Problem to create a date with Carbon
Hello,
I have a problem with the first date which is never the $monday date. For the second date, I have no problem.
$year = $request->year;
$week = $request->week;
$monday = $this->getMondayFromWeekNumber($year, $week);
$fromDate = CarbonImmutable::createFromFormat('Y-m-d H:i:s', $monday.' 00:00:01');
$toDate = CarbonImmutable::createFromFormat('Y-m-d H:i:s', $monday.' 23:59:59')->addDays(6);
I'm looking around for 2 days without any solution.
Do you have any idea ?
Thanks a lot ;).

and this method is magical getMondayFromWeekNumber or you can show the content of it?
You can use startOfWeek btw
now()->startOfWeek()->day will give you the correct day.

@Nakov Hello ... yes it's a magic method ;).
Here is its code.
private function getMondayFromWeekNumber($year, $week, $format = 'Y-m-d')
{
$firstDayInYear = date('N', mktime(0, 0, 0, 1, 1, $year));
if ($firstDayInYear < 5) {
$shift = - ($firstDayInYear - 1) * 86400;
}
else {
$shift = (8 - $firstDayInYear) * 86400;
}
if ($week > 1) {
$weekInSeconds = ($week - 1) * 604800;
} else {
$weekInSeconds = 0;
}
$timestamp = mktime(0, 0, 0, 1, 1, $year) + $weekInSeconds + $shift;
return date($format, $timestamp);
}

I just found the solution : it wasn't a Carbon problem, it was another problem, I forgot to change a fixed test code somewhere.

by the way, this is the same as your 'magic' method;
function getMondayFromWeekNumber($year, $week, $format = 'Y-m-d')
{
return (new Carbon())->setISODate($year, $week)->format($format);
}

Wow thank you @snapey I did'nt even know that this method exists. Effectively it will be much easier.
