比较并组合PHP中的2个数组

php arrays

比较并组合PHP中的2个数组,php,arrays,Php,Arrays,我有两个数组，第一个数组是当前月份内的天数，另一个数组来自数据库结果。我想创建一个新数组，其中来自数据库的结果按id和全名分组，然后在其中组合天数数组 //days with month array $current_month = array ( '2020-07-01', '2020-07-02', '2020-07-03', '2020-07-04', '2020-07-05',

            'no'       => 5
        )
    );

现在，我已经创建了一个代码，它将根据id、全名和月份的天数对数组进行分组，然后在匹配日期时尝试添加“否”值，如果不匹配，“否”为0

我的问题是只附加了一个值，其余值在每个组中都变为零，比如2020-07-03应该有一个值为3的对（$data的键0），但它变为零。从按“id”和“fullname”分组的数据库结果数组中，只有2020-07-13的对值为5（$data的键4）

对不起，我说的是英语，我希望你们都明白我的意思

试试这个：


$temp = [];
$days = array_fill_keys($current_month, 0);
foreach ($data as $item) {
    $id         = $item['id'];
    $fullname   = $item['fullname'];
    $no         = $item['no'];
    $r_date     = explode(' ', $item['date'])[0];

    $dates = $days;

    if (! $temp[$id][$fullname]) {
        $temp[$id][$fullname] = $days;
    }

    $temp[$id][$fullname][$r_date] = $no;
}

echo '=========================================';
print_r($temp);

我删除了N^2问题（嵌套循环）。我认为这个示例完成了您要查找的内容（显示每天相对于用户id值的“否”值）。

代码缺少的内容检查现有值。这里有一个代码可以解决您的问题

几乎是答案，组合日期应该是这样[0]=>“2020-07-01”[1]=0，而不是这样[2020-07-01]=0，但仍然感谢您的回复
