我通过论坛搜索,但无法得到权威的答案.我想以这样的方式实现嵌套的注释结构：
<ul>
<li>This is the parent first comment!
<ul>
<li>This is the reply for the first parent comment!
<ul>
<li>This is a reply for the first reply of the parent comment!</li>
<li>This is a third reply for the first parent comment!</li>
</ul>
</li>
<li>This is another reply for first parent comment!</li>
</ul>
</li>
<li>This is gonna be parent second comment!
<ul>
<li>This is a reply for the second comment!</li>
</ul>
</li>
<li>This is fourth parent comment!</li>
</ul>
我桌子的转储如下：
+----+------------------------------------------------------------+--------+ | id | text | parent | +----+------------------------------------------------------------+--------+ | 1 | This is the parent first comment! | 0 | | 2 | This is gonna be parent second comment! | 0 | | 3 | This is the reply for the first parent comment! | 1 | | 4 | This is another reply for first parent comment! | 1 | | 5 | This is a reply for the first reply of the parent comment! | 3 | | 6 | This is a reply for the second comment! | 2 | | 7 | This is a third reply for the first parent comment! | 3 | | 8 | This is fourth parent comment! | 0 | +----+------------------------------------------------------------+--------+
我为我的博客做了类似的事情.然而,我只是尝试了相同的数据.当你说嵌套注释时,你可以用这种方式使用嵌套函数：
function getComments($parent)
{
# Get the data from sql.
# Check if it has nested comments.
if (hasComments())
getComments($child); # $child is the ID of the current comment.
}
为了实现这一点,我已将您的数据导入MysqL并尝试了以下方法：
<?PHP MysqL_connect('localhost','root'); MysqL_select_db('nestedcomments'); function getComments($parent) { $res = MysqL_query("SELECT * FROM `nestcomm` WHERE `parent` = $parent"); if (MysqL_num_rows($res)) { echo "<ul>\n"; while (($dat = MysqL_fetch_array($res)) !== false) echo "<li>",$dat["text"],getComments($dat["id"]),"</li>\n"; echo "</ul>\n"; } else echo ($parent === 0) ? 'No Comments!' : ""; } getComments(0); ?>
正如我之前所说的,我已经使用了嵌套函数,并且正如您所说的那样输出几乎相同(没有大括号)：
<ul> <li>This is the parent first comment!<ul> <li>This is the reply for the first parent comment!<ul> <li>This is a reply for the first reply of the parent comment!</li> <li>This is a third reply for the first parent comment!</li> </ul> </li> <li>This is another reply for first parent comment!</li> </ul> </li> <li>This is gonna be parent second comment!<ul> <li>This is a reply for the second comment!</li> </ul> </li> <li>This is fourth parent comment!</li> </ul>
希望这会有所帮助.
