Stupid question about arrays

Question

So I was messing in PHP the last few weeks and I like how they do their arrays, essentially mapping a value to value:

    public function setParams(array $params)
    {
        foreach ($params as $key=>$value) {
            $this->setParam($key, $value);
        }
        return $this;
    }

My question is, if I wanted to do this in AS3.0 I would do something like:

public function setParams(params:Array){

foreach (params as //something)

{

setParams(key:String, value:String);

}

Can some one fill in the //something spot for me, thats where Im stuck >_>

thanks.

if you want to pass an array of key,value,key,value, then do so. there's no significant difference from what i showed:

public function(keyvalueA:Array):Object{

var obj:Object={};

for(var i:int=0;i<keyvalueA.length;i+=2){

obj[keyvalueA]=keyvalueA[i+1];

}

return obj;

}

if the values are arrays, you would use the following to trace all the array elements of all the value arrays:
public function(keyvalueA:Array):Object{
var obj:Object={};
for(var i:int=0;i<keyvalueA.length;i+=2){
obj[keyvalueA]=keyvalueA[i+1];
if(keyvalueA[i+1] is Array){
for(var j:int=0;j<keyvalueA[i+1].length;j++){
trace("value:",i,"element:",j,keyvalueA[i+1]);
}
}
}
return obj;
}

use an associative array (ie, object):public function(keyA:Array,valueA:Array):Object{// error check to ensure keyA.length==valueA.lengthvar obj:Object={};for(var i:int=0;i<keyA.length;i++){obj[keyA]=valueA;}return obj;}
