Requirements

To use Circulon in your projects, you will just require PHP 5.6 or later.

Composer install

You can install this package by using Composer. Link to Packagist: https://packagist.org/packages/usox/circulon

composer require usox/circulon

Usage

Simply add your dependencies as follows:

$resolver = new \Usox\Circulon\Circulon();
$resolver
  ->addDependency('foo', 'bar')
  ->addDependency('foobar', [])
  ->addDependency('baz', [])
  ->addDependency('bar', ['baz', 'foobar']);

Calling resolve() will return the dependencies in order.

$list = $resolver->resolve();

var_dump($list);

array(4) {
  [0] =>
  string(3) "baz"
  [1] =>
  string(6) "foobar"
  [2] =>
  string(3) "bar"
  [3] =>
  string(3) "foo"
}

Circular dependencies

$resolver
  ->addDependency('foo', 'bar')
  ->addDependency('bar', 'baz')
  ->addDependency('baz', 'foo');

$resolver->resolve();

Circulon detects the circular dependency and throws a CircularDependencyException with message Circular reference for baz => foo.
