最近挖了个坑把自己埋得差不多了，唉，说点什么好呢？太lower么
新功能需要还原贴内信息，同步到其他系统。网上看了下并没有相关内容，并且有不少遇到了parseattach还原问题。这里发下我解决的代码：
关于贴内附件还原discuz原始方法：
$tid=181281;
$pid=4645197;
$aid=190137;
$pids = array (
$pid
);
$attachs = array (
$pid => array (
$aid
)
);
$list = array (
$pid => array (
'message' => '嘀嗒嘀嗒嘀嗒嘀嗒嘀嗒嘀嗒的 的的的 的 <br />[attach]190137[/attach]<br />',
'pid' => $pid,
'attachments' => array ()
)
);
require_once libfile ( 'function/attachment' );
$_G ['tid'] = $tid;
parseattach ( $pids, $attachs, $list );
var_dump($list);
改良过得帖子内容还原
