When managing keys and setting up the environment for GnuPG encryption in PHP, it is important to follow best practices to ensure the security of the encryption process. This includes securely storing and managing keys, using strong passphrases, and setting up the environment properly to handle encryption and decryption operations. 

<?php

// Generate a new key pair
$gpg = new gnupg();
$gpg->addencryptkey("recipient@example.com");
$gpg->adddecryptkey("passphrase");

// Encrypt a message
$encrypted_message = $gpg->encrypt("Hello, world!");

// Decrypt a message
$decrypted_message = $gpg->decrypt($encrypted_message);
