Cannot use positional argument after named argument

class getFormattedNumber
{
    public $value;
    public $locale;
    public $style = NumberFormatter::DECIMAL;
    public $precision = 2;
    public $groupingUsed = true;
    public $currencyCode = 'USD';

    function set($value, $locale, $style, $precision, $groupingUsed, $currencyCode)
    {
        $this->value = $value;
        $this->locale = $locale;
        $this->style = $style;
        $this->precision = $precision;
        $this->groupingUsed = $groupingUsed;
        $this->currencyCode = $currencyCode;
    }

    function get()
    {
        $formatter = new get($locale, $style);
        $formatter->setAttribute(attribute: NumberFormatter::FRACTION_DIGITS, $precision);
        $formatter->setAttribute(attribute: NumberFormatter::GROUPING_USED, $groupingUsed);
        if ($style == NumberFormatter::CURRENCY) {
            $formatter->setTextAttribute(attribute: NumberFormatter::CURRENCY_CODE, $currencyCode);

        }

        return $formatter->format($value);
    }
}

$a = new getFormattedNumber();
$a->set(value: 12345678.9);
echo $a->get();
