What best practices should be followed when generating a tree view in PHP?

When generating a tree view in PHP, it is important to follow best practices to ensure efficient and organized code. One approach is to recursively iterate through the tree structure to build the view, ensuring proper indentation and hierarchy. Additionally, using HTML and CSS for styling can enhance the visual representation of the tree. 

function generateTreeView($nodes, $indent = 0) {
    foreach ($nodes as $node) {
        echo str_repeat('  ', $indent) . $node['name'] . '<br>';
        if (!empty($node['children'])) {
            generateTreeView($node['children'], $indent + 1);
        }
    }
}

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

generateTreeView($tree);
