What are some best practices for structuring an array in PHP to represent a hierarchical tree-like structure?

When representing a hierarchical tree-like structure in PHP using an array, it is important to use a nested array structure where each node can have children nodes. This allows for easy traversal and manipulation of the tree. One common approach is to use an associative array where each node has a "children" key that contains an array of its children nodes. 

$tree = [
    'name' => 'Root',
    'children' => [
        [
            'name' => 'Node 1',
            'children' => [
                [
                    'name' => 'Node 1.1',
                    'children' => []
                ],
                [
                    'name' => 'Node 1.2',
                    'children' => []
                ]
            ]
        ],
        [
            'name' => 'Node 2',
            'children' => []
        ]
    ]
];
