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

问题描述

我正在寻找一种方法，可以在网站上将任何金额从一种货币转换为另一种货币.用户将输入类似100"的内容并选择美元作为货币，然后选择澳元或加元作为要转换的货币.当他点击转换"按钮时，我想通过一些 API 自动转换该金额，并向他显示他选择转换为的货币金额.

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.

有什么想法吗?

推荐答案

找了很多，找到了这个.

After searching a lot, found this.

// 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...
    }
}
