php echo'd表中的超链接问题
我的代码有问题，希望有人能帮忙 我尝试使用php echo调用信息，以表格形式显示信息，除了无法识别$id的链接外，它也可以工作。如果我不将其放入表格形式，它可以工作，但在美学上并不吸引人 如有任何建议，将不胜感激php echo'd表中的超链接问题,php,hyperlink,echo,Php,Hyperlink,Echo,我的代码有问题，希望有人能帮忙 我尝试使用php echo调用信息，以表格形式显示信息，除了无法识别$id的链接外，它也可以工作。如果我不将其放入表格形式，它可以工作，但在美学上并不吸引人 如有任何建议，将不胜感激 <?php session_start(); if(!isset($_SESSION['name'])){ header("location: ../index.php"); exit(); } // Script Error Reporting error_repor

在打印变量时，主字符串必须用双引号括起来。如果要在PHP中插入变量，需要使用双引号。echo“$id”将直接打印$id，而echo$id将打印变量的值。不过，我建议采取另一种办法。不要在不需要的地方使用PHP。没有必要如此频繁地使用echo 我会将循环的内容更改为：
?>
<tr>
<td><?=$row['msg_name']?></td>
<td><?=$row['msg_email']?></td>
<td><?=$row['msg_subject']?></td>
<td><?=$row['msg_date']?></td>
<td><a href="mailto:<?=$row['msg_email']?>">Reply</a></td>
<td><a href="admin_messages.php?deleteid=<?=$id?>">Delete</a></td>
</tr>
<?php
?>
<tr>
<td><?=$row['msg_name']?></td>
<td><?=$row['msg_email']?></td>
<td><?=$row['msg_subject']?></td>
<td><?=$row['msg_date']?></td>
<td><a href="mailto:<?=$row['msg_email']?>">Reply</a></td>
<td><a href="admin_messages.php?deleteid=<?=$id?>">Delete</a></td>
