swift php array to swift json - php

Question

I am trying to work with a swift code to pass vars to php and a response back to swift. this all goes smooth with the following code. This is just a simple peice of code to get things going. It gives me the correct connection and results, how ever i have to pass loads of data which should be in an array i guess. But when i try to send through more data in a array i don't see anything. In php i would explode the results to get them one by one but how do i get loads of values to variables so i can use them again?
below is my code
<?php
require('conn.php');
header('Content-type: application/json');
if($_POST) {
$database =trim ($_POST['database']);
$engine = trim($_POST['engine']);
$name = "William";
$results = Array("name" => $name
);
echo json_encode($results);
}/*end if POST*/
?>
this is the swift code
let data:NSString = ("bfdprofile" as NSString)
let engine:NSString = "account" as NSString
self.usernameLabel.text = prefs.valueForKey("USERNAME") as? String
let url = NSURL(string:"xxxxx.php")
let cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData
var request = NSMutableURLRequest(URL: url!, cachePolicy: cachePolicy, timeoutInterval: 2.0)
request.HTTPMethod = "POST"
// set Content-Type in HTTP header
let boundaryConstant = "----------V2ymHFg03esomerandomstuffhbqgZCaKO6jy";
let contentType = "multipart/form-data; boundary=" + boundaryConstant
NSURLProtocol.setProperty(contentType, forKey: "Content-Type", inRequest: request)
// set data
var dataString = "data=\(data)&engine=\(engine)"
let requestBodyData = (dataString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
request.HTTPBody = requestBodyData
// set content length
//NSURLProtocol.setProperty(requestBodyData.length, forKey: "Content-Length", inRequest: request)
var response: NSURLResponse? = nil
var error: NSError? = nil
let reply = NSURLConnection.sendSynchronousRequest(request, returningResponse:&response, error:&error)
if let results = NSJSONSerialization.JSONObjectWithData(reply!, options: nil, error: &error) as? [String: String]{
if let name = results["name"]{
labelTestOutput.text = name as? String
}
}
Thanks for the help

You can do it asynchronously with Alamofire library as simple as that:
typealias JSONdic = [String: AnyObject]
let param = ["data": "somedata", "engine": "someEngine"]
Alamofire.request(.POST, URLString: "xxxxx.php", parameters: param).responseJSON() {
(_,_,json,_) in
if let json = json as? JSONdic, name = json["name"] as? String {
// do something with name
}
}
