my current code is :我目前的代码是：

<!doctype html>
<html>
<head>

<title>time stats</title>

<style>
body {
background-color: black;
}
.box1 {
width: 300px;
height: 400px;
border: 15px solid yellow;
padding: 15px;
margin: 15px;
display: inline-block;
color: white;
font-size:40px;
color: lime;

.container  {
text-align: center;
}
</style>
<body>
<div class="box1">
<?php
$q = intval($_GET['q']);

$con = mysqli_connect('localhost','username','password','test');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}

mysqli_select_db($con,"ajax_demo");
$sql="select avg(time_format(delivery_avg,'%i:%s')) as time_avg from test.del where location = 'yellow'";
$result = mysqli_query($con,$sql);

echo "<table>
<thead>
<th>time Average</th>
</thead>";
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['time_avg'] . "</td>";
echo "</tr>";}
echo "</table>";
mysqli_close($con);
?>
</div>
  function updatecolor() {
        //console.log('function called');
        {
if ($box1.td < 10)
    return '#00FF00';
else if ($box1.td >= 11 && $box1.td<= 15)
    return = '#FFA500';
else if ($box1.td >= 16 && $box1.td<= 20)
    return = '#ff0000';
}
        });

    }
    var updateInterval = setInterval(updatecolor, 1000);
</body>
</html>

Here's a little function that will return your colors depending on the $valueToCheck parameter of the function:这是一个小函数，它将根据函数的$valueToCheck参数返回您的颜色：

<?php
function addColor($valueToCheck) {
    {
        if ($valueToCheck <= 10) {
            return '#00FF00';
        } else if ($valueToCheck >= 11 && $valueToCheck <= 15) {
            return '#FFA500';
        } else if ($valueToCheck >= 16 && $valueToCheck <= 20) {
            return '#ff0000';
        }
    };
}
?>

Wrapped it in <?php ?> tags, since it's a PHP function.将它包裹在<?php ?>标签中，因为它是一个 PHP 函数。

Use it in your HTML like so:在您的 HTML 中使用它，如下所示：

while($row = mysqli_fetch_array($result)) {
  echo "<tr>";
  echo "<td style=\"color:" . addColor($row['time_avg']) . "\">";
  echo $row['time_avg'];
  echo "</td>";
  echo "</tr>";
}

As for your code:至于你的代码：

return = '#FFA500'; is not valid, remove the = .无效，删除= 。

If $box1 were available:如果$box1可用：

if ($box1.td < 10)
    return '#00FF00';
else if ($box1.td >= 11 && $box1.td<= 15)

What about 10 ? 10呢？ You never check for 10>x>11 .你从不检查10>x>11 。
