Working Shift Patterns

Hi All!

I'm trying to generate a collection of dates within a date range for shift workers working x days on x days off so I can insert working day records into the db.

Right now I have this:

getShiftPattern('2022-11-25', '4', '2022-12-25');

function getShiftPattern($start, $interval, $end) {
    $datePeriod = new CarbonPeriod($start, "$interval days", $end);
    $shift = 'on';
    
    foreach($datePeriod as $date) {
      if($shift == 'on') {
        $workDays = CarbonPeriod::create($date->copy()->addDay(1), $date->copy()->addDays($interval - 1));
        echo $date->format("d/m/Y"), PHP_EOL;
        
        foreach ($workDays as $days) {
          echo $days->format("d/m/Y"), PHP_EOL;
        }
      
        echo PHP_EOL;
        $shift = 'off';
      } else {
        $shift = 'on';
      }
  
    }
    
  }

(I know it just outputs currently)

I'm just wondering if I can get input on improvements within Laravel or if i'm using CarbonPeriod correctly.

Thanks Chris

Perhaps you could use this;

use Carbon\Carbon;

$start = Carbon::parse('2022-11-25');
$end = Carbon::parse('2022-12-25');
$insert = $start->copy();

$daysOn = 4;
$daysOff =3;
$shift = [];

while($end->gt($insert)) {

  foreach(range(1,$daysOn) as $on)
  {
      if($insert->gte($end)) break;
      $shift[$insert->format('ymd')] = 'On';
      $insert->addDay();
  }

  foreach(range(1,$daysOff) as $off)
  {
      if($insert->gte($end)) break;
      $shift[$insert->format('ymd')] = 'Off';
      $insert->addDay();
  }
} 

dd($shift);
