NumberFormatter currency format mismatch on Windows and Linux

[hanishsingla]

Description

NumberFormatter currency format produces different results on Windows and Linux machines

$ php -a
Interactive mode enabled
php > $f = new NumberFormatter('nl_NL', NumberFormatter::CURRENCY);
php > echo $f->formatCurrency('1234.5672', 'EUR')."\n";

php > $f = new NumberFormatter('fr_FR', NumberFormatter::CURRENCY);
php > echo $f->formatCurrency('1234.5672', 'EUR')."\n";

It resulted in this output:

Linux: €1,234.57
Windows: € 1.234,57

Linux: €1,234.57
Windows: 1 234,57 €

Here is 3v4l version to reproduce the error (I am not sure which server it is, but it produces results similar to Windows system) https://3v4l.org/ivbEs#v8.0.21

PHP Version

PHP 8.0.21

Operating System

Alpine Linux v3.16

This is unlikely to be a PHP bug but rather a change in the underlying ICU library between versions.

What versions of the ICU library do you have on the two systems? (phpinfo will report it in the "intl" section)
Or in other words, how old is the library you have on the Linux machine?

Not sure we should be using which version, but following info I got from Linux machine (PHP 8.0.21)

ICU version	71.1
ICU Data version	71.1
ICU Unicode version	14.0

This one is from a windows machine (PHP 8.1.4)

ICU version	70.1
ICU Data version	70.1
ICU Unicode version	14.0

See #8656 (comment).

So, issue is in Alpine Linux 3.16.0, #8656 (comment)

For anyone facing the same issue, you need to add "apk add icu-data-full" in your build. More info at https://wiki.alpinelinux.org/wiki/Release_Notes_for_Alpine_3.16.0#ICU_data_split

@cmb69 Really thanks for saving the day
