Implementing State Machine On Eloquent Model*

* Update (12.09.2017): I have improved the trait so that it can be used with objects other than Eloquent Models.

Some days ago I came across a task where I needed to implement managable state for an Eloquent model. This is a common task, actually there is a mathematical model called "Finite-state Machine". The concept is that the state machine (SM) "can be in exactly one of the finite number of states at any given time". Also changing from one state to another (called transition) depends on fulfilling the conditions defined by its configuration.

Practically this means you define each state that the SM can be in and the possible transitions. To define a transition you set the states on which the transition can be applied (initial conditions) and the only state in which the SM should be after the transition.

That's the theory, let's get to the work.

Basic RESTful API with Symfony 3 + FOSRestBundle (JSON format only) + FOSUserBundle + FOSOauthServerBundle

The API we are creating in this gist will follow these rules :

• The API only returns JSON responses
• All API routes require authenticationu
• Authentication is handled via OAuth2 with password Grant Type only (no need for Authorization pages and such).
• API versioning is managed via a subdomain (e.g. v1.api.example.com)

The API will be written in PHP with the Symfony 3 framework. The following SF2 bundles are used :

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
