README
This package provides a set of handy value objects:
- Duration
- Period
- Whitelist
Makeable is web- and mobile app agency located in Aarhus, Denmark.
Install
You can install this package via composer:
composer require makeabledk/php-value-objects
Usage
Duration
Duration provides an easy way to interact with and manipulate durations of time.
Example usages
Create a duration and display formatted
Duration::create(1,30)->toFormat(); // 01:30:00
You can also specify a custom format. Valid placeholders are: h,hh,m,mm,s,ss
Duration::$format = 'h:mm'; Duration::create(1,30)->toFormat(); // 1:30
Perform simple add/subtract calculations
Duration::create(1,30)->add(Duration::create(1,30))->toFormat(); // 03:00:00 Duration::create(1,30)->subtract(Duration::create(0,20))->toFormat(); // 01:10:00
If you are using Laravel and have a Events@getDurationAttribute() accessor that converts to Duration::class, you can even do this:
$events = Events::all(); $eventsTotalDuration = Duration::sum($events, 'duration');
Easily export as an array, and re-instantiate if needed. Great for serving client API*.
$exported = Duration::create(1,30)->toArray(); // ['seconds' => 5400, 'minutes' => 90, 'hours' => 1.5, 'formatted' => '01:30:00'] $imported = Duration::fromArray($exported);
*Note it implements illuminate/support Arrayable contract, so it automatically casts to an array for eloquent models.
Period
The Period object is great when you need to query data within a given period.
Example usages
Creating a period. Note that both start and end is optional.
$today = new Period(Carbon::today(), Carbon::tomorrow()); $future = new Period(Carbon::now()); $past = new Period(null, Carbon::now());
Manipulate on the fly
$thisWeek = new Period( Carbon::today()->previous(Carbon::MONDAY) Carbon::today()->next(Carbon::SUNDAY) ); $thisWeek->earliest(Carbon::today())->getStart(); // carbon of today $thisWeek->latest(Carbon::tomorrow())->getEnd(); // carbon of tomorrow
Easily export as an array, and re-instantiate if needed. Great for serving client API*.
$exported = (new Period(Carbon::today(), Carbon::tomorrow()))->toArray(); // ['start' => '2017-06-27 00:00:00', 'end' => '2017-06-28 00:00:00'] $imported = Duration::fromArray($exported);
*Note it implements illuminate/support Arrayable contract, so it automatically casts to an array for eloquent models.
Whitelist
Whitelist is an abstract class that you can extend to specify a certain sets of whitelisted values.
It is great to quickly whip up a Status Object that ensures you are always working with a valid status.
Example usages
Creating an OrderStatus class
class OrderStatus extends Whitelist { const VALUES = ['pending', 'accepted', 'cancelled']; }
Now you would only be able to instantiate OrderStatus with a valid status:
$accepted = new OrderStatus('accepted'); $invalid = new OrderStatus('foobar'); // throws exception
You can customize the exception thrown. For instance you could swap it for the default Symfony/Laravel '422 UnprocessableEntityExceptions'.
OrderStatus::$exceptionClass = \Symfony\Component\HttpKernel\Exception\UnprocessableEntityHttpException::class;
Now you have error handling out of the box for forms and wildcard controller methods (ie. '/orders/{status}') !
