Hi all, I really need some help getting values from the usps api

Well not getting them but using them.

 

I get the values but I need to extract the info to use in a form.

 

This is the class im using

<?php
require_once("xmlparser.php");

class USPS {

    var $server = "http://testing.shippingapis.com/ShippingAPITest.dll";
    var $user = "****";
    var $pass = "****";
    var $service = "";
    var $dest_zip;
    var $orig_zip;
    var $pounds;
    var $ounces;
    var $container = "None";
    var $size = "REGULAR";
    var $machinable;
    var $country = "USA";
    
    function setServer($server) {
        $this->server = $server;
    }

    function setUserName($user) {
        $this->user = $user;
    }

    function setPass($pass) {
        $this->pass = $pass;
    }

    function setService($service) {
        /* Must be: Express, Priority, or Parcel */
        $this->service = $service;
    }
    
    function setDestZip($sending_zip) {
        /* Must be 5 digit zip (No extension) */
        $this->dest_zip = $sending_zip;
    }

    function setOrigZip($orig_zip) {
        $this->orig_zip = $orig_zip;
    }

    function setWeight($pounds, $ounces=0) {
        /* Must weight less than 70 lbs. */
        $this->pounds = $pounds;
        $this->ounces = $ounces;
    }

    function setContainer($cont) {
        $this->container = $cont;
    }

    function setSize($size) {
        $this->size = $size;
    }

    function setMachinable($mach) {
        /* Required for Parcel Post only, set to True or False */
        $this->machinable = $mach;
    }
    
    function setCountry($country) {
        $this->country = $country;
    }
    
    function getPrice() {
        if($this->country=="USA"){
            // may need to urlencode xml portion
            $str = $this->server. "?API=RateV2&XML=<RateV2Request%20USERID=\"";

}
class error

}
class price
{
    var $mailservice;
    var $rate;
}
class intPrice
{
    var $id;
    var $rate;
}
?>

This is how Im getting the info

<?php
require("usps.php");

$usps = new USPS;
//http://production.shippingapis.com/ShippingAPI.dll
//http://testing.shippingapis.com/ShippingAPITest.dll
$usps->setServer("http://production.shippingapis.com/ShippingAPI.dll");
$usps->setUserName("****");
//Express, First Class, Priority, Parcel, Library, BPM, Media, or ALL
$usps->setService("All");
$usps->setDestZip("21061");
$usps->setOrigZip("85284");
$usps->setWeight(4, 2);
$usps->setContainer("Flat Rate Box");
$usps->setCountry("USA");
$usps->setMachinable("true");
$usps->setSize("Regular");
$price = $usps->getPrice(); 
print_r($price);

?>

and that gives me this result

USPS Object

    [list] => Array
        (
            [0] => price Object
                (
                    [mailservice] => Express Mail Hold For Pickup
                    [rate] => 49.70
                )

            [1] => price Object
                (
                    [mailservice] => Express Mail
                    [rate] => 49.70
                )

                    [rate] => 18.35
                )

            [5] => price Object
                (
                    [mailservice] => Priority Mail Flat Rate Envelope
                    [rate] => 4.95
                )

            [6] => price Object
                (
                    [mailservice] => Priority Mail Small Flat Rate Box
                    [rate] => 5.20
                )

            [7] => price Object
                (
                    [mailservice] => Priority Mail Medium Flat Rate Box
                    [rate] => 10.95
                )

            [8] => price Object
                (
                    [mailservice] => Priority Mail Large Flat Rate Box
                    [rate] => 14.95
                )

            [9] => price Object
                (
                    [mailservice] => Parcel Post
                    [rate] => 12.29
                )

            [10] => price Object
                (

                    [rate] => 4.05
                )

            [11] => price Object
                (
                    [mailservice] => Library Mail
                    [rate] => 3.85
                )

        )

)

 

I would like to be able to just pull out some of the mailservice and rate portions to use them later on in the form, like say a dropdown box but I do not know how to just isolate each item.

 

For instance turn that result into a 3 item select box with these options

Express Mail - $49.70

Priority Mail - $18.35

Parcel Post - $12.29

 

Hope that makes sense. Any help appreciated.
