I recently encountered an issue with the Carbon class in Laravel and I'm hoping someone can help me out with this. Here's the problem I'm facing:
I have a variable in my PHP code, let's say `$originalDate`, which holds the value of a date. Now, when I use Carbon to modify this date using methods like `addDays()` or `subMonth()`, I noticed that it's actually changing the value of the original variable.
I'm using Laravel's built-in Carbon class to handle dates and timezones in my application, which has been working great so far. But this unexpected behavior has left me a bit puzzled.
Here's an example of the code I'm working with:
$originalDate = Carbon::parse('2022-01-01');
$modifiedDate = $originalDate->addDays(7);
echo "Original Date: " . $originalDate->format('Y-m-d'); // Output: 2022-01-08
echo "Modified Date: " . $modifiedDate->format('Y-m-d'); // Output: 2022-01-08
As you can see, both the original and modified dates now have the same value. I was under the impression that the `addDays()` method would only modify the `$modifiedDate` variable, but it seems to be altering the original variable as well.
Am I missing something here? Is there a different way to use the Carbon class to avoid modifying the original variable?
Any help or guidance would be greatly appreciated. Thanks in advance!
