Are there any potential legal issues with scraping data from websites to obtain exchange rates in PHP?

One potential legal issue with scraping data from websites to obtain exchange rates in PHP is that it may violate the website's terms of service or copyright laws. To solve this issue, it is important to check the website's terms of service for any restrictions on data scraping and obtain permission if necessary. Additionally, consider using APIs provided by reputable sources for obtaining exchange rates instead of scraping data from websites without permission. 

// Example of using a reputable API to obtain exchange rates instead of scraping data from websites
$api_url = 'https://api.exchangerate-api.com/v4/latest/USD';

$response = file_get_contents($api_url);
$data = json_decode($response, true);

if ($data && isset($data['rates'])) {
    $exchange_rates = $data['rates'];
    
    // Use the exchange rates data as needed
    foreach ($exchange_rates as $currency => $rate) {
        echo "1 USD is equal to {$rate} {$currency}\n";
    }
} else {
    echo "Failed to retrieve exchange rates from API\n";
}
