MessageFormatter::formatMessage

msgfmt_format_message

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL intl >= 1.0.0)

MessageFormatter::formatMessage -- msgfmt_format_message手早くメッセージをフォーマットする

説明

オブジェクト指向型

public static MessageFormatter::formatMessage(string $locale, string $pattern, array $values): string|false

手続き型

msgfmt_format_message(string $locale, string $pattern, array $values): string|false

明示的にフォーマッタオブジェクトを作成せずに、 手早くメッセージをフォーマットする関数です。 この関数を使用するのは、 一度きりのフォーマット処理であってパラメータや状態を保持する必要がない場合か、 追加のコンテキストを ICU に直接与えることで、出力をカスタマイズしたい場合です。

パラメータ

locale

ロケールに依存する部分をフォーマットする際に使用するロケール。

pattern

使用するパターン文字列。 パターンには、'アポストロフィに優しい' 構文を使用します。 詳細は » Quoting/Escaping を参照ください。

values

フォーマット文字列に埋め込む値の配列。

戻り値

フォーマットしたパターン文字列を返します。 エラーが発生した場合は false を返します。

例1 msgfmt_format_message() の例

<?php
echo msgfmt_format_message("en_US", "{0,number,integer} monkeys on {1,number,integer} trees make {2,number} monkeys per tree\n", array(4560, 123, 4560/123));
echo
msgfmt_format_message("de", "{0,number,integer} Affen auf {1,number,integer} Bäumen sind {2,number} Affen pro Baum\n", array(4560, 123, 4560/123));
echo
msgfmt_format_message("en", 'You finished {place, selectordinal, one {#st} two {#nd} few {#rd} other {#th}}!', ['place' => 3]), "\n";
echo
msgfmt_format_message("en",
"There {apple, plural,
=0 {are no apples}
=1 {is one apple...}
other {are # apples!}
}"
,
[
'apple' => 0]
),
"\n";

例2 オブジェクト指向の例

<?php
echo MessageFormatter::formatMessage("en_US", "{0,number,integer} monkeys on {1,number,integer} trees make {2,number} monkeys per tree\n", array(4560, 123, 4560/123));
echo
MessageFormatter::formatMessage("de", "{0,number,integer} Affen auf {1,number,integer} Bäumen sind {2,number} Affen pro Baum\n", array(4560, 123, 4560/123));
echo
MessageFormatter::formatMessage("en", 'You finished {place, selectordinal, one {#st} two {#nd} few {#rd} other {#th}}!', ['place' => 3]), "\n";
echo
MessageFormatter::formatMessage("en",
"There {apple, plural,
=0 {are no apples}
=1 {is one apple...}
other {are # apples!}
}"
,
[
'apple' => 0]
),
"\n";

上の例の出力は以下となります。

4,560 monkeys on 123 trees make 37.073 monkeys per tree
4.560 Affen auf 123 Bäumen sind 37,073 Affen pro Baum
You finished 3rd!
There are no apples

例3 通常の通貨記号と、短い形式の通貨記号を使ってフォーマットするよう、ICU に指示する

ICU ≥ 67 が必要です

<?php
echo msgfmt_format_message("cs_CZ", "{0, number, :: currency/CAD}", array(123.45));
echo
msgfmt_format_message("cs_CZ", "{0, number, :: currency/CAD unit-width-narrow}", array(123.45));

上の例の出力は以下となります。

123,45 CA$
123,45 $

Although not mentioned, single quotes (') are used internally as escaping characters. So if you want to have them in your output, you should escape them with another single quote. See examples below.

<?php

// The value {foo} should be enclosed in single quotes
echo msgfmt_format_message('en_US', "The value '{foo}' should be enclosed in single quotes", ['foo' => 'bar']);

// The value 'bar' should be enclosed in single quotes
echo msgfmt_format_message('en_US', "The value ''{foo}'' should be enclosed in single quotes", ['foo' => 'bar']);

For now, there is now way to define a default value.

<?php
echo msgfmt_format_message('fr_FR', '{distance, plural, =0{Here}other{# km}}', []);
// Show {distance}
?>
