Laravel 7：根据条件计算两个日期之间的天数

Question

我陷入了复杂的计算中。我想计算两天之间的天数。但它需要检查其他两个 table 的 date 列，以确定在两个日期之间 date 是否存在。这个概念是：当用户提交休假申请时需要select开始和结束日期。两天之间的天数将保存在树叶中 table。但在保存之前需要检查两个日期之间是否有任何假期或每周假期。如果假期或每周假期匹配，则假期总数将从总天数中扣除。

每周假期：（模型名称：WorkingDay）

id	day	working_status
1	Fri	1

假日Table：（模型名称：假日）

id	date	publication_status
1	2022-05-26	1

离开Table:

id	start_date	end_date	total_days
1	2022-05-25	2022-05-28	2

控制器：

   $leave = new Leave;
   $leave->start_date = $request->start_date;
   $leave->end_date = $request->end_date;

   $start_day = date("D", strtotime($request->start_date));
   $end_day = date("D", strtotime($request->end_date));

   $start = Carbon::parse($request->start_date);
   $end = Carbon::parse($request->end_date);
   $total_days = $end->diffInDays($start);

   
   $weekly_holidays = WorkingDay::where('working_status', 0)
   ->get(['day']);

   $monthly_holidays= Holiday::where('publication_status', 1)->get(['date']);
    $total_days = //need solution here

   if($request->halfday == 1){
        $leave->total_days = 0.5;
    }
    else{
        $leave->total_days = $total_days;
    }

示例：

 WorkingDay = day = Fri
 Holiday = date = 2022-05-26
 start_date = 2022-05-25
 end_date = 2022-05-28
 total_days = 2 
 // from 25 to 28, total days is 4, but 26 is a holiday, and 27 is friday. Holiday can be multiple dates. If there is multiple holidays between start and end date, it will calculate according to this.

我不确定如何编写代码来验证这些条件。请帮助我。

欢迎来到 Whosebug 社区

您必须计算工作日、节假日和休假天数。

试试这个代码

// I assume you are getting start_date and end_date in $request.
           $request->start_date = '2022-05-25';
           $request->end_date = '2022-05-28';

           $leave = new User;
           $leave->start_date = $request->start_date;
           $leave->end_date = $request->end_date;

           $start_day = date("D", strtotime($request->start_date));
           $end_day = date("D", strtotime($request->end_date));

           // this is change
           $start = strtotime($request->start_date);
           $end = strtotime($request->end_date);
           $diff = $end - $start;
           // This will calculate days between two days including start date and end date
           $diff_in_days = floor($diff/(60*60*24)) + 1;
           // assuming Fri is holiday and get count of it
           $weekly_holidays = WorkingDay::where('working_status', 1)
           ->get(['day'])->count();
           // Get count of monthly holidays
           $monthly_holidays= Holiday::where('publication_status', 1)->get(['date'])->count();
           // your result will be 4
           $total_days = $diff_in_days - $weekly_holidays - $monthly_holidays;
           

           if($request->halfday == 1){
                $leave->total_days = 0.5;
            }
            else{
                $leave->total_days = $total_days;
            }

希望对您有所帮助！！

我已经尝试检查您想要的内容并为您做出这个答案。希望这就是您要解释的内容

Table: working_days

控制器：

public function insertLeaves(Request $request) {

    $leave = new Leave;
    $leave->start_date = $request->start_date;
    $leave->end_date = $request->end_date;

    $start_day = date("D", strtotime($request->start_date));
    $end_day = date("D", strtotime($request->end_date));

    $start = Carbon::parse($request->start_date);
    $end = Carbon::parse($request->end_date);
    $total_days = $end->diffInDays($start);

    // Gets the working days in comma seperated without the key from the database [Example: Sat, Sun, Mon, Tue, Wed, Thu] in array
    $working_days = WorkingDay::where('working_status', 0)
    ->get(['day'])->map(function($day) {
        return $day->day;
    })->toArray();

    // Gets the holidays in comma seperated dates without the key from the database [Example: 2022-05-26, 2022-05-28] in array
    $holidays= Holiday::where('publication_status', 1)->get(['date'])->map(function($date) {
        return date('Y-m-d', strtotime($date->date));
    })->toArray();

    // Get the weekend holidays we get between the start date and end date by the helper function we created 
    $weekend_holidays = $this->sumHolidays($working_days, $request->start_date , $total_days, 'weekends');

    // Get the holidays if have any between the start date and end date by the helper function we created 
    $monthly_holidays = $this->sumHolidays($holidays, $request->start_date , $total_days, 'holidays');
    
    $total_leaves = $total_days - $weekend_holidays - $monthly_holidays + 1; //need solution here;

    if($request->halfday == 1){
        $leave->total_days = 0.5;
    }
    else{
        $leave->total_days = $total_leaves;
    }
    $leave->save();

}

function sumHolidays($days, $start_date, $diff, $type) {
    $total_days = 0;
    $i = 0;
    while ($i <= $diff) {
        $tsDate = strtotime($start_date . ' ' .'+ '.$i.' days');
        if($type == 'weekends') {
            $day = date('D', $tsDate);
            if(!in_array($day, $days)) {
                $total_days++;
            }
        } elseif($type == 'holidays') {
            $date = date('Y-m-d', $tsDate);
            if(in_array($date, $days)) {
                $total_days++;
            }
        }
        $i++;
    }
    return $total_days;
}

输出示例：

Start Date = 2022-05-26
End Date = 2022-05-28
Working Days = day = ["Sat","Sun","Mon","Tue","Wed","Thu"]
Holidays = date = ["2022-05-26","2022-05-29"]
Weekend Holidays = 1
Monthly Holidays = 1
Total Days = 4
Total Leaves = 2 //As there is 1 Friday and 1 Holiday at 2022-05-26
