        //$Text=htmlspecialchars($Text);
        //$Text=ereg_replace("\r\n","<br>",$Text);
        $Text=ereg_replace("\[br\]","<br />",$Text);
        $Text=nl2br($Text);
        $Text=stripslashes($Text);
        $Text=preg_replace("/\\t/is"," ",$Text);
        $Text=preg_replace("/\[url\](http:\/\/.+?)\[\/url\]/is","<a href=https://www.jb51.net/article/\"\\1\" target=https://www.jb51.net/article/\"new\"><u>\\1</u></a>",$Text);
