数字格式与货币符号

Is it possible to put a currency symbol before rounding off the values ? or Alternatives maybe .

echo number_format((float)$overall_total, 2, '.', ''); //748.10

Expected output should be : $ 748.10

From tims's comment:

echo '$'.number_format

echo '$'.number_format((float)$overall_total, 2, '.', '');

$number = 1234.56;

// let's print the international format for the en_US locale
setlocale(LC_MONETARY, 'en_US');
echo money_format('%i', $number) . "
";
// USD 1,234.56

Try to use money_format()

setlocale(LC_MONETARY, 'en_US');
echo money_format('%i', $number) . "
";
