This is how Im getting the info
Code: [Select]
<?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
Code: [Select]

                )

        )

)

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.
