title: xe.com currency conversion api
body: <p>i have a payment gateway in my website and i showcase the products with their prices in USD. But when users select a product to purchase, i need to convert the USD amount to INR as my payment gateway is allowing only Indian (INR) rates for transactions.</p>
  
  <p>Hence i need a live currency conversion code in php, that i can use prior to the purchase of the product. I have heard about many currency conversion scripts in php, but is there a code for xe.com currency conversion ?</p>
  
  <p>Please help... :)</p>
