Actionscript 3 - Reading String from PHP echo - php

Question

i have a php script that print with echo this:
'&string="tom,dick,harry"'
and i need to put the "tom,dick,harry" in an actionscript string, that i have to split in an array. I'm having problems reading the php output, i'm using the URLLoader and TheURLVariables Classes in this way
var myRequest:URLRequest = new URLRequest("ip/directory/script.php");
var myLoader:URLLoader = new URLLoader();
function onLoaded(event:Event):void {
var variables:URLVariables = new URLVariables( event.target.data );
modelli = variables.string.split(",");
caricaColori(modelli[0]);
}
myLoader.addEventListener(Event.COMPLETE, onLoaded);
myLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
myLoader.load(myRequest);
What am i doing wrong?

Answer 1

Thought that you got problem with URLVariables, I still not totally understand this yet
function onLoaded(event:Event):void {
var variables:URLVariables = new URLVariables( event.target.data );
modelli = variables.string.split(",");
caricaColori(modelli[0]);
}
why do you need to store it into a URLVariables instance? Why don't parse it directly. If you are afraid of the "&string=", you don't need to echo it on PHP side, or can slice it out on Actionscript side.
modelli = event.target.data.split(",");

Answer 2

Perhaps using a variable name that isn't reserved might help. string seems like a bad choice.

Answer 3

// in php change
echo '&string="tom,dick,harry"'
// to
echo "tom,dick,harry"
// in actionscript change
function onLoaded(event:Event):void {
var str:String = event.target.data;
modelli = str.split(",");
caricaColori(modelli[0]);
}
If you want to add more variables and whatever, I would suggest turning the php response into an xml file. URLVariables should be used to SEND data to the server not for parsing a server response.

function onLoaded(event:Event):void {
var variables:URLVariables = new URLVariables( event.target.data );
modelli = variables.string.split(",");
caricaColori(modelli[0]);
}
Your problem is that you're loading the variables into a URLVariables container, and then trying to call a string function on it. I would do it this way instead:
function onLoaded(event:Event):void {
//load data as a string
var variables:String = event.target.data;
//make a new array
var modelli:Array = new Array();
modelli = variables.split(",");
//possibly pop the array
modelli.pop(); //pop off the last empty element of array
caricaColori(modelli[0]);
}
There's also a good chance that when you load this PHP data, you'll need to pop() the last element off of the array because it will be an empty string.
