About

This library comprises two distinct libraries. The old Date library, and the new library. It supports most date functionality.

Installing

This library requires no other libraries.

composer require district5/date

Running Unit Tests:

Unit tests are only against the new library, within the \District5\Date namespace.

$ composer install --dev
$ ./vendor/bin/phpunit

Usage

Now dates 
<?php
// Get the utc now time
use District5\Date\Date;
use District5\Date\Tz\TzConstants;

$now = Date::now()->utc(); // A datetime object

// Get the time in London now
$now = Date::now()->london(); // A datetime object

// Get the time in ETS now
$now = Date::now()->eastern(); // A datetime object

// Get the time in a specific timezone now
$now = Date::now()->inTimezone(TzConstants::AMERICA_ANCHORAGE); // A datetime object

// Get the epoch as a DateTime
$epoch = Date::epoch();
Modify a date

General:

<?php

use District5\Date\Date;

$date = Date::now()->utc();

// Set the date to the 21st March 2016
$newDate = Date::modify($date)->setDate(21, 3, 2015);

// Set the date to the 21st March 2016 in place -  The original object changes (but is also returned)
Date::modify($date, false)->setDate(21, 3, 2015);

// Set the time to the 18:16:02 and 1 microsecond
$newDate = Date::modify($date)->setTime(18, 56, 2, 1);

// Set the time to the 18:16:02 and 1 microsecond in place -  The original object changes (but is also returned)
Date::modify($date, false)->setTime(18, 56, 2, 1);

// Set the hours of the time to 10
$newDate = Date::modify($date)->setHours(10)

// Set the hours of the time to 10 in place -  The original object changes (but is also returned)
Date::modify($date, false)->setHours(10)

// Set the minutes of the time to 10
$newDate = Date::modify($date)->setMinutes(10)

// Set the minutes of the time to 10 in place -  The original object changes (but is also returned)
Date::modify($date, false)->setMinutes(10)

// Set the seconds of the time to 10
$newDate = Date::modify($date)->setSeconds(10)

// Set the seconds of the time to 10 in place -  The original object changes (but is also returned)
Date::modify($date, false)->setSeconds(10)

// Set the microseconds of the time to 10
$newDate = Date::modify($date)->setMicroseconds(10)

// Set the microseconds of the time to 10 in place -  The original object changes (but is also returned)
Date::modify($date, false)->setMicroseconds(10)

// Apply a string modified to at DateTime
$newDate = Date::modify($date)->withString('-5 seconds');
// Apply a string modified to at DateTime in place -  The original object changes (but is also returned)

Date::modify($date, false)->withString('-5 seconds');

// Convert a string datetime to a DateTime object
$dateTime = Date::input('05/02/2020')->fromYMDHIS($dateSeparator = '-', $timeSeparator = ':'); // defaults to '-' and ':'

// And many more!
Recurring dates (ie, Christmas, Star Wars day etc...) 
<?php
use District5\Date\Date;

Sorting dates 
<?php
use District5\Date\Date;

$str = $output->getDaySuffix(); // 'th' - The day suffix, for example: rd, th, st etc

$int = $output->getYear(); // 2021 - The integer year of this date

$int = $output->getMonth(); // 1 - The integer month of this date

$int = $output->getWeek(); // 2 - The integer week number, for example 52 (some years have 53)

$int = $output->getDay(); // 13 - The integer day of the month

$str = $output->getHourMinutes(); // '14:53' - The string of HH:MM time

$str = $output->getHourMinutesSeconds(); // '14:53:59' - The string of HH:MM:SS time

$int = $output->getHour(); // 14 - The integer hour of this date

$int = $output->getMinutes(); // 53 - The integer minutes of this date

$int = $output->getSeconds(); // 59 - The integer seconds of this date

$int = $output->getMicroseconds(); // 999000 - The integer microseconds of this date

$int = $output->getMilliseconds(); // 999 - The integer milliseconds of this date

$str = $output->toTimeHM(':'); // '14:53' - The string of HH:MM time using the default separator (can be changed)

$str = $output->toTimeHMS(':'); // '14:53:59' - The string of HH:MM:SS time using the default separator (can be changed)

$str = $output->toYMD(true, '-'); // '2021-01-13' - The string of the date as YYYY-MM-DD using the default separator (can be changed)

$str = $output->toDMY(true, '-'); // '13-01-2021' - The string of the date as DD-MM-YYYY using the default separator (can be changed)

$str = $output->toMDY(true, '-'); // '01-13-2021' - The string of the date as MM-DD-YYYY using the default separator (can be changed)

$str = $output->toTimestamp(true); // '1610549639' - The string (or int if false passed) of the DateTime

$str = $output->toUnixTimestamp(true); // '1610549639' - The string (or int if false passed) of the DateTime

$int = $output->toTimestamp(false); // int(1610549639) - The integer timestamp because false is passed.

$int = $output->toUnixTimestamp(false); // int(1610549639) - The integer timestamp because false is passed.

$str = $output->toMicrosecondTimestamp(true); // '1610549639.000999' - Microsecond timestamp. A string because true is passed

$str = $output->toMillisecondTimestamp(true); // '1610549639.000' - Millisecond timestamp. A string because true is passed

$float = $output->toMicrosecondTimestamp(false); // float(1610549639.001) - Microsecond timestamp. A float because false is passed

$float = $output->toMillisecondTimestamp(false); // float(1610549639) - Millisecond timestamp. A float because false is passed

$str = $output->toISO8601(); // '2021-01-13T14:53:59+0000' - The ISO 8601 format of the DateTime
Old library (`District5\Utility\Date` namespace)

PHP Dates

See autocomplete for full list of functions:

\District5\Utility\Date::NowPlusXHours(5);

MongoDB UTCDateTime

See autocomplete for function signatures:

use District5\Utility\DateMongo;


DateMongo::MongoUTCDateTimeToPHPDateTime();

DateMongo::MongoUTCDateTimeToTimestampInt();

DateMongo::MongoUTCDateTimeToTimestampMillisInt();

DateMongo::PHPDateTimeToMongoUTCDateTime();

Stopwatch

The stopwatch class can be instantiated and used to measure time at intervals from stopwatch start:

$stopwatch = new \District5\Utility\Stopwatch();
$stopwatch->start();

...

$secondsPassed = $stopwatch->secondsPassed();

You can also set a max time so a boolean check can be made to see if that time has passed. This is useful when working with cron tasks where there is a maximum execution time.

$maxTimeSeconds = 300;

$stopwatch = new \District5\Utility\Stopwatch($maxTimeSeconds);
$stopwatch->start();

while (!$stopwatch->hasMaxTimePassed())
{
    // do some work
}

In the above example you should take into account how long an item could take to process an iteration in the while loop to set the max seconds allowed less than the max time a cron can run - time to process 1 loop iteration.

Timezone

Maintains a list of timezones, their offsets from UTC and a human friendly label. See autocomplete for full list of functions.
