MessageFormatter::formatMessage -- msgfmt_format_messageQuick format message

说明

面向对象风格

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

过程化风格

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

Quick formatting function that formats the string without having to explicitly create the formatter object. Use this function when the format operation is done only once and does not need any parameters or state to be kept or when wanting to customize the output by providing additional context to ICU directly.

参数

locale

The locale to use for formatting locale-dependent parts

pattern

The pattern string to insert things into. The pattern uses an 'apostrophe-friendly' syntax; see » Quoting/Escaping for details.

values

The array of values to insert into the format string

返回值

The formatted pattern string or false if an error occurred

范例

示例 #1 msgfmt_format_message() example

<?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));
?>

示例 #2 OO example

<?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));
?>

以上例程会输出:

4,560 monkeys on 123 trees make 37.073 monkeys per tree
4.560 Affen auf 123 Bäumen sind 37,073 Affen pro Baum

示例 #3 Instructing ICU to format currency with common and with narrow currency symbol

Requires ICU ≥ 67.

<?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));

以上例程会输出:

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}
?>
