Certainly something trivial, but I’m stuck!
I have a start date initialized like this:
$startDate = Carbon::createFromFormat('Y-m-d H:i', '2024-02-01 08:00');
I add days to this date to get an end date:
$qtyDays = 25;
$endDate = $startDate->addDays($qtyDays);
What I don’t understand is that the end date is calculated correctly. But the start date contains the end date.
How not to touch the start date ? Even though I read the Carbon doc, I don’t understand what’s going on.
>Solution :
Actually it is not related to Carbon itself, as Carbon is just a wrapper for the PHP DateTime class, and as long as the PHP has DateTime & DateTimeImmutable, Carbon also do has the wrapper for both.:
This class behaves the same as DateTimeImmutable except objects are modified itself when modification methods such as DateTime::modify() are called.
So you can use the CarbonImmutable like:
$startDate = CarbonImmutable::createFromFormat('Y-m-d H:i', '2024-02-01 08:00');
$qtyDays = 25;
$endDate = $startDate->addDays($qtyDays);
