我正在尝试用信息回应一个表格，特别是帖子。
<?php
echo "
<div class='forum_banner'>
<div style='float:left;'>
<a href='?action=forum'>Forum</a>
>
<a href='?action=forum#".fetch_info(fetch_info(fetch_info($_GET['id'], 'board_id', 'topic'), 'category_id', 'board'), 'name', 'category')."'>".fetch_info(fetch_info(fetch_info($_GET['id'], 'board_id', 'topic'), 'category_id', 'board'), 'name', 'category')."</a>
>
<a href='?action=board&id=".fetch_info($_GET['id'], 'board_id', 'topic')."'>".fetch_info(fetch_info($_GET['id'], 'board_id', 'topic'), 'name', 'board')."</a>
>
<a href='?action=topic&id=".$_GET['id']."'>".fetch_info($_GET['id'], 'name', 'topic')."</a>
</div>";
if (isset($_SESSION['id']))
{
echo "
<div style='float:right;'>
<form method='post' action='?action=create&type=reply&id=".$_GET['id']."'>
<input type='submit' value='Reply'/>
</form>
</div>";
}
echo "
</div>";
echo "
<div class='content'>
<table class='forum_table'>";
$query = mysql_query("SELECT * FROM post WHERE topic_id='".$_GET['id']."' ORDER BY time ASC") or die(mysql_error());
echo "
<tr>
<td class='table_header' colspan='2'>
<b>".fetch_info($_GET['id'], 'name', 'topic')."</b>
</td>
</tr>";
while($query_fetch = mysql_fetch_assoc($query))
{
echo "
<tr>
<td class='forum_table_cell_post' width='25%'>
<ul class='post_info'>
<li><b><a href='?action=user&id=".$query_fetch['creator']."'>".fetch_info($query_fetch['creator'], 'name', 'user')."</a></b></li>
<li>".fetch_info($query_fetch['creator'], 'rank', 'user')."</li>
<li style='max-width:128px; max-height:128px; overflow:hidden;'><img src='".fetch_info($query_fetch['creator'], 'avatar', 'user')."' /></li>
<li>Posts: ".count_post($query_fetch['creator'])."</li>
<li>Reputation: ".(fetch_info($query_fetch['creator'], 'reputation', 'user')>0 ? ('<font color="#007D00">+'.fetch_info($query_fetch['creator'], 'reputation', 'user').'</font>') : (fetch_info($query_fetch['creator'], 'reputation', 'user')<0 ? ('<font color="#7D0000">'.fetch_info($query_fetch['creator'], 'reputation', 'user').'</font>') : ('<font color="#000000">'.fetch_info($query_fetch['creator'], 'reputation', 'user').'</font>')))."</li>
</ul>
</td>
<td class='forum_table_cell_post' width='75%'>
<ul class='post_info'>
<li><i>".convert_date($query_fetch['time']) + ($query_fetch['edit']=='0000-00-00 00:00:00' ? '' : (', last edit: '.convert_date($query_fetch['edit'])))."</i></li>
<div class='spacer'></div>
<li>".$query_fetch['body']."</li>
".(fetch_info($query_fetch['creator'], 'signature', 'user') ? '<div class=\'spacer\'></div>' : '')."
<li>".fetch_info($query_fetch['creator'], 'signature', 'user')."</li>
</ul>
</td>
</tr>
";
}
echo "
</table>
</div>";
?>
这就是我最终的结果（HTML输出）：
<div class='forum_banner'>
<div style='float:left;'>
<a href='?action=forum'>Forum</a>
>
<a href='?action=forum#General'>General</a>
>
<a href='?action=board&id=1'>General discussion</a>
>
<a href='?action=topic&id=1'>First topic</a>
</div>
<div style='float:right;'>
<form method='post' action='?action=create&type=reply&id=1'>
<input type='submit' value='Reply'/>
</form>
</div>
</div>
<div class='content'>
<table class='forum_table'>
<tr>
<td class='table_header' colspan='2'>
<b>First topic</b>
</td>
</tr>0</i></li>
<div class='spacer'></div>
<li>Nice first post!</li>
<div class='spacer'></div>
<li>"Non incautus futuri"</li>
</ul>
</td>
</tr>
0</i></li>
<div class='spacer'></div>
<li>This is the first topic ever made! This is the first topic ever made! This is the first topic ever made!</li>
<div class='spacer'></div>
<li>"Non incautus futuri"</li>
</ul>
</td>
</tr>
</table>
</div>
这个php文件在index.php中是“include'd”，如下所示：“include'topic.php'”，它可以回显出我数据库中的数据表。为什么会这样？ 另外，这是我的样式表：

html看起来很混乱。
您应该做的第一件事是确保生成有效的html：
<div>元素作为<ul>; htmlspecialchars，以确保这些值不会破坏html。>代替>等此外，您的查询有一个SQL注入漏洞。您应该使用预准备语句和绑定变量切换到PDO（或mysqli）以避免这种情况，或者至少将$_GET变量转换为int如果它是整数/使用mysql_real_escape_string它是一个字符串。
