SplitTest
=========

[](#splittest)

A lightweight PHP library for deterministic A/B and multivariate testing. Assign visitors to experiment variations using seed-based bucketing, keep their choice consistent across requests via cookies or headers, and plug in your own selection strategies whenever the defaults are not enough.

Features
--------

[](#features)

- **Deterministic bucketing** — the same seed always produces the same variation, so visitors see a consistent experience across sessions and requests.
- **Weighted distributions** — split traffic across any number of variations with arbitrary weights.
- **Pluggable chooser strategies** — ship with `Random`, `Balanced`, `Static` and `Callback` choosers, or implement your own via `ChooserInterface`.
- **Groups** — override the default variations for specific visitor cohorts (logged-in users, regions, feature flags, …).
- **String serialization** — round-trip experiments via cookies or headers with `fromString()` / `__toString()`.
- **Persistence helper** — `Container::deliver()` writes the assignment cookie and header in one call.
- **Selection callbacks** — hook variation assignment into your analytics or tracking pipeline.
- **Small surface area** — four model classes, four choosers, one container.

Requirements
