Question

我有2个小数位的问题，我希望它是35.99美元而不是3599美元。

当我为了测试目的而不断刷新页面时，会出现此问题。有时价格显示没有小数位，但在我继续测试我的页面后恢复正常。

有谁知道为什么会这样？
下面是我的PHP代码：

// format for currency values
function cartweaverMoney($theNum) {
    $cwLocaleInfo = localeconv();
    $cwLocaleInfo["currency_symbol"] = 'USD ';
    $retStr = number_format($theNum, 
                    2, 
                    $cwLocaleInfo["mon_decimal_point"],
                    $cwLocaleInfo["mon_thousands_sep"]);
    if ($cwLocaleInfo["p_cs_precedes"]) {
        if ($cwLocaleInfo["p_sep_by_space"]) {
            $retStr = " ".$retStr;
        }
        $retStr = $cwLocaleInfo["currency_symbol"].$retStr;
    } else {
        if ($cwLocaleInfo["p_sep_by_space"]) {
            $retStr .= " ";
        }
        $retStr .= $cwLocaleInfo["currency_symbol"];
    }
    return $retStr; 
}

在localeconv（）之前，您必须使用'setlocale'：

setlocale(LC_ALL, "en_US");
$locale_info = localeconv();

http://php.net/manual/it/function.localeconv.php

或者，也许，检查此代码： http://php.net/manual/it/function.number-format.php

<?php
$var = number_format(2234,2);
$var = number_format($var,2);
echo $var;
# Expected Output: 2,234.00
# Actual Output: 2.00
?>

//To fix, remove the thousands separator by setting the decimal point and thousands separator parameters like so:

<?php
$var = number_format(2234,2,'.','');
$var = number_format($var,2,'.','');
echo $var;
# Expected Output: 2234.00
# Actual Output: 2234.00
?>

享受您的代码！

编辑：我已经在Windows系统中打印了localconv（）数组返回，它是无效的。 setloca

le(LC_ALL, "en_US");
$cwLocaleInfo = localeconv();
function print_locale_conv($locale_info) {
    echo "<pre>\n";
    echo "--------------------------------------------\n";
    echo "  Informazioni sulla configurazione monetaria locale:  \n";
    echo "--------------------------------------------\n\n";

    echo "int_curr_symbol:   {$locale_info["int_curr_symbol"]}\n";
    echo "currency_symbol:   {$locale_info["currency_symbol"]}\n";
    echo "mon_decimal_point: {$locale_info["mon_decimal_point"]}\n";
    echo "mon_thousands_sep: {$locale_info["mon_thousands_sep"]}\n";
    echo "positive_sign:     {$locale_info["positive_sign"]}\n";
    echo "negative_sign:     {$locale_info["negative_sign"]}\n";
    echo "int_frac_digits:   {$locale_info["int_frac_digits"]}\n";
    echo "frac_digits:       {$locale_info["frac_digits"]}\n";
    echo "p_cs_precedes:     {$locale_info["p_cs_precedes"]}\n";
    echo "p_sep_by_space:    {$locale_info["p_sep_by_space"]}\n";
    echo "n_cs_precedes:     {$locale_info["n_cs_precedes"]}\n";
    echo "n_sep_by_space:    {$locale_info["n_sep_by_space"]}\n";
    echo "p_sign_posn:       {$locale_info["p_sign_posn"]}\n";
    echo "n_sign_posn:       {$locale_info["n_sign_posn"]}\n";
    echo "</pre>\n";
}
?>

所以我读过这个： http://php.net/manual/it/function.setlocale.php

我已经更改了localeconv（）的参数：

$lang = "us_US";
$language = 'english';
$codeset = "UTF8";  // warning ! not UTF-8 with dash '-'

date_default_timezone_set('Europe/Rome');
setlocale(LC_ALL, array($lang.'.'.$codeset,$lang.'@euro',$lang,$language));

$cwLocaleInfo = localeconv();

print_locale_conv($cwLocaleInfo);

惠特这些作品！

对于* nix系统，请尝试使用此：

$lang = "us_US";
$language = 'english';
$codeset = "UTF8";  // warning ! not UTF-8 with dash '-'
putenv('LANG='.$lang.'.'.$codeset);
putenv('LANGUAGE='.$lang.'.'.$codeset);

价格中缺少2位小数（PHP）
