How to Get Array From URL Encoded String? - php

Question

I'm sure this is a very easy thing but I couldn't find it in google for hours.
I'm new to ActionScript and I'm trying to obtain an array of variables from a string that is generated by a .php file.
my php file outputs this:
var1=42&var2=6&var3=string
And my ActionScript code is:
public function CallAjax_VARIABLES(url:String , the_array:Array)
{
var request:URLRequest = new URLRequest(url);
var variables:URLLoader = new URLLoader();
variables.dataFormat = URLLoaderDataFormat.VARIABLES;
variables.addEventListener(Event.COMPLETE, VARIABLES_Complete_Handler(the_array));
try
{
variables.load(request);
}
catch (error:Error)
{
trace("Unable to load URL: " + error);
}
}
function VARIABLES_Complete_Handler(the_array:Array):Function {
return function(event:Event):void {
var loader:URLLoader = URLLoader(event.target);
//the_array = loader.data; // this doesn't work.
//the_array = URLVariables.decode(loader); // this doesn't work either.
//trace(loader.data['var1']); // this outputs 42, so I'm getting the string from php.
};
}
I think you already understood this but, in the end, I want to have an array (In ActionScript) that will give me:
the_array['var1']=42;
the_array['var2']=6;
the_array['var3']="string";
What am I doing wrong? What should I do?
Thanks!
EDIT:
I'm trying to get variables FROM php TO ActionScript.
e.g. My PHP file correctly converts the array to an html query, But I don't know how to parse them in an array in ActionScript.

Answer 1

You should use URLVariables for this.
var vars:URLVariables = new URLVariables(e.target.data);
This way you can simply say:
trace(vars.var2); // 6
An array would be useless here as the result is associative rather than index based, though you can easily take all the values and throw them into an array with a simple loop:
var array:Array = [];
for(var i:String in vars)
{
array.push(vars[i]);
}

Answer 2

I think you are looking for parse_str function
parse_str($str, $output);

Answer 3

Sorry, I thought this was a PHP question. In ActionScript, try this:
var the_array:URLVariables = new URLVariables();
the_array.decode(loader.data);
trace(the_array.var1);
