NumberFormatter::formatCurrency incompatible between 7.4.29 and 7.4.28

[sogaoh]

The results of running the following script were different between php:7.4.29-fpm-alpine and php:7.4.28-fpm-alpine.

<?php

$fmt = new \NumberFormatter('JA_JP', \NumberFormatter::CURRENCY);
$formatString = $fmt->formatCurrency(0, 'JPY');

var_dump($formatString);

Result

• php:7.4.28-fpm-alpine (I expects)

  string(4) "￥0"

• php:7.4.29-fpm-alpine

  string(3) "¥0"

(My) problem

Is there any way to get the results in php:7.4.29-fpm-alpine to be what they were in php:7.4.28-fpm-alpine ? (Is there a workaround?)

Way to reproduce

see https://github.com/sogaoh/reproduce-incompatibility-of-format-currency (README.md)

Remarks

( unconfirmed ) I'm guessing that there is a similar problem between

• 8.0.19 and 8.0.18
• 8.1.6 and 8.1.5

I don't see anything in https://www.php.net/manual/en/changelog.strings.php or https://www.php.net/ChangeLog-7.php

You could try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum

Isn't this change in results strange?

On the other hand,
https://stackoverflow.com/questions/31404351/comparing-phps-numberformatterformatcurrency-results
is a nice work-around tip!
Thanks for the information.

I've examined.

• php:8.0.19-fpm-alpine and php:8.0.18-fpm-alpine is same.

  • see https://github.com/sogaoh/reproduce-incompatibility-of-format-currency/tree/v80

• php:8.1.6-fpm-alpine and php:8.1.5-fpm-alpine is same, too.

  • see https://github.com/sogaoh/reproduce-incompatibility-of-format-currency/tree/v81

php:7.4.29-fpm-alpine3.15 seems to work fine, so it is likely the bump to the icu* packages in Alpine and so not anything that we could change in the images to address it.

$ docker run -it --rm php:7.4.29-cli-alpine3.15 sh
...[ installing intl ]
/ # php -a
Interactive shell

php > $fmt = new \NumberFormatter('JA_JP', \NumberFormatter::CURRENCY);
php > $formatString = $fmt->formatCurrency(0, 'JPY');
php > var_dump($formatString);
string(4) "￥0"

I've got the same result by:
https://github.com/sogaoh/reproduce-incompatibility-of-format-currency/pull/2/files

• add icu-data-full
  • refs https://alpinelinux.org/posts/Alpine-3.16.0-released.html

  The ICU data has been split into icu-data-en (default) and icu-data-full packages. 
  Users may need to install icu-data-full for non-English locales or legacy charset converters support.
