Sending an NSMutable Array to a php script in iOS

问题

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:.

about NSURLConnection about NSURLRequest

Tyler, you can use the following piece of code to post data.

[NSMutableURLRequest* urlRequest = [NSMutableURLRequest requestWithURL:<your php url>];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:@"var1=val1&var2=val2"]; //Replace with your actual name/parm values
[[NSURLConnection alloc] initWithRequest:urlRequest delegate:self];

In order to send an NSMutableArray array, you should iterate the array and construct an NSString object containing the string representation of the array. Then you must set that string as the http body.
