我正在尝试在我的表格中包含一行突出显示。进入表格的我的数据设置如下。我有一个输入数据的html页面。从那个页面，我有一个单独的php文件，它将这些结果写入文本文件。然后我有另一个php文件，它从文本文件中读取数据并将数据放入表中。然后对该数据进行分类，因为输入的数据将在不同的时间输入。由于数据是动态排序的，我的问题是，如何突出显示该表的第一行？在我的情况下，第一行将有最快的时间。
这是我的html页面。
<html>
<form method = "POST" action = "TimeSubmitFinal.php" target = "TimeSubmitFinal.php">
<table>
<tr>
<td><h3> Group 1 </h3></td>

<tr>

这是我的第一个php页面
<?php
//make sure text file is in directory
$txt1 = file("data1.txt");
//Group1 POSTS
$ash = 'ASH';
$ashrun = $_POST['ash_run'];
$ashpen = $_POST['ash_pen'];
$ashcom = $_POST['ash_com'];
$atl = 'ATL';
$atlrun = $_POST['atl_run'];
$atlpen = $_POST['atl_pen'];
$atlcom = $_POST['atl_com'];
$col = 'COL';
$colrun = $_POST['col_run'];
$colpen = $_POST['col_pen'];
$colcom = $_POST['col_com'];
$sav = 'SAV';
$savrun = $_POST['sav_run'];
$savpen = $_POST['sav_pen'];
$savcom = $_POST['sav_com'];
$result1 = '';
foreach($txt1 as $line1)
{
if(substr($line1,0,3) == 'ASH')
{
$result1 .= $ash. ' '. $ashrun. ' '. $ashpen. ' '. $ashcom. "\r\n".
$atl. ' '. $atlrun. ' '. $atlpen. ' '. $atlcom. "\r\n".
$col. ' '. $colrun. ' '. $colpen. ' '. $colcom. "\r\n".
$sav. ' '. $savrun. ' '. $savpen. ' '. $savcom. "\r\n";
}
}
file_put_contents("data1.txt", $result1);
?>
这是我显示数据的php
<html>
<head>
<?php
$lines = file("data.txt", FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
$data = array_map(function($v){

usort($data, function($a, $b){
if($a["comtime"] == $b["comtime"])
return 0;
return $a["comtime"] > $b["comtime"] ? 1 : -1;
});

将以下代码添加到CSS文件中：
.tablesorter tbody tr:first-child td {
background-color: #FFFF66;
}
将颜色代码更改为您喜欢的颜色。
答案 1 :(得分：1)
设置一个字符串，在循环之前应用高亮类，然后在循环中将其设置为空字符串。
$class = ' class="highlight"';
foreach($data1 as $site1) { ?>
<tr<?php echo $class; //highlight is applied the first time ?>>
<td> <b><?php echo $site1["site"]; ?> </td>
<td> <b><?php echo $site1["runtime"];?> </td>
<td> <b><?php echo $site1["pentime"]; ?> </td>
<td> <b><?php echo $site1["comtime"]; ?> </td>
</tr>
<?php
$class = ''; // highlight will not be applied in subsequent iterations
} ?>
答案 2 :(得分：0)
这应该有效：
<?php $highlight=TRUE; foreach($data1 as $site1) { ?>
<tr <?php echo ($highlight ? 'class="highlight"' : ''); $highlight=false; ?>>
<td> <b><?php echo $site1["site"]; ?> </td>
<td> <b><?php echo $site1["runtime"];?> </td>
<td> <b><?php echo $site1["pentime"]; ?> </td>
<td> <b><?php echo $site1["comtime"]; ?> </td>
</tr>
<?php } ?>
