用PHP和ACCESS写聊天室(九)

enterrm.php3
代码如下:
<?php
        $ConnID=@odbc_connect("jtfcht","admin","");
        if ($ConnID){
                $result=@odbc_exec($ConnID,"SELECT PassWord,LstTime,RoomID,RefRate FROM User WHERE UserID=".$id);
                if (@odbc_fetch_into($result,0,&$rArr)){
                        $sRoomID=$rArr[2];
                        $sRefRate=(int)$rArr[3];
                        if ($sRefRate<2) $sRefRate=2;
                        if (($rArr[0]==$ps) && ($rArr[1]>=(time()-1800))){
                                $sNewRoomID=substr($selRoom,2);
                                if ($sNewRoomID!=$sRoomID){
                                        $result=@odbc_exec($ConnID,"SELECT Password FROM Room WHERE RoomID=".$sNewRoomID);
                                        if (@odbc_fetch_into($result,0,&$rArr)){
                                                if ((strlen(trim($rArr[0]))==0) || ($rArr[0]==$sPass)){
                                                        @odbc_exec($ConnID,"UPDATE User SET RoomID=".$sNewRoomID.",ToID=0,ToName='大家' WHERE UserID=".$id);
                                                        if ((int)$sRoomID!=1){
                                                                $result=@odbc_exec($ConnID,"SELECT COUNT(UserID) FROM User WHERE RoomID=".$sRoomID);
                                                                @odbc_fetch_into($result,0,&$rArr);
                                                                if ($rArr[0]==0) @odbc_exec($ConnID,"DELETE * FROM Room Where RoomID=".$sRoomID);
                                                        }
                                                }
                                                else{
