Yet another clock abstraction...
The purpose is to decouple projects from DateTimeImmutable instantiation so that we can test things properly.
Package is available on Packagist, you can install it using Composer.
composer require lcobucci/clockMake your objects depend on the Lcobucci\Clock\Clock interface and use SystemClock or FrozenClock to retrieve the current time or a specific time (for testing), respectively:
<?phpuseLcobucci\Clock\Clock;
useLcobucci\Clock\SystemClock;
useLcobucci\Clock\FrozenClock;
functionfilterData(Clock$clock, array$objects): array
{
returnarray_filter(
$objects,
staticfunction (stdClass$object) use ($clock): bool {
return$object->expiresAt > $clock->now();
}
);
}
// Object that will return the current time based on the given timezone// $clock = SystemClock::fromSystemTimezone();// $clock = SystemClock::fromUTC();$clock = newSystemClock(newDateTimeZone('America/Sao_Paulo'));
// Test object that always returns a fixed time object$clock = newFrozenClock(
newDateTimeImmutable('2017-05-07 18:49:30')
);
// Or creating a frozen clock from the current time on UTC// $clock = FrozenClock::fromUTC();$objects = [
(object) ['expiresAt' => newDateTimeImmutable('2017-12-31 23:59:59')],
(object) ['expiresAt' => newDateTimeImmutable('2017-06-30 23:59:59')],
(object) ['expiresAt' => newDateTimeImmutable('2017-01-30 23:59:59')],
];
var_dump(filterData($clock, $objects)); // last item will be filtered
