What are the advantages and disadvantages of storing complete activation links in a database versus only storing user IDs and generating links dynamically in PHP?

Storing complete activation links in a database allows for easy retrieval and verification, but it can potentially expose sensitive information if the database is compromised. On the other hand, generating links dynamically in PHP based on user IDs can enhance security by reducing the risk of exposure, but it may require additional processing time to generate and validate the links. 

// Storing complete activation links in a database
$activationLink = 'https://example.com/activate.php?token=abc123';
$sql = "INSERT INTO activation_links (user_id, activation_link) VALUES ('$userId', '$activationLink')";
// Execute SQL query to store activation link in database

// Generating links dynamically in PHP
$userId = 123;
$token = bin2hex(random_bytes(16)); // Generate a random token
$activationLink = 'https://example.com/activate.php?user_id=' . $userId . '&token=' . $token;
// Send activation link to user via email or other means
