Cache Laravel Package

Getting Started

• Confirm the package still resolves before anything else. The upstream repository is not publicly linked for this listing, so treat Packagist as the source of truth: run composer show phpfluent/cache -a and check that the dist/source URLs are reachable. If Composer cannot fetch it, the package is archival — vendor a copy or stop here.
• Read three files, in order: composer.json (PHP constraint — a January 2018 release almost certainly targets PHP 7.x), the fluent entry class in src/, and any driver/adapter directory. The README is likely the only API documentation; copy it into your project before it disappears.
• Read the tests if any exist. In a small fluent library, the test suite is the reference for chain order (driver → TTL → key → value) and for how remember behaves on a cache hit.
• First use case — one round trip: cache a single expensive, idempotent value (a rendered report, a remote API payload), set a TTL, and read it twice. If the second read does not touch the origin, you have validated the chain, the TTL semantics, and the driver's serialization in one step.

A minimal bootstrap will look roughly like this — confirm the real entry class and chain order against the README, since fluent APIs are order-sensitive and there is no standard here:

$cache = new \PhpFluent\Cache\Cache(/* driver name or config array */);

$report = $cache->driver('file')
    ->ttl(300)
    ->remember('report:42', fn () => buildReport(42));

Implementation Patterns

Cache-aside via remember. This is the package's core value proposition and how you will use it 80% of the time. Keep the closure pure and side-effect-free — anything that writes other cache keys or mutates state will produce confusing behavior on the hit path.

A single key factory. Because this is a fluent string-key cache, key collisions are the primary operational hazard. Route every key through one helper:

function cacheKey(string $entity, $id, int $version = 1): string
{
    return sprintf('%s:%s:%s:v%d', getenv('APP_ENV'), $entity, $id, $version);
}

Prefixing with environment lets multiple apps share one Redis instance safely.

Driver swap per environment. Array or null driver in tests, file driver locally, Redis/Memcached in production. Bind the cache as a singleton in your container (or the framework's service container) and inject it — do not instantiate it at call sites, or you lose the ability to swap drivers in tests.

Wrap it behind PSR-16. Unless the package already implements Psr\SimpleCache\CacheInterface (verify with instanceof), write a thin adapter that does. This costs an hour and gives you a migration path off an unmaintained 2018 dependency without touching call sites.

Versioned keys instead of pattern deletes. Most backends do not support delete('prefix:*'). When data changes shape or a deploy invalidates a cache, bump the version segment in the key factory. It is atomic and driver-agnostic.

Test with the array driver and frozen time. Use the in-memory driver, clear it in setUp, and assert explicitly that your origin callable fired exactly once across two reads. For TTL, either inject a clock or keep TTLs short enough to actually expire within the test.

Explicit invalidation on write. After mutating an entity, call forget with the same key factory output. Do not rely on TTL expiry for correctness-sensitive reads.

Gotchas and Tips

• Unmaintained since January 2018 and an unknown repo is the headline risk. Pin the exact version in composer.json, and commit a vendored copy or a fork so a Packagist disappearance cannot break your build.
• PHP 8 will bite. A 2018 library may use each(), curly-brace string offsets, implicitly nullable parameters, or dynamic properties. Run php -d error_reporting=E_ALL and a static analyzer (PHPStan/Psalm) over vendor/phpfluent/cache before trusting it in production.
• Do not assume PSR conformance. "Fluent cache" is a description, not an interface. Check for Psr\SimpleCache\CacheInterface / Psr\Cache\CacheItemPoolInterface explicitly; if absent, wrap rather than patch the vendor.
• TTL conventions vary by driver. 0, null, -1, and omitted TTLs mean different things across file/Redis/Memcached backends. Test expiry behavior per driver, not just on the one you develop against. Watch for seconds-vs-minutes mismatches.
• Serialization is driver-dependent. File drivers typically serialize(); Redis may store raw strings. Objects containing closures, resources, or PDO handles will fail — cache scalars and plain arrays only.
• No built-in stampede protection. remember will not lock; under load a cold popular key can hammer your origin. Add a lock (Redis SET NX) around the expensive closure for hot keys.
• Debugging workflow: log the resolved driver, key, and TTL immediately before each call. If behavior is wrong, reproduce with the array driver to isolate the library from the backend, then dump the backend client directly.
• Config quirks: watch for a file driver with a hardcoded or relative cache path (breaks in containers/CI), and for missing defaults throwing instead of falling back.
• Transitive dependencies are stale. Audit composer.lock — a 2018 release may pin old predis/memcached versions that conflict with your stack.
• Extension points: if the package exposes driver registration, adding a driver is usually a single class implementing a small interface. If it does not, prefer decorating the public class over forking — it keeps your upgrade (or exit) path clean.
