Class yii\i18n\Formatter

Inheritance yii\i18n\Formatter » yii\base\Component » yii\base\Object
Implements yii\base\Configurable
Available since version 2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/i18n/Formatter.php

Formatter provides a set of commonly used data formatting methods.

The formatting methods provided by Formatter are all named in the form of asXyz(). The behavior of some of them may be configured via the properties of Formatter. For example, by configuring $dateFormat, one may control how asDate() formats the value into a date string.

Formatter is configured as an application component in yii\base\Application by default. You can access that instance via Yii::$app->formatter.

The Formatter class is designed to format values according to a $locale. For this feature to work the PHP intl extension has to be installed. Most of the methods however work also if the PHP intl extension is not installed by providing a fallback implementation. Without intl month and day names are in English only. Note that even if the intl extension is installed, formatting date and time values for years >=2038 or <=1901 on 32bit systems will fall back to the PHP implementation because intl uses a 32bit UNIX timestamp internally. On a 64bit system the intl formatter is used in all cases if installed.

Property Details

$booleanFormat public property

The text to be displayed when formatting a boolean value. The first element corresponds to the text displayed for false, the second element for true. Defaults to ['No', 'Yes'], where Yes and No will be translated according to $locale.

public array $booleanFormat = null

$calendar public property (available since version 2.0.7)

The calendar to be used for date formatting. The value of this property will be directly passed to the constructor of the IntlDateFormatter class.

Defaults to null, which means the Gregorian calendar will be used. You may also explicitly pass the constant \IntlDateFormatter::GREGORIAN for Gregorian calendar.

To use an alternative calendar like for example the Jalali calendar, set this property to \IntlDateFormatter::TRADITIONAL. The calendar must then be specified in the $locale, for example for the persian calendar the configuration for the formatter would be:

'formatter' => [
    'locale' => 'fa_IR@calendar=persian',
    'calendar' => \IntlDateFormatter::TRADITIONAL,
],

Available calendar names can be found in the ICU manual.

Since PHP 5.5 you may also use an instance of the IntlCalendar class. Check the PHP manual for more details.

If the PHP intl extension is not available, setting this property will have no effect.

See also:

public IntlCalendar|integer|null $calendar = null

$currencyCode public property

The 3-letter ISO 4217 currency code indicating the default currency to use for asCurrency(). If not set, the currency code corresponding to $locale will be used. Note that in this case the $locale has to be specified with a country code, e.g. en-US otherwise it is not possible to determine the default currency.

public string $currencyCode = null

$dateFormat public property

The default format string to be used to format a date. This can be "short", "medium", "long", or "full", which represents a preset format of different lengths.

It can also be a custom format as specified in the ICU manual. Alternatively this can be a string prefixed with php: representing a format that can be recognized by the PHP date()-function.

For example:

'MM/dd/yyyy' // date in ICU format
'php:m/d/Y' // the same date in PHP format
public string $dateFormat = 'medium'

$datetimeFormat public property

The default format string to be used to format a date and time. This can be "short", "medium", "long", or "full", which represents a preset format of different lengths.

It can also be a custom format as specified in the ICU manual.

Alternatively this can be a string prefixed with php: representing a format that can be recognized by the PHP date()-function.

For example:

'MM/dd/yyyy HH:mm:ss' // date and time in ICU format
'php:m/d/Y H:i:s' // the same date and time in PHP format
public string $datetimeFormat = 'medium'

$decimalSeparator public property

The character displayed as the decimal point when formatting a number. If not set, the decimal separator corresponding to $locale will be used. If PHP intl extension is not available, the default value is '.'.

public string $decimalSeparator = null

$defaultTimeZone public property (available since version 2.0.1)

The time zone that is assumed for input values if they do not include a time zone explicitly.

The value must be a valid time zone identifier, e.g. UTC, Europe/Berlin or America/Chicago. Please refer to the php manual for available time zones.

It defaults to UTC so you only have to adjust this value if you store datetime values in another time zone in your database.

Note that a UNIX timestamp is always in UTC by its definition. That means that specifying a default time zone different from UTC has no effect on date values given as UNIX timestamp.

public string $defaultTimeZone = 'UTC'

$locale public property

The locale ID that is used to localize the date and number formatting. For number and date formatting this is only effective when the PHP intl extension is installed. If not set, yii\base\Application::$language will be used.

public string $locale = null

$nullDisplay public property

The text to be displayed when formatting a null value. Defaults to '<span class="not-set">(not set)</span>', where (not set) will be translated according to $locale.

public string $nullDisplay = null

$numberFormatterOptions public property

A list of name value pairs that are passed to the intl NumberFormatter::setAttribute() method of all the number formatter objects created by createNumberFormatter(). This property takes only effect if the PHP intl extension is installed.

Please refer to the PHP manual for the possible options.

For example to adjust the maximum and minimum value of fraction digits you can configure this property like the following:

[
    NumberFormatter::MIN_FRACTION_DIGITS => 0,
    NumberFormatter::MAX_FRACTION_DIGITS => 2,
]
public array $numberFormatterOptions = []

$numberFormatterSymbols public property (available since version 2.0.4)

A list of name value pairs that are passed to the intl NumberFormatter::setSymbol() method of all the number formatter objects created by createNumberFormatter(). This property takes only effect if the PHP intl extension is installed.

Please refer to the PHP manual for the possible options.

For example to choose a custom currency symbol, e.g. U+20BD instead of руб. for Russian Ruble:

[
    NumberFormatter::CURRENCY_SYMBOL => '₽',
]
public array $numberFormatterSymbols = []

$numberFormatterTextOptions public property

A list of name value pairs that are passed to the intl NumberFormatter::setTextAttribute() method of all the number formatter objects created by createNumberFormatter(). This property takes only effect if the PHP intl extension is installed.

Please refer to the PHP manual for the possible options.

For example to change the minus sign for negative numbers you can configure this property like the following:

[
    NumberFormatter::NEGATIVE_PREFIX => 'MINUS',
]
public array $numberFormatterTextOptions = []

$sizeFormatBase public property

The base at which a kilobyte is calculated (1000 or 1024 bytes per kilobyte), used by asSize() and asShortSize(). Defaults to 1024.

public integer $sizeFormatBase = 1024

$thousandSeparator public property

The character displayed as the thousands separator (also called grouping separator) character when formatting a number. If not set, the thousand separator corresponding to $locale will be used. If PHP intl extension is not available, the default value is ','.

public string $thousandSeparator = null

$timeFormat public property

The default format string to be used to format a time. This can be "short", "medium", "long", or "full", which represents a preset format of different lengths.

It can also be a custom format as specified in the ICU manual. Alternatively this can be a string prefixed with php: representing a format that can be recognized by the PHP date()-function.

For example:

'HH:mm:ss' // time in ICU format
'php:H:i:s' // the same time in PHP format
public string $timeFormat = 'medium'

$timeZone public property

The time zone to use for formatting time and date values.

This can be any value that may be passed to date_default_timezone_set() e.g. UTC, Europe/Berlin or America/Chicago. Refer to the php manual for available time zones. If this property is not set, yii\base\Application::$timeZone will be used.

Note that the default time zone for input data is assumed to be UTC by default if no time zone is included in the input date value. If you store your data in a different time zone in the database, you have to adjust $defaultTimeZone accordingly.

public string $timeZone = null
