This package based on native php arrays allows you to switch a tree type.
Supported types:
- Adjacency list
- Materialized path
- Nested set
- Associative array trees
See data examples
composer require vhood/tree-converter- php >=5.6
Usage example:
use Vhood\TreeType\Converter; use Vhood\TreeType\Type\AdjacencyList; $adjacencyList = [ [ 'id' => 1, 'name' => 'node1', 'parent_id' => null, ], [ 'id' => 2, 'name' => 'node2', 'parent_id' => 1, ], ]; $adjacencyListConverter = new Converter(new AdjacencyList($adjacencyList)); print_r($adjacencyListConverter->toAssociativeArrayTree('children', 'id')); // Array // ( // [0] => Array // ( // [id] => 1 // [name] => node1 // [children] => Array // ( // [0] => Array // ( // [id] => 2 // [name] => node2 // [children] => Array // ( // ) // ) // ) // ) // )See all types
Materialized path level calculation example:
use Vhood\TreeType\Converter; use Vhood\TreeType\Type\MaterializedPath; $materializedPath = [ [ 'name' => 'node1', 'path' => '/1/', ], [ 'name' => 'node2', 'path' => '/1/2/', ], ]; $materializedPathConverter = new Converter(new MaterializedPath($materializedPath)); print_r($materializedPathConverter->toMaterializedPath('path', '/', 'level')); // Array // ( // [0] => Array // ( // [name] => node1 // [path] => /1/ // [level] => 1 // ) // [1] => Array // ( // [name] => node2 // [path] => /1/2/ // [level] => 2 // ) // )Other features:
- nodes identification
- keys renaming
- keys removing
