iPhone到PHP到iPhone

I am trying to create a login system on an iPhone app but am coming across a bit of a problem. I believe that the code I have is sending the the NSString to the php but it is not echoing back the string like I want it to. What am I doing wrong?

I know the php code isn't doing much right now I just want to see that it is storing the values that I send it.

Thanks!

XCode:

    NSString *content = @"myusername=a&mypassword=s";

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://mywebsite.php"]];
    urlRequest = [[[NSMutableURLRequest alloc] init] autorelease];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody:[content dataUsingEncoding:NSISOLatin1StringEncoding]];


    // generates an autoreleased NSURLConnection
    [NSURLConnection connectionWithRequest:request delegate:self];

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
    NSLog(returnString);

}

PHP:

echo "first ". $_POST['myusename']." return";  
echo "second ". $_POST['mypassword']." return";

    You allocate 2 NSMutableURLRequest objects. I'll try to correct your mistake:

    NSString *content = @"myusername=a&mypassword=s";
    
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://mywebsite.php"]];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:[content dataUsingEncoding:NSISOLatin1StringEncoding]];
    ...
    

    Furthermore the string encodings do not match, that could cause problems.
