Get currency symbol in PHP

Question

Let\'s start with simple piece of code to format money with NumberFormatter:

$formatter = new NumberFormatter(\'en_US\', NumberFormatter::CURREN         


        

Answer 1

Since the symbols can be multi-byte I used mb_*() functions to correctly grab the all non-punctuation and non-digit chars which would just leaves the symbol.

function get_currency_symbol($string)
{
    $symbol = '';
    $length = mb_strlen($string, 'utf-8');
    for ($i = 0; $i < $length; $i++)
    {
        $char = mb_substr($string, $i, 1, 'utf-8');
        if (!ctype_digit($char) && !ctype_punct($char))
            $symbol .= $char;
    }
    return $symbol;
}

$format = new NumberFormatter('en_US', NumberFormatter::CURRENCY);
$string = $format->formatCurrency(123456789, 'JPY');
echo get_currency_symbol($string);

Answer 2

Try this variant:

$formatter->getSymbol(NumberFormatter::INTL_CURRENCY_SYMBOL);
