USD to BTC conversion code

USD to BTC conversion code

So, I have looked everywhere and no one seems to have this specific problem.

I have set up a e-commerce store that is accepting BTC, So far the users can only see the price of the product in USD, however, I want the user to be able to click the USD price and convert it to BTC instantly. Like you can on a blockchain.info transaction.

For example:

Blockchain transaction conversion

So far, I have only been able to display the BTC price using Blockchain API.

I want the same effect as Blockchain on my price, or atleast under it.

(Snapshots of site below to give an idea of what I want)

The code I have to display the BTC price (If it helps, im a noob sorry)

<?php

  $url = "http://ift.tt/2ccYlWA";
  $stats = json_decode(file_get_contents($url), true);

  echo $stats['market_price_usd'];

  ?>

Price display:

<p >$200.50</p>
