货币在PHP中从INR转换为USD

我想在
PHP中将货币从INR转换为USD,这是我迄今为止尝试过的代码.但它不起作用.我错过了什么？

function currency($from_Currency,$to_Currency,$amount) {
	$amount = urlencode($amount);
	$from_Currency = urlencode($from_Currency);
	$to_Currency = urlencode($to_Currency);
	$url = "http://www.google.com/ig/calculator?hl=en&q=$amount$from_Currency=?$to_Currency";
	$ch = curl_init();
	$timeout = 0;
	curl_setopt ($ch, CURLOPT_URL, $url);
	curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($ch,  CURLOPT_USERAGENT , "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
	curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
	$rawdata = curl_exec($ch);
	curl_close($ch);
	$data = explode('"', $rawdata);
	$data = explode('"', $data['3']);
	$var = $data[0];
	return round($var,3);
}

$amount=130;

$from='INR';

$to='USD';

echo currency($from,$to,$amount);

最佳答案 谷歌将URL更改为

https://www.google.com/finance/converter?a

所以我发现的修复方法如下.

$amount = 1.00;
$from_Currency = 'USD';
$to_Currency = 'INR';
$amount = urlencode($amount);
$from_Currency = urlencode($from_Currency);
$to_Currency = urlencode($to_Currency);
$get = file_get_contents("https://www.google.com/finance/converter?a=$amount&from=$from_Currency&to=$to_Currency");
$get = explode("<span class=bld>",$get);
$get = explode("</span>",$get[1]);
echo $converted_amount = preg_replace("/[^0-9\.]/", null, $get[0]);
