Laravel 7：计算有条件的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表中的

date

列，在两个日期之间

date

是否存在。其概念是：用户提交休假申请时需要选择开始和结束日期。两天之间的天数将保存在 leaves 表中。但在保存之前需要检查两个日期之间是否有假期或每周假期。如果假期或每周假期匹配，则将从总天数中扣除假期总数。

每周假期：（型号名称：WorkingDay）

id	日	工作状态
1	周五	1

假期表：（型号名称：假期）

id	日期	出版物状态
1	2022-05-26	1

离开餐桌：

id	开始日期	结束日期	总天数
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。

我已尝试准确检查您想要的内容，并为您做出了这个答案。希望这就是您想要解释的内容

表：工作日

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

看看这个

public function store(Request $request) {

    // find the number of days between two dates
    $start_date = Carbon::parse(request('start_date'));
    $end_date = Carbon::parse(request('end_date'));

    $days = $start_date->diffInWeekdays($end_date);

}else

        ->update(['total_leave_taken' => $leaves]);

    }

    $leaveEntitlement = LeaveBalance::getNumOfLeaveEntitlment();

    $total_leave_balance = (int)$leaveEntitlement - (int)$leaves;
    // dd($leaveEntitlement);

    }

Answer 3

您必须计算工作日、假期和休假天数。

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;
    }
