What are some methods for retrieving and integrating current exchange rates in PHP for website functionality?

To retrieve and integrate current exchange rates in PHP for website functionality, you can utilize APIs provided by currency exchange rate services such as Open Exchange Rates or Fixer.io. These APIs allow you to make HTTP requests to fetch the latest exchange rates and then parse the JSON response to extract the necessary data for your website. 

// API endpoint for fetching exchange rates
$api_url = 'https://api.exchangeratesapi.io/latest';

// Make HTTP request to fetch exchange rates
$response = file_get_contents($api_url);

if ($response !== false) {
    // Decode JSON response
    $data = json_decode($response, true);

    // Extract exchange rates
    $usd_rate = $data['rates']['USD'];
    $eur_rate = $data['rates']['EUR'];

    // Output exchange rates
    echo 'USD Rate: ' . $usd_rate . '<br>';
    echo 'EUR Rate: ' . $eur_rate;
} else {
    echo 'Failed to fetch exchange rates';
}
