Caching Strategy Analysis

Analyze PHP code for caching opportunities and issues.

Detection Patterns

1. Missing Cache Opportunities

// CACHEABLE: Repeated expensive computation
public function getExchangeRate(string $currency): float
{
    return $this->api->fetchRate($currency); // API call each time
}

// CACHEABLE: Repeated database query
public function getSettings(): array
{
    return $this->repository->findAll(); // Same query repeatedly
