用逗号添加数字字符串

我有一个循环，它会添加我的数据库的结果。值是这种格式的数字字符串：$$$，$$$。$$我无法将结果添加到相同的格式并显示：

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."!";
};

使用上面的内容，我得到了价值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, '.', ',');

但后来我得到了$ 10,000.00的价值！

按要求输出：

numeric total: 661,379 Original total: 661379.32

3 个答案:

答案 0 :(得分：2)

输出什么？听起来你的数字可能太大而不适合31位，但在我看到你的确切输出之前很难知道。

您确定所有$row['meta_value']值都是带逗号的直号吗？试着这样做：

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";

我想知道某些值是否与预期不符。

答案 1 :(得分：0)

您也可以将值转换为浮点数：

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

修改

完整代码：

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!";
};

答案 2 :(得分：0)

您还可以从查询本身正确地格式化它们，并在您想要的字段上操作：

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