NumberFormat shows incorrect results

Please answer these questions before submitting your issue.

1. What did you do? If possible, provide a simple script for reproducing the error.

$numberFormatter = new NumberFormatter('de-DE', 2);
$numberFormatter->setAttribute(7, 2);

$symbol = $numberFormatter->getSymbol(\NumberFormatter::INTL_CURRENCY_SYMBOL);
var_dump($numberFormatter->formatCurrency(12345.12345,  $symbol));

The Snipped running on laravel octane (by swoole) will return €12,345.12.

The correct value would be 12.345,12 €, as you can see here: https://onlinephp.io/c/72954

I checked the documentation, and there is no specific stuff regarding the server configuration (https://www.php.net/manual/en/intl.configuration.php).

2. What did you expect to see?
   A correctly german formatted value: 12.345,12 €

3. What did you see instead?
   A us formatted value: €70,000.00

4. What version of Swoole are you using (show your php --ri swoole)?
   5.0.2

5. What is your machine environment used (show your uname -a & php -v & gcc -v) ?
