How can PHP beginners ensure the security of their encrypted document IDs when using base64_encode and serialize functions?

To ensure the security of encrypted document IDs when using base64_encode and serialize functions, beginners should consider adding additional encryption layers, such as using a secret key or hashing the IDs before encoding them. This will add an extra layer of security to prevent unauthorized access to the document IDs. 

<?php

// Secret key for additional encryption
$secretKey = "mySecretKey";

// Document ID to be encrypted
$documentId = 12345;

// Encrypt the document ID with an additional layer of security
$encryptedId = base64_encode(hash('sha256', $documentId . $secretKey, true));

// Decrypt the encrypted ID
$decryptedId = substr(hash('sha256', base64_decode($encryptedId) . $secretKey, true), 0, -1);

// Output the encrypted and decrypted IDs
echo "Encrypted ID: " . $encryptedId . "<br>";
echo "Decrypted ID: " . $decryptedId;

?>
