php mysqli获取数据并将两个变量除以Fixed（2）/两个小数位

Question

我已经能够从mysqli查询中除以两个变量...如何将数字除以两个小数位/ toFIxed（2）

php

$Date = $_GET['date'];
    $Win = 'Win';

$testsql="
SELECT 
count(*) AS bet_count,
SUM(IF(result ='$Win', 1, 0)) AS win_count
FROM bets WHERE betDate = '$Date' GROUP BY betDate 
";

$testresult = mysqli_query($connection, $testsql);

while ($testrow = mysqli_fetch_assoc($testresult))
{ 
    echo "<tr>";
echo "<td class='text-center'>".($testrow['bet_count']/$testrow['win_count']). "</td>";
echo "</tr>";
}

因此，bet_count / win_count可以正常工作.....我只需要整数例如2.371237234保留两位小数2.37

您可以尝试使用number_format()函数：

<?php
$Date = $_GET['date'];
$Win = 'Win';

$testsql = "
   SELECT 
      count(*) AS bet_count,
      SUM(IF(result ='$Win', 1, 0)) AS win_count
   FROM bets WHERE betDate = '$Date' GROUP BY betDate 
";

$testresult = mysqli_query($connection, $testsql);

while ($testrow = mysqli_fetch_assoc($testresult)) { 
    echo "<tr>";
    $value = number_format($testrow['bet_count']/$testrow['win_count'], 2, '.', '');
    echo "<td class='text-center'>".$value."</td>";
    echo "</tr>";
}
