CURRENCY CONVERTER ( Exchange Rate )

I found this php function to convert your local currency to the currency that you wish to convert. This google api currency converter helps my development time. Thanks to google team who created this php function.

Function:

function exchangeRate( $amount, $currency, $exchangeIn )
{
$googleQuery = $amount . ' ' . $currency . ' in ' . $exchangeIn;
$googleQuery = urlEncode( $googleQuery );
$askGoogle = file_get_contents( 'http://www.google.com/search?q=' . $googleQuery );
$askGoogle = strip_tags( $askGoogle );
$matches = array();
preg_match( '/= (([0-9]|\.|,|\ )*)/', $askGoogle, $matches );
return $matches[1] ? $matches[1] : false;
}

Usage:

echo exchangeRate( 1 , 'USD' , 'EURO' );

Or you can also use this function from oscommerce, rate is gather from www.xe.com

Function:

function quote_xe_currency($to, $from , $amount) {
$page = file('http://www.xe.net/ucc/convert.cgi?Amount='.$amount.'&From=' . $from . '&To=' . $to);

$match = array();

preg_match('/[0-9.]+\s*' . $from . '\s*=\s*([0-9.]+)\s*' . $to . '/', implode('', $page), $match);

if (sizeof($match) > 0) {
return $match[1];
} else {
return false;
}
}

Usage:

echo quote_xe_currency("USD","EURO","1");

smile!
