php mysqli获取数据并划分两个变量(2) /两个小数点位置

Question

我已经能够将两个变量从mysqli查询分开...我如何将数字分为两个小数点/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>";
}

所以，bet_count/win_count按预期工作.....我只需要整数，例如2.371237234至小数点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>";
}
