PHP NumberFormatter parseCurrency returning false

Question

I'm trying this:

 public static function money($str)
    {
        $currency = 'BRL';
        $formatter = new \NumberFormatter('pt_BR', \NumberFormatter::CURRENCY);

        return $formatter->parseCurrency($str, $currency);
    }

I'm trying to parse a string like "R$ 123,45" to "123.45", but it returns false everytime.

According to ISO 4217 BRL is the CODE for Brazil currency: https://en.wikipedia.org/wiki/ISO_4217

What am i doing wrong?

Answer 1

This should work

 public function currency($str, $currency = 'BRL')
 {
     // use of NumberFormatter from extension //

     $formatter = new \NumberFormatter('pt_BR', \NumberFormatter::CURRENCY);
     return $formatter->formatCurrency($str, $currency);
 }
