note 127359 added to class.numberformatter

When using the NumberFormatter class for pretty-printing currency in PHP 7.3 and 8+, it's not clear from the documentation that you can use the empty string "" as the locale for the constructor, and that will retrieve the default locale (whatever it has been set to in your environment). formatCurrency(), by contrast, does not accept the empty string for the default currency symbol; it will display a 'generic' currency symbol instead (¤). Tested with PHP 7.4.30, 8.0.21, 8.1.8 under Ubuntu Linux and 8.1.8 under macOS Big Sur (11.6.8). I tried under other alternatives (e.g. Linux running on ARM chips, PHP 7.3.3) but sadly the NumberFormatter library does not seem to be present (or could not be found) on those systems... ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.157.133 (proxied: 2001:8a0:7116:7200:ac69:15f7:c5e9:63fe) ---- Manual Page -- https://php.net/manual/en/class.numberformatter.php Edit -- https://main.php.net/note/edit/127359 Del: integrated -- https://main.php.net/note/delete/127359/integrated Del: useless -- https://main.php.net/note/delete/127359/useless Del: bad code -- https://main.php.net/note/delete/127359/bad+code Del: spam -- https://main.php.net/note/delete/127359/spam Del: non-english -- https://main.php.net/note/delete/127359/non-english Del: in docs -- https://main.php.net/note/delete/127359/in+docs Del: other reasons-- https://main.php.net/note/delete/127359 Reject -- https://main.php.net/note/reject/127359 Search -- https://main.php.net/manage/user-notes.php
