What are the potential risks and vulnerabilities associated with transferring customer data between different servers in a PHP application?

Transferring customer data between different servers in a PHP application can pose risks such as data breaches, unauthorized access, and data corruption. To mitigate these risks, it is important to encrypt the data before transferring it and ensure secure communication channels are used. 

// Encrypt customer data before transferring
$customerData = "Sensitive customer data";
$encryptionKey = "super_secret_key";

$encryptedData = openssl_encrypt($customerData, 'AES-256-CBC', $encryptionKey, 0, 'random_init_vector');

// Transfer encrypted data securely
// code for transferring data securely goes here
