How can beginners in PHP encryption ensure they are following proper encryption protocols and guidelines?

Beginners in PHP encryption can ensure they are following proper encryption protocols and guidelines by using established encryption functions and libraries such as OpenSSL. It is important to use strong encryption algorithms like AES and securely manage encryption keys. Additionally, always remember to properly handle sensitive data, such as securely storing encryption keys and avoiding storing plaintext passwords. 

// Example of encrypting data using OpenSSL with AES encryption

$data = "Hello, world!";
$key = openssl_random_pseudo_bytes(32); // Generate a secure random key
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cbc')); // Generate a secure random IV

$encrypted = openssl_encrypt($data, 'aes-256-cbc', $key, 0, $iv);

echo "Encrypted data: " . $encrypted;
