How can PHP developers ensure that their encryption implementations are efficient and effective for data protection?

To ensure that encryption implementations are efficient and effective for data protection, PHP developers should use strong encryption algorithms, securely store encryption keys, and properly handle encrypted data. They should also consider performance implications when choosing encryption methods to avoid unnecessary overhead. 

// Example of using AES encryption with a secure key and initialization vector (IV)
$key = random_bytes(32); // Generate a secure random key
$iv = random_bytes(16); // Generate a secure random IV

$data = "Sensitive data to be encrypted";

$encrypted = openssl_encrypt($data, 'AES-256-CBC', $key, 0, $iv);

// Store $key and $iv securely for decryption
