又一个时钟抽象...

目的是将项目从 DateTimeImmutable 实例化中解耦，以便我们可以正确地进行测试。

安装

此包可在 Packagist 上找到，您可以使用 Composer 进行安装。

composer require lcobucci/clock

用法

使您的对象依赖于 Lcobucci\Clock\Clock 接口，并分别使用 SystemClock 或 FrozenClock 获取当前时间或特定时间（用于测试）。

<?php

use Lcobucci\Clock\Clock;
use Lcobucci\Clock\SystemClock;
use Lcobucci\Clock\FrozenClock;

function filterData(Clock $clock, array $objects): array
{
    return array_filter(
        $objects,
        static function (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 = new SystemClock(new DateTimeZone('America/Sao_Paulo'));

// Test object that always returns a fixed time object
$clock = new FrozenClock(
    new DateTimeImmutable('2017-05-07 18:49:30')
);

// Or creating a frozen clock from the current time on UTC
// $clock = FrozenClock::fromUTC();

$objects = [
    (object) ['expiresAt' => new DateTimeImmutable('2017-12-31 23:59:59')],
    (object) ['expiresAt' => new DateTimeImmutable('2017-06-30 23:59:59')],
    (object) ['expiresAt' => new DateTimeImmutable('2017-01-30 23:59:59')],
];

var_dump(filterData($clock, $objects)); // last item will be filtered
