在PHP中使用array()處理多貨幣系統時,可以考慮以下策略:
$currencies = array(
'USD' => 1.0,
'EUR' => 0.85,
'GBP' => 0.75
);
function convertCurrency($amount, $fromCurrency, $toCurrency, $currencies) {
$exchangeRate = $currencies[$toCurrency] / $currencies[$fromCurrency];
return $amount * $exchangeRate;
}
$amount = 100;
$fromCurrency = 'USD';
$toCurrency = 'EUR';
$convertedAmount = convertCurrency($amount, $fromCurrency, $toCurrency, $currencies);
echo "Converted amount: $convertedAmount $toCurrency";
通過這些策略,可以在PHP中有效地處理多貨幣系統,并實現貨幣之間的轉換和計算。
