Method Detail

__construct() public

__construct(mixed $time, mixed $tz)

Create a new Date instance.

You can specify the timezone for the $time parameter. This timezone will not be used in any future modifications to the Date instance.

The $timezone parameter is ignored if $time is a DateTimeInterface instance.

Date instances lack time components, however due to limitations in PHP's internal Datetime object the time will always be set to 00:00:00, and the timezone will always be UTC. Normalizing the timezone allows for subtraction/addition to have deterministic results.

Parameters

string|int|\DateTimeInterface|null $time optional

Fixed or relative time

\DateTimeZone|string|null $tz optional

The timezone in which the date is taken. Ignored if $time is a DateTimeInterface instance.

__debugInfo() public

i18nFormat() public

i18nFormat(mixed $format, mixed $timezone, mixed $locale)

Returns a formatted string for this time object using the preferred format and language for the specified locale.

It is possible to specify the desired format for the string to be displayed. You can either pass IntlDateFormatter constants as the first argument of this function, or pass a full ICU date formatting string as specified in the following resource: http://www.icu-project.org/apiref/icu4c/classSimpleDateFormat.html#details.

Additional to IntlDateFormatter constants and date formatting string you can use Time::UNIX_TIMESTAMP_FORMAT to get a unix timestamp

Examples

$time = new Time('2014-04-20 22:10');
$time->i18nFormat(); // outputs '4/20/14, 10:10 PM' for the en-US locale
$time->i18nFormat(\IntlDateFormatter::FULL); // Use the full date and time format
$time->i18nFormat([\IntlDateFormatter::FULL, \IntlDateFormatter::SHORT]); // Use full date but short time format
$time->i18nFormat('yyyy-MM-dd HH:mm:ss'); // outputs '2014-04-20 22:10'
$time->i18nFormat(Time::UNIX_TIMESTAMP_FORMAT); // outputs '1398031800'

You can control the default format used through Time::setToStringFormat().

You can read about the available IntlDateFormatter constants at https://secure.php.net/manual/en/class.intldateformatter.php

If you need to display the date in a different timezone than the one being used for this Time object without altering its internal state, you can pass a timezone string or object as the second parameter.

Finally, should you need to use a different locale for displaying this time object, pass a locale string as the third parameter to this function.

Examples

$time = new Time('2014-04-20 22:10');
$time->i18nFormat(null, null, 'de-DE');
$time->i18nFormat(\IntlDateFormatter::FULL, 'Europe/Berlin', 'de-DE');

You can control the default locale used through Time::setDefaultLocale(). If empty, the default will be taken from the intl.default_locale ini config.

Parameters

string|int|int[]|null $format optional

Format string.

string|\DateTimeZone|null $timezone optional

Timezone string or DateTimeZone object in which the date will be displayed. The timezone stored for this object will not be changed.

Parameters

\DateTimeInterface|string|int $time optional

The strtotime compatible string to parse

\DateTimeZone|string|null $tz optional

The DateTimeZone object or timezone name.

Returns

static

parseDate() public static

parseDate(string $date, mixed $format)

Returns a new Time object after parsing the provided $date string based on the passed or configured date time format. This method is locale dependent, Any string that is passed to this function will be interpreted as a locale dependent string.

When no $format is provided, the wordFormat format will be used.

If it was impossible to parse the provided time, null will be returned.

Example:

$time = Time::parseDate('10/13/2013');
 $time = Time::parseDate('13 Oct, 2013', 'dd MMM, y');
 $time = Time::parseDate('13 Oct, 2013', IntlDateFormatter::SHORT);

Unlike DateTime, the time zone of the returned instance is always converted to $tz (default time zone if null) even if the $time string specified a time zone. This is a limitation of IntlDateFormatter.

If it was impossible to parse the provided time, null will be returned.

Example:

$time = Time::parseDateTime('10/13/2013 12:54am');
 $time = Time::parseDateTime('13 Oct, 2013 13:54', 'dd MMM, y H:mm');
