Comparison Laravel Package

Product Decisions This Supports

• Standardizing "sort/filter" as a product contract. If your roadmap includes user-facing sorting or filtering (e.g. ?sort=price:desc, saved views, leaderboards, admin tables), this package is a candidate for the one place that defines ordering semantics. The PM decision it informs is: do we let each squad invent sort rules, or do we publish one comparable contract?
• Build vs. buy for comparison primitives. The honest framing is "buy vs. adopt": the alternative isn't a competitor product, it's 40 lines of usort + <=> in a shared support class. This package only wins the decision if you already buy into the php-standard-library family, or if you need a portable Comparable interface across many packages.
• A defect class, not a feature. Loose-vs-strict comparison bugs ("10" > "9" is false in PHP) show up as pricing errors, off-by-one tier boundaries, and inconsistent pagination. That's a quality/risk line item for the roadmap, and it's the strongest argument a PM has here — stronger than "developer productivity."
• Domain object ordering (DDD alignment). If domain objects like Money, Tier, EffectiveDate, or Version need ranked ordering (version precedence, price-tier bucketing, date-range overlap), a shared comparison contract reduces the chance two services sort them differently.
• Adoption/roadmap signal for the platform team. This is a 1-star, 0-dependent, single-maintainer split package. The decision it most directly supports is whether to take a dependency on the broader php-standard-library ecosystem — that's a platform-strategy call, not a feature call.

PM caveat to carry into any decision: the in-repo README contains no API documentation or usage examples — it only links to an external docs site. Any code samples circulating internally (e.g. Comparator::greaterThan(), Comparator::asc()) are inferred, not verified. Do not put method names in a stakeholder deck until an engineer has read the actual interface.

When to Consider This Package

Consider it if all of these hold:

• You are on PHP 8.1+ and already run static analysis (PHPStan/Psalm) in CI — the type-safety value only materializes if you enforce it.
• Comparison rules are repeated across multiple services or packages, not just multiple files in one app. Cross-boundary duplication is where a shared contract pays.
• You have at least one ranked domain concept with real business stakes (tier boundaries, price precedence, version ordering) where a bug is expensive.
• You have an owner willing to accept single-maintainer, pre-1.0-shaped risk and to pin versions and review changelogs on upgrade.
• You need a portable Comparable interface rather than a Laravel-specific helper.

Look elsewhere if any of these hold — for most Laravel apps, several will:

• You're a single Laravel application. Collection::sortBy, sortByDesc, sortBy([...]) for multi-key, Eloquent orderBy, and the spaceship operator already cover ~90% of this. Laravel's own primitives are the incumbent and they're free.
• Your comparisons happen in the database. This package cannot push ordering into SQL. If sorting/filtering is a query concern, orderBy plus indexes is the answer, and adopting a PHP-layer comparator actively risks inconsistent results between DB-sorted and app-sorted paths.
• You need deep/structural comparison of nested arrays or object graphs — reach for symfony/comparator, doctrine/collections, or spatie utilities instead.
• You need custom weighting or context-aware ordering (fuzzy matching, relevance scoring, business-tunable weights). That's a product-owned ranking service, not a utility package.
• You need an SLA, security review, or vendor accountability. One star and zero dependents means no external validation; the dependency is effectively a maintainer relationship, not an ecosystem bet.
• The team already resists abstraction over native operators. A package that must be enforced by code review creates ongoing friction cost with no product return.

My default recommendation: do not adopt as a platform dependency. Run a time-boxed 1–2 day spike on one bounded surface (a single API sort contract or one domain object's ordering) and measure whether the API is expressive enough to be worth the dependency. Decide on evidence, not on the README.

How to Pitch It (Stakeholders)

For executives — frame as a bounded experiment with a stop/go gate, not a rollout:

"We have a recurring class of bug where comparison logic is written differently in different places — pricing tiers, sort orders, eligibility checks — and inconsistent PHP comparison semantics can produce wrong results at boundaries. There's a small, MIT-licensed utility that standardizes this. Before committing, we're spending 1–2 engineering days proving it on one surface. If it doesn't measurably reduce duplication or risk, we standardize internally on Laravel's built-ins instead. Cost of finding out: two days. Cost of the status quo: recurring boundary bugs we can't currently count."

For engineering — lead with the honest trade-off:

"It's a thin comparison-contract package: interfaces plus helpers for strict, consistent comparison, zero dependencies, MIT. It's not a Laravel package — no Eloquent or Collection integration, so anything query-side stays with orderBy. It's a 1-star repo with a single maintainer, so we pin and we watch releases. The upside is one place to change ordering semantics across services and a natural home for Comparable on Money/Version/Tier. The proposal: spike it against one real sort contract, benchmark the hot path against the spaceship operator, and only adopt if the interface is clean and the overhead is negligible."

For developers — set the bar explicitly:

"If you've ever fixed a bug that came from == and === disagreeing, or from two services sorting Money differently, that's the target. Before we adopt anything, we need an engineer to read the actual interface (the repo's README has no API docs — it links out) and answer two questions: does it express our real ordering cases without casting gymnastics, and what does it cost per call in a large sort? If the answer is 'we could write this in a support class in an afternoon,' write the support class."

Guardrails I'd attach to any approval:

• Pin the exact version; no floating constraint.
• Add a CI rule or PHPStan rule if adopted — an unenforced abstraction is pure cost.
• Exit criterion written up front: measurable reduction in duplicated comparison logic, zero performance regression on the hottest sort path, and no dependency-driven delay in a release.
• Do not adopt for anything that resolves in SQL. Keep one source of truth for ordering — the database, or the app, not both.
