ubb解析出什么问题了，请帮忙！

[yxflove]

昨天，我用了一下www.phpe.net中一个ubb。。可是出现了这样的错误。

ubb来源：http://www.phpe.net/?n=Source&file=inc/function.inc.php

function ubbParse($txt, $coverhtml=0) {

if ($coverhtml == 0) $txt = nl2br(htmlspecialchars($txt)); //BR和HTML转换
//只转换BR，不转换HTML
if ($coverhtml == 1) {
if (!preg_match('/^<.+>$/s', $txt) && !preg_match('/<table.+<\/table>/is', $txt)) {
$txt = strip_tags($txt);
$txt = nl2br($txt);
}
}

// pre and quote
$txt = preg_replace( "#\[quote\](.+?)\[/quote\]#is", "<blockquote>\1</blockquote>", $txt );
$txt = preg_replace( "#\[code\](.+?)\[/code\]#is", "<p class='php'>\1</p>", $txt );

// Colors 支持篏套
while( preg_match( "#\[color=([^\]]+)\](.+?)\[/color\]#is", $txt ) ) {
$txt = preg_replace( "#\[color=([^\]]+)\](.+?)\[/color\]#is", "<span style='color:\1'>\2</span>", $txt );
}

// Align
$txt = preg_replace( "#\[center\](.+?)\[/center\]#is", "<center>\1</center>", $txt );
$txt = preg_replace( "#\[left\](.+?)\[/left\]#is", "<div align=left>\1</div>", $txt );
$txt = preg_replace( "#\[right\](.+?)\[/right\]#is", "<div align=right>\1</div>", $txt );

// Sub & sup
$txt = preg_replace( "#\[sup\](.+?)\[/sup\]#is", "^\1", $txt );
$txt = preg_replace( "#\[sub\](.+?)\[/sub\]#is", "_\1", $txt );

// email tags
// [e-mail] Email me
$txt = preg_replace( "#\[email\](\S+?)\[/email\]#i" , "<a href='mailto:\1'>\1</a>", $txt );
$txt = preg_replace( "#\[email\s*=\s*\"\;([\.\w\-]+\@[\.\w\-]+\.[\.\w\-]+)\s*\"\;\s*\](.*?)\[\/email\]#i" , "<a href='mailto:\1'>\2</a>", $txt );
$txt = preg_replace( "#\[email\s*=\s*([\.\w\-]+\@[\.\w\-]+\.[\w\-]+)\s*\](.*?)\[\/email\]#i" , "<a href='mailto:\1'>\2</a>", $txt );

// url tags
// http://www.phpe.net Exceed PHP!
$txt = preg_replace( "#\[url\](\S+?)\[/url\]#i" , "<a href='\1' target='_blank'>\1</a>", $txt );
$txt = preg_replace( "#\[url\s*=\s*\"\;\s*(\S+?)\s*\"\;\s*\](.*?)\[\/url\]#i" , "<a href='\1' target='_blank'>\2</a>", $txt );
$txt = preg_replace( "#\[url\s*=\s*(\S+?)\s*\](.*?)\[\/url\]#i" , "<a href='\1' target='_blank'>\2</a>", $txt );

// Start off with the easy stuff
$txt = preg_replace( "#\[b\](.+?)\[/b\]#is", "<b>\1</b>", $txt );
$txt = preg_replace( "#\[i\](.+?)\[/i\]#is", "<i>\1</i>", $txt );
$txt = preg_replace( "#\[u\](.+?)\[/u\]#is", "<u>\1</u>", $txt );
$txt = preg_replace( "#\[s\](.+?)\[/s\]#is", "<s>\1</s>", $txt );

// Images
$txt = preg_replace( "#\[img\](.+?)\[/img\]#i", "<a href='\1' target='_blank'><img alt='Click to fullsize' src='\1' border='0' onload='javascript:if(this.width>500) this.width=500' align='center' hspace='10' vspace='10'></a><br />", $txt );

// Attach
$txt = preg_replace( "#\[attach\s*=\s*\"\;\s*(\S+?)\s*\"\;\s*\](.*?)\[\/attach\]#i" , "<a href='\2' target='_blank'><b>相关附件：</b>\1</a>", $txt );
$txt = preg_replace( "#\[attach\s*=\s*(\S+?)\s*\](.*?)\[\/attach\]#i" , "<a href='\2' target='_blank'><b>相关附件：</b>\1</a>", $txt );

// Iframe
$txt = preg_replace( "#\[iframe\](.+?)\[/iframe\]#i", "<div align='center'><iframe src='\1' style='width:96%;height:400px'></iframe><br clear='all'><a href='\1' target='_blank'>在新窗口打开链接</a></div>", $txt );

// (c) (r) and (tm)
$txt = preg_replace( "#\(c\)#i" , "©" , $txt );
$txt = preg_replace( "#\(tm\)#i" , "™" , $txt );
$txt = preg_replace( "#\(r\)#i" , "®" , $txt );

return $txt;
}



下面是参考：http://www.phpe.net/?n=Source&file=article_show.php





$SQL = 'SELECT * FROM article WHERE article_id='.$a_num;
$db->query($SQL) or die('Query Error!');
if($db->num_rows()==0) { header("location:/");}
$db->next_obj();
　　$article_title = myoutput($records->article_title);
$article_from = $records->article_from;
$article_author = $records->article_author;
$article_date = $records->article_date;

//文章格式处理
if (preg_match('/\[code\].+\[\/code\]/i', $records->article_content) || !preg_match('/<\s*(p|br)\s*>/is', $records->article_content))
$records->article_content = ubbParse($records->article_content);
　
echo $records->article_content;


得到了这样的不知所以的东西：

　　











不用格式化如：<b> </b> <color> </color>的时候显示为正常的。。

在线等你帮忙啦！！

<span style='color:'></span><br />
