What are the potential risks of encrypting PHP code for user data protection?

Encrypting PHP code for user data protection can introduce potential risks such as making it harder to debug and maintain the code, as well as potentially slowing down the performance of the application. Additionally, if the encryption key is compromised, it can lead to a security breach and expose sensitive user data. 

// Sample code snippet for encrypting user data
$plaintext = "Hello, world!";
$key = "secretkey";
$method = "AES-256-CBC";

$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length($method));
$ciphertext = openssl_encrypt($plaintext, $method, $key, 0, $iv);
$encrypted_data = base64_encode($iv . $ciphertext);

// Decrypting the data
$decoded_data = base64_decode($encrypted_data);
$iv_length = openssl_cipher_iv_length($method);
$iv = substr($decoded_data, 0, $iv_length);
$ciphertext = substr($decoded_data, $iv_length);
$decrypted_data = openssl_decrypt($ciphertext, $method, $key, 0, $iv);

echo $decrypted_data; // Output: Hello, world!
