DataTree container

The DataTree class implements a key-value tree container.

Examples

use NoreSources\DataTree;

$dataTree = new DataTree ({
	'key' => 'value',
	// Associative array becomes DataTree
	'node' => [
		'one' => 1
		// Non-associative values remains as-is (array),
		'two' => [ '二', 2 ],
		// Associative values becomes DataTree
		'three' => [
			'french' => 'trois',
			'spanish' => 'tres',
			'italian' => 'tre'
		]
	]
});

// Merge content of JSON file with existing data
$dataTree->load ('content.json', DataTree::MERGE_OVERWRITE);

// Element access is available through ArrayAccess, ContainerInterface, "->" operator and the getElement() method

var_dump ($dataTree['key']);
var_dump ($dataTree['node']['two']);

if ($dataTree->has ('key')) {
	$value = $dataTree->get ('key');
}

var_dump ($dataTree->node->three->italian);
var_dump ($dataTree->node->getElement('two'));
$dataTree->node->get('three')->setElement('german', 'drei');

var_dump ($dataTree->serialize()); // json
