DHL Rate calculation
<p>In my website(php based) I want implement a rate calculator of DHL. I want to add 3 fields-1.Origin, 2.Destination and 3.Weight. These 3 values will be sent to DHL server and in return I want to have the RATE. How can I do that? </p>

<p>In another section, I will add more field (address, product hts code, etc.) with those 3 to get the RATE. How can it be done also??</p>
