另一个基于免费政府数据源的简单自托管货币转换器
，但也同样可以添加其他数据源。

内置序列化和反序列化功能，允许您保存/缓存转换器及其最后更新时间戳，
从而在需要时避免不必要的请求。

安装

首先，您需要根据其网站上的说明安装Composer。

然后，只需运行以下命令

composer require vasilevich/currencyconverter

使用示例

<?php
require_once __DIR__ . "./vendor/autoload.php";

use vasilevich\currencyconverter\CurrencySourceBankOfEurope;
use vasilevich\currencyconverter\CurrencySourceBankOfIsrael;
use vasilevich\currencyconverter\CurrencySourceDenemarkNationalBank;
use vasilevich\currencyconverter\CurrencySourceFromSerialization;

$converter = new CurrencySourceBankOfEurope(); // use european bank
var_dump($converter->getCurrencyList()->convert("EUR", "USD", 1)); // -> 1 euro to usd through Europe bank
var_dump($converter->getCurrencyList()->convert("USD", "EUR", 1)); // -> 1 usd to euro through Europe bank
var_dump($converter->getCurrencyList()->convert("ILS", "EUR", 1)); // -> 1 ils to euro through Europe bank
var_dump($converter->getCurrencyList()->convert("EUR", "ILS", 1)); // -> 1 euro to ils through Europe bank
$converter = new CurrencySourceBankOfIsrael(); //use israeli bank
var_dump($converter->getCurrencyList()->convert("EUR", "USD", 1)); // -> 1 euro to usd through Israel Bank
var_dump($converter->getCurrencyList()->convert("USD", "EUR", 1)); // -> 1 usd to euro through Israel Bank
var_dump($converter->getCurrencyList()->convert("ILS", "EUR", 1)); // -> 1 ils to euro through Israel Bank
var_dump($converter->getCurrencyList()->convert("EUR", "ILS", 1)); // -> 1 euro to ils through Israel Bank

$converter = new CurrencySourceDenemarkNationalBank(); //use denemark national bank
var_dump($converter->getCurrencyList()->convert("EUR", "USD", 1)); // -> 1 euro to usd through Denemark national Bank
var_dump($converter->getCurrencyList()->convert("USD", "EUR", 1)); // -> 1 usd to euro through Denemark national Bank
var_dump($converter->getCurrencyList()->convert("ILS", "EUR", 1)); // -> 1 ils to euro through Denemark national Bank
var_dump($converter->getCurrencyList()->convert("EUR", "ILS", 1)); // -> 1 euro to ils through Denemark national Bank

$serializedConverter = $converter->serialize(); // convert the object to string, ready for caching/saving/transferring by your own logic
$unserializedConverter = new CurrencySourceFromSerialization($serializedConverter); //obtain the serialized converter from anywhere and deserialize the converter back into use
var_dump($unserializedConverter->getCurrencyList()->convert("ILS", "USD", 4));  //test converter
