在 PHP 中将公式答案设置为两个小数

Question

$query=mysql_query($sql,$connect);
while($row = mysql_fetch_array($result3)){
    echo "Total Profit = RM ". $row['SUM(profit)'];
    echo "<br />";
}
echo"</br>";
echo "<b><u>Total Profit earned </u></b>" ;
echo"</br>";
$query1 = "SELECT country, SUM(profit) FROM `table 1` GROUP BY country"; 
$result1 = mysql_query($query1) or die(mysql_error());
while($row = mysql_fetch_array($result1)){
    echo "". $row['country']. " = RM ". $row['SUM(profit)'];
    echo "<br />";
}

我的代码有效，但我需要将利润设置为小数点后 2 位。而不是RM 373037194.867713152，我希望它显示为RM 373037194.87。

Answer 1

使用 round(( 轻松

echo "". $row['country']. " = RM ". round($row['SUM(profit)'], 2);

Answer 2

使用round()

round($row['SUM(profit)'], 2); // round to two decimal places
