The following code out puts a figure for shipping cost based on a currency conversion that happens elsehwere, but it outputs with many decimal places. Can I alter something here that will produce a number with just 2 decimal places?
下面的代码输出了一个基于其他地方发生的货币转换的运费数字，但它输出了许多小数位。我可以在这里更改一些会产生只有 2 个小数位的数字吗？
if(isset($_POST['ShippingMethod'])){
$order['data'] .= "\r\n ========== Shipping Cost ========== \r\n\r";
$order['data'] .="\r\n Shipping Method Cost: ". $_SESSION['currency_symbol'].$_POST['ShippingMethod']. " \r\n";
$form['price']['shipping'] +=$_POST['ShippingMethod'];
}

看看http://php.net/number_format，如果它与货币有关，请查看http://php.net/manual/en/function.money-format.php
