Get Live currency value using Yahoo API

Hi,

Here is a simple PHP code, using which you can get the live currency Value from yahoo finance ( http://finance.yahoo.com/ )

In this example i am getting the value of US Dollar in Indian Rupees.

<?php
$from   = 'USD'; /*change it to your required currencies */
$to     = 'INR';
$url = 'http://finance.yahoo.com/d/quotes.csv?e=.csv&f=sl1d1t1&s='. $from . $to .'=X';
$handle = @fopen($url, 'r');

if ($handle) {
    $result = fgets($handle, 4096);
    fclose($handle);
}
$allData = explode(',',$result); /* Get all the contents to an array */
$dollarValue = $allData[1];

echo 'Value of $1 in Indian Rupees is Rs. '.$dollarValue;
?>
