What are the advantages of using nested arrays in PHP for generating complex HTML structures?

When generating complex HTML structures in PHP, using nested arrays can help organize the data in a hierarchical manner, making it easier to manage and manipulate the structure. This approach allows for a more modular and scalable codebase, as well as making it simpler to iterate over the data and generate the corresponding HTML output. 

// Example of using nested arrays to generate a complex HTML structure

$html = [
    'div' => [
        'attributes' => ['class' => 'container'],
        'children' => [
            [
                'tag' => 'h1',
                'text' => 'Hello, World!'
            ],
            [
                'tag' => 'ul',
                'children' => [
                    [
                        'tag' => 'li',
                        'text' => 'Item 1'
                    ],
                    [
                        'tag' => 'li',
                        'text' => 'Item 2'
                    ],
                    [
                        'tag' => 'li',
                        'text' => 'Item 3'
                    ]
                ]
            ]
        ]
    ]
];

function generateHtml($element) {
    $html = '';

    if (isset($element['tag'])) {
        $html .= '<' . $element['tag'];

        if (isset($element['attributes'])) {
            foreach ($element['attributes'] as $attr => $value) {
                $html .= ' ' . $attr . '="' . $value . '"';
            }
        }

        $html .= '>';
        
        if (isset($element['text'])) {
            $html .= $element['text'];
        }

        if (isset($element['children'])) {
            foreach ($element['children'] as $child) {
                $html .= generateHtml($child);
            }
        }

        $html .= '</' . $element['tag'] . '>';
    }
