Determine Variable Type

How could I go about telling if a variable is an array or a string?

var variablename:String = “blah”;

trace(typeof(variablename));

Yeah, but that returns as an object when it’s an array. Null is also classified as an object so it’s conflicting. Any other methods?

Any solutions?

var myString:String="djankey";
var myArray:Array=["djankey", "as-flash.com"];

Object.prototype.getTypeOf = function(obj){
    if (arguments.length) var my = obj;
    else var my = this;
    var t = ["Array","Boolean","Button","Color","Date","Function","LoadVars","MovieClip","Number","Object","Sound","String","TextField","TextFormat","XML","XMLSocket"];
    var i, l = t.length;
    for(i=0; i<l; i++) if (my.constructor == new [t[i]]().constructor) return t[i];
    return null;
}

trace(getTypeOf(myString));
trace(getTypeOf(myArray));

if (myVariable is Array){ trace(“true”); }

Go Joe! Thanks man.
