# IntlCalendar::set

(PHP 5.5.0, PECL >= 3.0.0a1)

IntlCalendar::set — Set a time field or several common fields at once

### 説明

public bool IntlCalendar::set ( int `$field` , int `$value` )
public bool IntlCalendar::set ( int `$year` , int `$month` [, int `$dayOfMonth` = NULL [, int `$hour` = NULL [, int `$minute` = NULL [, int `$second` = NULL ]]]] )

Sets either a specific field to the given value, or sets at once several common fields. The range of values that are accepted depend on whether the calendar is using the lenient mode.

For fields that conflict, the fields that are set later have priority.

This method cannot be called with exactly four arguments.

### パラメータ

`field`

  IntlCalendar の日付/時刻 フィールド定数 のいずれか。 0 から `IntlCalendar::FIELD_COUNT` までの間の整数値です。

`value`

  The new value of the given field.

`year`

  The new value for `IntlCalendar::FIELD_YEAR`.

`month`

  The new value for `IntlCalendar::FIELD_MONTH`.

`dayOfMonth`

  The new value for `IntlCalendar::FIELD_DAY_OF_MONTH`. The month sequence is zero-based, i.e., January is represented by 0, February by 1, …, December is 11 and Undecember (if the calendar has it) is 12.

`hour`

  The new value for `IntlCalendar::FIELD_HOUR_OF_DAY`.

`minute`

  The new value for `IntlCalendar::FIELD_MINUTE`.

`second`

  The new value for `IntlCalendar::FIELD_SECOND`.

### 返り値

Returns `TRUE` on success and `FALSE` on failure.

### 例

例1 IntlCalendar::set()

`<?php
ini_set('date.timezone', 'Europe/Lisbon');
ini_set('intl.default_locale', 'pt_PT');
//Calls made later have priority
$cal = new IntlGregorianCalendar(2013, 6 /* July */, 1);
$cal->set(IntlCalendar::FIELD_YEAR, 2012);
$cal->set(IntlCalendar::FIELD_EXTENDED_YEAR, 2011);
var_dump(IntlDateFormatter::formatObject($cal));
$cal = new IntlGregorianCalendar(2013, 6 /* July */, 1);
$cal->set(IntlCalendar::FIELD_YEAR, 2012);
$cal->set(IntlCalendar::FIELD_EXTENDED_YEAR, 2011);
//the time has not been recalculated yet. If we clear the extended year,
//the year set before will be used
$cal->clear(IntlCalendar::FIELD_EXTENDED_YEAR);
var_dump(IntlDateFormatter::formatObject($cal));`

上の例の出力は以下となります。

    string(20) "01/07/2011, 00:00:00"
    string(20) "01/07/2012, 00:00:00"
