💡 Real-World Examples
---------------------

[](#-real-world-examples)

### E-commerce Rewards Program

[](#e-commerce-rewards-program)

```
// Setup category-based earning
$rulesEngine->addEarningRule(new CategoryMultiplierRule('electronics', 3.0));
$rulesEngine->addEarningRule(new CategoryMultiplierRule('books', 2.0));
$rulesEngine->addEarningRule(new CategoryMultiplierRule('groceries', 1.5));

// Tier-based bonuses
$rulesEngine->addEarningRule(new TierBonusRule('gold', 1.25));
$rulesEngine->addEarningRule(new TierBonusRule('platinum', 1.5));

// Customer purchases $200 laptop (electronics + gold tier)
$result = $loyaltyService->earnPoints(
    $goldCustomerId,
    Money::fromDollars(200.00, Currency::USD()),
    TransactionContext::earning('electronics')
);
// Earns: 200 * 100 * 3.0 * 1.25 = 75,000 points

### Restaurant Chain Program

// Happy hour promotions
$happyHourRule = new TimeBasedRule(
    new DateTimeImmutable('2025-01-01 14:00:00'),
    new DateTimeImmutable('2025-12-31 17:00:00'),
    2.0, // Double points
    ConversionRate::standard(),
    ['monday', 'tuesday', 'wednesday']
);

$rulesEngine->addEarningRule($happyHourRule);

// Customer orders during happy hour
$result = $loyaltyService->earnPoints(
    $customerId,
    Money::fromDollars(12.50, Currency::USD()),
    TransactionContext::earning('food', 'mobile_app')
);
// Earns: 12.50 * 100 * 2.0 = 2,500 points

### SaaS Referral Program

// Referral bonus
$result = $loyaltyService->earnPoints(
    $referrerId,
    Money::zero(Currency::USD()), // No monetary transaction
    TransactionContext::create([
        'type' => 'referral_conversion',
        'referred_customer' => 'new_customer_789',
        'subscription_tier' => 'pro'
