PHP合并2个多维数组和求和值数组

我想合并这两个数组，并在保留

天的同时计算值
移动

第一个阵列：

array (30)
0 => array (2)
    day => "01" (2)
    movements => 49
1 => array (2)
    day => "02" (2)
    movements => 50
2 => array (2)
    day => "03" (2)
    movements => 54
...

第二个阵列：

array (30)
0 => array (2)
    day => "01" (2)
    movements => 50
1 => array (2)
    day => "02" (2)
    movements => 51
2 => array (2)
    day => "03" (2)
    movements => 41
...

因此，我期望一组数组具有相同的
日
索引和
移动的总和
：

array (30)
0 => array (2)
    day => "01" (2)
    movements => 99
1 => array (2)
    day => "02" (2)
    movements => 101
2 => array (2)
    day => "03" (2)
    movements => 95
...

任何帮助都将不胜感激。
如果阵列错过任何一天，甚至可以计算移动

<?php
$arrayFirst = [
    ['day' => '01', 'movements' => 10],
    ['day' => '02', 'movements' => 20],
    ['day' => '04', 'movements' => 40],
];

$arraySecond = [
    ['day' => '01', 'movements' => 15],
    ['day' => '03', 'movements' => 30],
    ['day' => '04', 'movements' => 45],
];

$arrColFirst = array_column($arrayFirst, 'movements', 'day');
$arrColSecond = array_column($arraySecond, 'movements', 'day');
$merrgedArray = array_merge($arrColFirst, $arrColSecond);

$result = [];
foreach ($merrgedArray as $day=> $movments) {
    $result[$day] =  [
        'day' => $day,
        'movements' => isset($arrColFirst[$day]) ? $arrColFirst[$day] + $movments : $movments,
    ];
}

sort($result);

$arr1=[['day'=>01'，'movement'=>50]，'day'=>02'，'movement'=>10]；
$arr2=[['day'=>'01'，'movement'=>20'，'day'=>02'，'movement'=>10]]；
$sum=[]；
回声'；
印刷费（$arr1）；

如果（！空（$arr1））{
$result=[]；
foreach（$arr1作为$key=>$value）{
如果（isset（$arr2[$key]['day']）&&$arr2[$key]['day']==$value['day']））{
$result['day']=$value['day']；
$result['movement']=$value['movement']+$arr2[$key]['movement']；
}
数组_push（$sum，$result）；
}
}
印刷费（$sum）；
$arr1=array_列（$arr1，null，'day'）和第二个数组。然后组合相同的索引
$arr1 = [ ['day' => '01', 'movement' => 50], ['day' => '02', 'movement' => 10] ];
$arr2 = [ ['day' => '01', 'movement' => 20], ['day' => '02', 'movement' => 10] ];

$sum = [];

echo '<pre>';
print_r($arr1);
print_r($arr2);


if(!empty($arr1)){
    $result = [];
    foreach ($arr1 as $key => $value) {
        if(isset($arr2[$key]['day']) && $arr2[$key]['day'] == $value['day']){
            $result['day'] = $value['day'];
            $result['movement'] = $value['movement']+$arr2[$key]['movement'];
        }
        array_push($sum, $result);
    }
}

print_r($sum);
