2價格（PHP）缺少小數

Question

我有2位小數的一個問題，我想這是35.99美元，而不是美元3599.

時，我不停地刷新我的網頁用於測試目的發生此問題。有時價格沒有顯示小數位，但在繼續測試我的頁面後恢復正常。

有誰知道這是爲什麼？
下面是我的PHP代碼：

// 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; 
}

localeconv（）之前，你必須使用 '的setlocale'：

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

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

或者，也許，檢查這個代碼： 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 
?> 

享受你的代碼！

編輯： 我在Windows系統中打印localconv（）數組返回，它是無效的。 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"; 
} 
?> 

所以我已閱讀本： http://php.net/manual/it/function.setlocale.php

，我必須改變參數localeconv（）：

$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); 

惠特這些作品！

在* nix系統嘗試使用此：

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