我有一个循环，它添加了数据库中的结果。这些值是采用以下格式的数字字符串:$$$,$$$.$$ 我无法将结果相加并以相同的格式显示:
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，我得到类似“Worth $653987.32!”的结果。现在我需要重新插入逗号，所以我尝试这样做:
$value = number_format($value, 2, '.', ',');
但是我得到了 10,000.00 美元的值(value)!

最佳答案
它输出什么？听起来你的数字可能太大，无法容纳 31 位，但在我看到你的确切输出之前很难知道。
您确定所有 $row['meta_value'] 值都是带逗号的正数吗？尝试这样做:
while($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";
我想知道是否有些值不符合您的预期。
