Post values to page and hardcode return

Hi all,

I have 2 pages PageA and pageB. PageA posts some values to pageB and pageB gets it.

Now, my problem is that the code is expecting a 0 or 1 as return...

Here is the code for pageA:

- (void)SubmitLogin
{    
    NSURL *url = [NSURL URLWithString:[(BakerClaimsAppDelegate*)[[UIApplication sharedApplication] delegate] GetLoginURL]];

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setPostValue:[userName text] forKey:@"username"];
    [request setPostValue:[password text] forKey:@"password"];
    [request setUploadProgressDelegate:self];
    [request setDelegate:self];
    [request startAsynchronous];
}

and PageB has:

$username = $_POST['username'];
$password = $_POST['password']; 

My question  is...how do I provide this return in from pageB to pageA in PHP?

I basically need pageA to think it's all ok by returning a 1 even if it's hardcoded.

Thanks
