What are some best practices for integrating blockchain.info API into a PHP website?

When integrating the blockchain.info API into a PHP website, it is important to securely handle API keys and user inputs to prevent any security vulnerabilities. Additionally, make sure to validate and sanitize all user inputs to prevent any potential injection attacks. Finally, consider implementing proper error handling to gracefully handle any API errors or issues that may arise during the integration process. 

// Example code snippet for integrating blockchain.info API into a PHP website

// Set your blockchain.info API key
$api_key = 'YOUR_API_KEY';

// Make a request to the blockchain.info API
$url = 'https://api.blockchain.info/v2/receive?xpub=YOUR_XPUB&callback=YOUR_CALLBACK_URL&key=' . $api_key;

$response = file_get_contents($url);

if($response){
    $data = json_decode($response, true);
    // Process the API response data here
} else {
    // Handle API request error
    echo 'Error: Unable to fetch data from blockchain.info API';
}
