What are the potential risks of using external IDs to hide database IDs in PHP sessions?

Using external IDs to hide database IDs in PHP sessions can introduce security vulnerabilities, as external IDs can potentially be manipulated or guessed by malicious users. To mitigate this risk, it is recommended to encrypt the database IDs before storing them in the session. 

// Encrypt the database ID before storing it in the session
$databaseId = 123; // This is the actual database ID
$encryptedId = encrypt($databaseId); // Implement your own encryption method here

$_SESSION['external_id'] = $encryptedId;

// Decrypt the database ID when needed
$decryptedId = decrypt($_SESSION['external_id']); // Implement your decryption method here
