert the data in the required format DD.MM.YYYY
$number = $val['citire'];
$val['data_in_'.$val['tip_apa']] = $data;
$val['number_in_'.$val['tip_apa']] = $number;
}
$ordered_vehicles[$val['tip_index']][$val['tip_apa']][] = $val;
}
[预期结果将是具有3个子数组的多维数组-汽车，卡车和摩托车。它们每个内部都有多个数组，其中包含所需的数据。
在我的情况下看起来像这样：
Array
(
[CARS] => Array
(
[calda] => Array
(
[0] => Array
(
[id] => 786
[userID] => 9791
[tip_index] => CARS
[tip_apa] => calda
[citire] => 2
[data] => 2020-04-21 15:32:49
[data_in_calda] => 21.04.2020
[number_in_calda] => 2
)
[1] => Array
(
[id] => 783
[userID] => 97291
[tip_index] => CARS
[tip_apa] => calda
[citire] => 1
[data] => 2020-03-21 15:32:44
[data_in_calda] => 21.03.2020
[number_in_calda] => 1
)
)
)
[TRUCKS] => Array
(
[calda] => Array
(
[0] => Array
(
[id] => 785
[userID] => 9791
[tip_index] => TRUCKS
[tip_apa] => calda
[citire] => 1
[data] => 2020-04-21 15:32:49
[data_in_calda] => 21.04.2020
[number_in_calda] => 1
)
[1] => Array
(
[id] => 782
[userID] => 97291
[tip_index] => TRUCKS
[tip_apa] => calda
[citire] => 0
[data] => 2020-03-21 15:32:41
[data_in_calda] => 21.03.2020
[number_in_calda] => 0
)
)
)
[MOTORCYCLES] => Array
(
[calda] => Array
(
[0] => Array
(
[id] => 784
[userID] => 97291
[tip_index] => MOTORCYCLES
[tip_apa] => calda
[citire] => 1
[data] => 2020-04-21 15:32:49
[data_in_calda] => 21.04.2020
[number_in_calda] => 1
)
[1] => Array
(
[id] => 781
[userID] => 97291
[tip_index] => MOTORCYCLES
[tip_apa] => calda
[citire] => 0
[data] => 2020-03-21 15:32:39
[data_in_calda] => 21.03.2020
[number_in_calda] => 0
)
)
)
)
您可以在那之后打印并根据需要更改数据。如果我在此过程中遗漏了一些东西，请在下面提及。干杯。
