A PHP function to convert currencies in real time
This PHP function returns the conversion rate of 2 currencies in real time:
Example:
EUR/USD = get_conversion_rate('EUR', 'USD');
And this function converts an amount in US dollars to an amount in euros
(also in real time):
PHP Code:
function get_conversion_rate($currency1, $currency2) {
$fp = @fsockopen("download.finance.yahoo.com", 80, $errno, $errstr, 30);
if (!$fp) { return 1; }
else {
$file = "/d/quotes.csv";
$str = "?s=".$currency1.$currency2."=X&f=sl1d1t1ba&e=.csv";
$out = "GET ".$file.$str." HTTP/1.0\r\n";
$out .= "Host: yahoo.com\r\n";
$out .= "Connection: Close\r\n\r\n";
@fputs($fp, $out);
while (!@feof($fp)) { $data .= @fgets($fp, 128); }
@fclose($fp);
@preg_match("/^(.*?)\r?\n\r?\n(.*)/s", $data, $match);
$data = $match[2];
$search = array("'<script[^>]*?>.*?</script>'si", "'<[\/\!]*?[^<>]*?>'si", "'([\r\n])[\s]+'", "'&(quot|#34);'i", "'&(amp|#38);'i", "'&(lt|#60);'i", "'&(gt|#62);'i", "'&(nbsp|#160);'i", "'&(iexcl|#161);'i", "'&(cent|#162);'i", "'&(pound|#163);'i", "'&(copy|#169);'i", "'&#(\d+);'e");
$replace = array("", "", "\\1", "\"", "&", "<", ">", " ", chr(161), chr(162), chr(163), chr(169), "chr(\\1)");
$data = @preg_replace($search, $replace, $data);
$result = split(",", $data);
return $result[1]; } }
EUR/USD = get_conversion_rate('EUR', 'USD');
And this function converts an amount in US dollars to an amount in euros
(also in real time):
PHP Code:
function USD_to_EUR($amount) {
if (!defined('USD_EUR')) { define('USD_EUR', get_conversion_rate('USD', 'EUR')); }
$amount = round(100*USD_EUR*$amount)/100;
return $amount; }
