使用PHP进行货币换算
使用PHP进行货币换算
提问于 2010-07-19 23:41:41
我正在寻找一种方法来转换任何金额从一个货币到另一个网站上。用户将输入类似于'100‘的内容，并选择USD作为货币，然后选择澳元或加拿大元作为要转换为的货币。当他点击“转换”按钮时，我想通过一些API自动转换金额，并向他显示他选择转换为的货币金额。
有什么想法吗？

此方法使用Yahoo currency API完整教程：Currency Converter in PHP, Python, Javascript and jQuery
function currencyConverter($currency_from, $currency_to, $currency_input) {
$yql_base_url = "http://query.yahooapis.com/v1/public/yql";
$yql_query = 'select * from yahoo.finance.xchange where pair in ("' . $currency_from . $currency_to . '")';
$yql_query_url = $yql_base_url . "?q=" . urlencode($yql_query);
$yql_query_url .= "&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
$yql_session = curl_init($yql_query_url);
curl_setopt($yql_session, CURLOPT_RETURNTRANSFER, true);
$yqlexec = curl_exec($yql_session);
$yql_json = json_decode($yqlexec, true);
$currency_output = (float) $currency_input * $yql_json['query']['results']['rate']['Rate'];
return $currency_output;
}
$currency_input = 2;
//currency codes : http://en.wikipedia.org/wiki/ISO_4217
$currency_from = "USD";
$currency_to = "INR";
$currency = currencyConverter($currency_from, $currency_to, $currency_input);
echo $currency_input . ' ' . $currency_from . ' = ' . $currency . ' ' . $currency_to;Stack Overflow用户

在搜索了很多次之后，找到了这个。
// Fetching JSON
$req_url = 'https://api.exchangerate-api.com/v4/latest/USD';
$response_json = file_get_contents($req_url);
// Continuing if we got a result
if(false !== $response_json) {
// Try/catch for json_decode operation
try {
// Decoding
$response_object = json_decode($response_json);
// YOUR APPLICATION CODE HERE, e.g.
$base_price = 12; // Your price in USD
$EUR_price = round(($base_price * $response_object->rates->EUR), 2);
}
catch(Exception $e) {
// Handle JSON parse error...
}
}这工作得很好。该代码片段来自：https://www.exchangerate-api.com/docs/php-currency-api

$xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA);
if($xml === FALSE)
{
//deal with error
}
else {
$rate = $xml;
