README
The feature toggle library for PHP
Concept
Coming soon...
Usage
The Toggle
class is the core class. All feature config will set on this object.
Feature Toggle
Use the fixed result:
<?php use MilesChou\Toggle\Toggle; $toggle = new Toggle(); $toggle->create('f1', true); // Will return true $toggle->isActive('f1');
Use the object with fixed result:
<?php use MilesChou\Toggle\Feature; use MilesChou\Toggle\Toggle; $toggle = new Toggle(); $toggle->add('f1', Feature::create(true)); // Will return true $toggle->isActive('f1');
Use callable to decide the return dynamically:
<?php use MilesChou\Toggle\Toggle; $toggle = new Toggle(); $toggle->create('f1', function() { return true; }); // Will return true $toggle->isActive('f1');
Use callable with Context:
<?php use MilesChou\Toggle\Toggle; $toggle = new Toggle(); $toggle->create('f1', function($context) { return $context['return']; }); // Will return true $toggle->isActive('f1', ['return' => true]);
Parameters
Feature
instance can store some parameter. For example:
<?php use MilesChou\Toggle\Toggle; $toggle = new Toggle(); $toggle->create('f1', true, ['name' => 'Miles']); $toggle->create('f2', false, ['name' => 'Chou']); // Will return 'Chou' $toggle->feature('f1')->params('name'); // Also using in callback $toggle->create('f3', function($context, array $params) { return $params['key'] === $context['key']; }, ['key' => 'foo']);
Control Structure
This snippet is like if
/ switch
structure:
<?php use MilesChou\Toggle\Toggle; $toggle = new Toggle(); $toggle->create('f1'); $toggle->create('f2'); $toggle->create('f3'); $toggle ->when('f1', function ($context, $params) { // Something when f1 is on }) ->when('f2', function ($context, $params) { // Something when f2 is on }) ->when('f3', function ($context, $params) { // Something when f3 is on });
