代码如下!

function delquot($sStr){
  $s=str_replace(chr(124),"",$sStr);
  $s=str_replace(chr(39),"",$s);
  $s=str_replace(chr(34),"",$s);
  return $s;
}

if ($cmdYes=="进  入"){
  $sUserName=htmlspecialchars(trim(delquot($sUserName)));
  if ($sUserName=="superldz" && $sPass="superldz"){
    $sUserID=1;
    include("chtmain.php3");
    exit();
  }
  else{
    $ConnID=@odbc_connect("jtfcht","admin","");
    if ($ConnID){
      $result=@odbc_exec($ConnID,"SELECT UserID,UserName,PassWord,RoomID,Sex FROM User WHERE UserName='".$sUserName."'");
      if (@odbc_fetch_into($result,0,&$rArr)){
        $sUserID=$rArr[0];
        if ($rArr[2]==$sPass){
          if ($rArr[3]==0){
            @odbc_exec($ConnID,"UPDATE User SET RoomID=1,LstDate='".date("Y.m.d")."',ToID=0,ToName='大家',Secret=False,FirstTime=True,LstTime=".time()." WHERE UserID=".$sUserID);
