Question

花了几个小时试图解决这个问题，但没有成功，只是不是一个好的程序员。我有2个标题称为标题和日期，我试图阻止它们在每一行之前重复。我只想把标题放在顶部。我需要做些什么才能实现这一目标。谢谢！！！！使用比特币进行搜索。

<thead>
        <tr>
          <th class='table-header' width='20%'>Title</th>
          <th class='table-header' width='5%'>Date</th>
        </tr>
      </thead>

Answer 1

这样就可以了：

要测试的数组（在你的情况下使用$ result）

$result=array(
array('post_title'=>'title 1','post_at'=>'at 1'),
array('post_title'=>'title 2','post_at'=>'at 2'),
array('post_title'=>'title 3','post_at'=>'at 3'),
)

HTML：

<table class='tbl-qa'>
<tr>
    <th class='table-header' width='20%'>Title</th>
    <th class='table-header' width='5%'>Date</th>
</tr>
<?php
    if(!empty($result)) { 
        foreach($result as $row) {
        ?>
        <tr class='table-row'>
            <td><a style="text-decoration: none;" href="<?php echo $row['description']; ?>">
            <?php echo $row['post_title']; ?></a></td>
            <td><?php echo $row['post_at']; ?></td>
        </tr>
        <?php
        }
    ?>
    <?php
    }
?>

正如您所看到的，标题只写了一次，因为它不在循环中，而循环内的行将重复。最后将表格从循环中关闭。
