How can PHP developers handle the issue of expired activation links in registration systems effectively?

Issue: Expired activation links in registration systems can be handled effectively by implementing a time limit on the activation links and checking the expiration time before allowing the user to activate their account. 

// Check if activation link has expired
$activation_link_expiry = 24 * 60 * 60; // 24 hours
$activation_link_time = strtotime($activation_link_created_time);
$current_time = time();

if (($current_time - $activation_link_time) > $activation_link_expiry) {
    // Activation link has expired, display error message
    echo "Activation link has expired. Please request a new one.";
} else {
    // Activate user's account
    // Your activation logic here
}
