使用PHP货币转换 [英] Currency Conversion using PHP

问题描述

我正在寻找一种方式来任何金额从一种货币转换到另一个网站上。用户可以输入类似100，然后选择美元作为货币，然后选择澳大利亚或加元作为货币转换为。当他点击转换按钮，我想这个数额自动转换，通过一些API，并展示了他的货币，他选择将其转换为量。

I'm looking for a way to convert any amount from one currency to another on a website. The user would enter something like '100' and select USD as the currency, and then chooses Australian or Canadian dollars as the currency to convert to. When he clicks the 'Convert' button, I'd like to convert that amount automatically, through some API, and show him the amount in the currency he chose to convert to.

任何想法？

推荐答案

片段

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,2);
}

您不必然需要，虽然卷曲。 的file_get_contents 应该做的太多，如果在 allow_furl_open 已启用：

You dont necessarily need cURL for that though. file_get_contents should do too if the allow_furl_open is enabled:

$result = file_get_contents(
    'http://www.google.com/ig/calculator?hl=en&q=100EUR=?USD'
);

这将返回类似

{lhs: "100 Euros",rhs: "129.18 U.S. dollars",error: "",icc: true}
