What do you mean set the file extension. You are opening updateItemCode it will open whatever extension updateItemCode is. If updateItemCode is a file then it should be in quotes like
$f= fopen("updateItemCode.html", 'a+');
Also, you should remove the @ in front if that because it will ignore errors and that can create debugging nightmares. Can you paste more code? If you want to keep the @ then you need to check to see if it is successful as in
if($f = @fopen(updateItemCode, "a+"){
//then do something
}
else{
//there was an error in opening the file
//which is what I'm guessing your problem is
}
