这是一个XN的插件代码，怎么修改成HB适合用的。。。
HB的机制还没研究透。。。.
$CNTV = preg_match_all('/\[CNTV\](.*?)\[\/CNTV\]/i',$first['message_fmt'],$array);
if($CNTV){
for($i=0;$i<count($array[0]);$i++){
$a = $array[0][$i];
$b = $array[1][$i];
$c = '<div id="embed_playerid" style="text-align:center"></div><script type="text/javascript" src="http://js.player.cntv.cn/innerShare.js"></script><script type="text/javascript" src="http://js.player.cntv.cn/creator/swfobject.js"></script><script type="text/javascript">var fo = createPlayer("v_player",640,480);fo.addVariable("videoId","vid");fo.addVariable("videoCenterId","';
$d = '");fo.addVariable("videoType","0");fo.addVariable("videoEditMode","1");fo.addVariable("isAutoPlay","false");fo.addParam("wmode","opaque");writePlayer(fo,"embed_playerid");</script>';
$e = "$c$b$d";
if($user){
$first['message_fmt'] = str_replace($a,$e,$first['message_fmt']);
}else{
$first['message_fmt'] = str_replace($a,$e,$first['message_fmt']);
}
}
}
