Bug #80611 [Opn->Fbk]: NumberFormatter appears to have broken in PHP 8.x.

Edit report at https://bugs.php.net/bug.php?id=80611&edit=1 ID: 80611 Updated by: cmb@php.net Reported by: kit dot soul at usweek dot net Summary: NumberFormatter appears to have broken in PHP 8.x. -Status: Open +Status: Feedback Type: Bug Package: Output Control Operating System: Windows PHP Version: 8.0.1 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: Have you considered to report that upstream[1]? [1] <http://site.icu-project.org/bugs> Previous Comments: ------------------------------------------------------------------------ [2021-01-11 18:44:45] cmb@php.net That is apparently an upstream issue; when building PHP 8.0 with ICU 66.1 everything works as expected, but with ICU 67.1 the issue is reproducible. It is not particularly related to BTC (that currency is only supported as of ICU 68.1), but also reproduces with EUR, for instance. It is also not related to an empty string as currency symbol, but shows with '$' as well. ------------------------------------------------------------------------ [2021-01-09 21:49:06] kit dot soul at usweek dot net Description: ------------ NumberFormatter's formatCurrency() function no longer respects an empty currency symbol. Output of test script in PHP 7.4.13 (Windows): string(6) "0.0043" Output of test script in PHP 8.0.1 (Windows): string(11) "BTC 0.0043" Conclusion: Something has changed. I cannot find any mention whatsoever of PHP 8 here: https://www.php.net/manual/en/numberformatter.formatcurrency.php I asked it here but nobody can even reproduce it (possibly because they don't use Windows?): https://stackoverflow.com/questions/65636460/how-to-resolve-this-new-bug-change-in-behaviour-in-php-8-x-in-regards-to-numberf Test script: --------------- $a = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY); $a->setAttribute(\NumberFormatter::MAX_FRACTION_DIGITS, 8); $a->setSymbol(NumberFormatter::CURRENCY_SYMBOL, ''); // It's empty because I want it "minimal" for a table cell. var_dump($a->formatCurrency(0.0043, 'BTC')); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80611&edit=1
