在php中添加一个美元符号

Question

我从数据库中获取数据并将其插入此表中。  

while (($result_row = $result->fetch_assoc()) !== NULL) {
    echo "<tr>";
    echo "<td>", $result_row['title'], "</td>";
    echo "<td>", $result_row['author'], "</td>";
    echo "<td>", $result_row['isbn'], "</td>";

    echo  "<td>", $result_row['price'], "</td>";

    echo "</tr>";
}

我似乎无法弄清楚如何以价格打印实际的$。有什么建议吗？

Answer 1

    echo  "<td>\$", $result_row['price'], "</td>";

或更好，请使用money_format（）http://php.net/manual/en/function.money-format.php

Answer 2

echo  "<td>$", $result_row['price'], "</td>";
