用PHP和ACCESS写聊天室(七)

chtcont.php3:

代码如下：

$sCont="";

$ConnID=@odbc_connect("jtfcht","admin","");

if ($ConnID){

if ($id=="1" && $ps="superldz"){

$result=@odbc_exec($ConnID,"SELECT TOP 25 sTime,sCont,sNameFrom,sNameTo,SeqID,sIPFrom FROM ChtCont ORDER BY SeqID DESC");

$lMax=-1;

while (@odbc_fetch_into($result,0,&$rArr)){

$sLine=$rArr[0]." ".$rArr ;

$sLine=str_replace("%m",$rArr ."[".$rArr."]",$sLine);

$sLine=str_replace("%g",$rArr ,$sLine);

$sLine.="
n";

if ($rArr >$lMax) $lMax=$rArr ;

$sCont=$sLine.$sCont;

}

if ($lMax>-1) @odbc_exec($ConnID,"UPDATE User SET FirstTime=False,LastLoc=".($lMax+1)." WHERE UserID=".$id);
