New createFromFormat for CarbonInterval

[xfudox]

This would be a proposal, not an issue, but i wasn't sure on where to put it.

The proposal is to implement a createFromFormat($format, $time) constructor for CarbonInterval as Carbon object already has, this to better handle MySQL (and others DBMS) time data type or other string representations of time intervals.

It is tedious to use a long

Carboninterval::create(0, 0, 0, 0, 1, 30, 0, 0)

or even a

Carboninterval::hours(1)->minutes(30)

since i have to split the original string into several variables, and eventyally calculate days, weeks and so on.

It would be more readable and user friendly something like

Carboninterval::createFromFormat('H:i', '1:30')

Hi, this sounds very interesting and pretty simple.

I can already give you a macro that would do exactly that:

CarbonInterval::macro('createFromFormat', static function (string $format, string $interval) {
  return Carbon::createFromFormat('!'.ltrim($format, '!'), $interval, 'UTC')->diffAsCarbonInterval(
    Carbon::parse('1970-01-01 00:00:00', 'UTC')
  );
});

echo Carboninterval::createFromFormat('H:i', '01:30');

If you want to propose it as a core method of CarbonInterval, I would release it in next minor release.

Note: to be strict H should be 01.

Will be released in 2.27.0
