I’ve just released v1.0.0 of my [PHP Business Time](https://github.com/hughgrigg /php-business-time) library. I made this to solve my own problem that I had building my 3D pop-up card shop – calculating estimated delivery dates based on business time constraints.
It would have been simpler to just solve the exact use case I had (probably hard-coding timings and combining that with retrieving holidays from a remote source), but I thought it would be fun to generalise it and make it into a separate library.
PHP Business Time extends the Carbon date-
time library, which makes it quite intuitive to use as it behaves in the same
way. For example, you get methods like
I tried to make the library as adaptable as possible by allowing users to specify their own business time rules. The library has a reasonable default of weekdays 9am to 5pm, but you can take it quite far with configurable constraints, for example:
<?php $businessTime->setBusinessTimeConstraints( (new BusinessTime\Constraint\BetweenHoursOfDay(10, 18))->except( new BusinessTime\Constraint\BetweenTimesOfDay('13:00', '14:00') ), // 9-6 every day, with an hour for lunch. (new BusinessTime\Constraint\WeekDays())->except( new BusinessTime\Constraint\WeekDays('Thursday') ), // Week days, but let's take Thursdays off. new BusinessTime\Constraint\BetweenMonthsOfYear('January', 'November'), // No-one does any work in December anyway. new BusinessTime\Constraint\Composite\Not( new BusinessTime\Constraint\DaysOfYear('August 23rd', 'October 20th') ) // Why not take off your birthday and wedding anniversary? );
It can then perform your business time calculations based on those rules. So far there is support for:
- adding, subtracting and diffing business days and hours
- describing business times (e.g. “the weekend”)
- getting the start and end of a business day
- configurable business time rules
- fetching holiday data from webcal.fi
- business deadlines or cut-off times
I might add more features as I discover the need for them.
