使用逗号加上数字串

我有一个循环来添加我的数据库中的结果。这些值都是这种格式数字字符串：$$$，$$$ $$我遇到了麻烦，结果加起来，并显示在相同的格式：使用逗号加上数字串

function totals(){ 
    $result = mysql_query("SELECT meta_value FROM postmeta WHERE postmeta.meta_key = 'Value'"); 
    $value = 0; 
    while($row = mysql_fetch_array($result)) { 
     $value = $value + str_replace(',', '', $row['meta_value']); 
    } 
    echo "Worth $".$value."!"; 
};

使用上面，我得到的东西价值653987.32美元！现在我需要重新插入逗号，所以我试试这个：

$value = number_format($value, 2, '.', ',');

但是后来我得到了价值$ 10,000.00！根据要求

输出：

听起来就像在数据库的VARCHAR字段中存储数字一样。你真的应该改变字段为数字，并使用数据库的聚合函数来为你做你的计算。我看不到将数字存储为字符串的逻辑。 – 2012-04-26 01:09:57

我不行。数字正在通过wordpress插入 - 一切都是字符串。 – Sweepster 2012-04-26 01:12:04

它输出什么？这听起来像你的数字可能太大，不适合31位，但很难知道，直到我看到你的确切输出。

您确定您所有的$row['meta_value']值都是带逗号的直线数字吗？尝试这样做：

while($row = mysql_fetch_array($result)) { 
    echo "Value: {$row['meta_value']}\n"; 
    $value += str_replace(',', '', $row['meta_value']); 
} 

echo "final value: $value\n"; 
echo "formatted: ".number_format($value, 2)."\n";

我不知道是否有些值不像您预期​​的那样。

您可以将第一行两行添加到脚本的末尾 - 在尝试格式化之前，$值是多少？ – Cal 2012-04-26 00:59:39

哦！你*在*循环之后放置了'number_format（）'行*，对吗？ – Cal 2012-04-26 01:00:42

输出已过帐。 – Sweepster 2012-04-26 01:06:51

您也可以施放价值为浮点数：

(float)str_replace(',','',$row['meta_value'])

编辑：

全码：

function totals() { 
    $result = mysql_query("SELECT meta_value FROM postmeta WHERE postmeta.meta_key = 'Value'"); 
    $value = 0; 
    while ($row = mysql_fetch_array($result)) { 
     $value += (float)str_replace(',', '', $row['meta_value']); 
    } 
    echo "Worth \$$value!"; 
};

你也可以让他们正确地从查询格式本身，并在你想要的领域进行操作：

SELECT replace(meta_value, ',', '') as number_value, meta_value as original_value 
FROM postmeta 
WHERE postmeta.meta_key = 'Value'
