Question

I am making an iPhone app which needs to send a couple of arrays to a php script and then the php script needs to take the value(s) of those arrays and write an xml file. I know how to write the xml file with php, but I am unsure how to send the data to the php script from the iOS app…

Is it even possible to send a php script a couple of integer arguments from iOS? Sorry I am very new to php and iOS (programming in general for that matter).

Thanks

make GET or POST request from iOS app

example:

NSURL *url = [NSURL URLWithString:@"http://www.site.com/sendData.php"];

        NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url 
                                                                  cachePolicy:NSURLRequestReloadIgnoringCacheData 
                                                              timeoutInterval:60];

        [theRequest setHTTPMethod:@"POST"];     
        [theRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

        NSString *postData = [NSString stringWithFormat:@"name1=%@&name2=%@", data1, data2];

        NSString *length = [NSString stringWithFormat:@"%d", [postData length]];    
        [theRequest setValue:length forHTTPHeaderField:@"Content-Length"];  

        [theRequest setHTTPBody:[postData dataUsingEncoding:NSASCIIStringEncoding]];

        NSURLConnection *sConnection = [NSURLConnection connectionWithRequest:theRequest delegate:self];    
        [sConnection start];

In order to download the contents of a URL, an application needs to
provide a delegate object that, at a minimum, implements the following
delegate methods: connection:didReceiveResponse:,
connection:didReceiveData:, connection:didFailWithError: and
connectionDidFinishLoading:.
