The ultimate tree library. For all your tree recursion needs.
Treeize::create($tree)->parse()->get();
Installation
You can install this library using composer
composer require odannyc/treeize
Usage
Given a simple array:
$tree = [ [ "id" => 1, "parent_id" => 0 ], [ "id" => 2, "parent_id" => 1 ], [ "id" => 3, "parent_id" => 1 ], [ "id" => 4, "parent_id" => 2 ], [ "id" => 5, "parent_id" => 2 ],[ "id" => 6, "parent_id" => 0 ], [ "id" => 7, "parent_id" => 6 ], [ "id" => 8, "parent_id" => 6 ] ]
You will be able to parse this tree and set it correctly recursively doing this:
Treeize::create($tree)->parse()->get();
The output will be:
[
[
"id" => 1,
"parent_id" => 0,
"children" => [
[
"id" => 2,
"parent_id" => 1,
"children" => [
[
"id" => 4,
"parent_id" => 2
],
[
"id" => 5,
"parent_id" => 2
]
]
],
[
"id" => 3,
"parent_id" => 1
],
]
],
[
"id" => 6,
"parent_id" => 0,
"children" => [
[
"id" => 7,
"parent_id" => 6
],
[
"id" => 8,
"parent_id" => 6
]
]
]
]
If you'd like to change the "children" key to any other string you can do so by chaining off the create method before parsing. So:
Treeize::create($tree)->childrenKey('nodes')->parse()->get();
There's other options to chain on that method, here's the whole list:
Treeize::create($tree) ->parentKey('pid') ->indexKey('id') ->parentId(0) ->childrenKey('nodes') ->parse(function($item) {//do stuff to item}) ->get();
parentKey
- Sets the parent key name: Default is "parent_key"
indexKey
- Sets the index key name: Default is "id"
parentId
- Sets the initial parent ID to search for: This is figured out if non is provided
childrenKey
- Sets the children key name as described above.
parse
- Accepts a callback function that you can apply to each item in the tree, an item is an array in this instance.
