It is not the best solution and not very clean, but you can do this:
Example for 100 EUR to USD:
100 EUR to Bitcoin. Result: 0.01282849
https://blockchain.info/tobtc?currency=EUR&value=100
Convert 01282849 (without "0.") to USD
https://blockchain.info/frombtc?value=01282849¤cy=USD
Attention: In this solution you can convert max 1 full Bitcoin (~8000 EUR)
PHP Code:
function convert($amount, $from, $to)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://blockchain.info/tobtc?currency=" . $from . "&value=" . $amount);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$conversion = curl_exec($ch);
$conversion = substr($conversion, 2);
curl_setopt($ch, CURLOPT_URL, "https://blockchain.info/frombtc?currency=" . $to . "&value=" . $conversion);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
return $conversion = curl_exec($ch);
}
echo convert(100, "EUR", "USD");
