表格內容是否在表格之外？

我正在試圖回顯一張信息表，特別是帖子。表格內容是否在表格之外？

<?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>"; 
?>

這是我結束了（HTML輸出）：在這樣的index.php文件

<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>

php文件是「include'd」：「包括 'topic.php' 「並且需要從我的數據庫中回顯出一張數據表。這是爲什麼發生？另外，這裏是我的樣式表：

這似乎並不是您發佈的php生成的html。例如，在你的php中沒有''元素。您應該發佈真實的html源代碼，而不是螢火蟲或開發人員工具向您展示的內容。那究竟是什麼問題？ – jeroen 2013-02-09 13:49:47

Woops，我無意中從Chrome的「檢查元素」中抓住了HTML，我用正確的代碼更新了帖子！ – user1768788 2013-02-09 13:53:20

的HTML看起來像一個爛攤子。

你應該做的第一件事情是要確保你生成有效的HTML：

不要放在<div>元素的<ul>直接兒童;
對輸出到html的所有變量使用htmlspecialchars以確保這些值不會破壞html。
使用>代替>等

此外，您的查詢有SQL注入漏洞。您應該使用預處理語句和綁定變量切換到PDO（或mysqli），以避免這種情況，或者至少將$_GET變量設置爲int（如果它是整數），如果它是字符串，則使用mysql_real_escape_string。
