How can recursion be implemented to handle multiple dimensions in a PHP template system without sacrificing performance?

When dealing with multiple dimensions in a PHP template system, recursion can be used to traverse through nested arrays or objects without sacrificing performance. By creating a recursive function that can handle arrays of any depth, you can efficiently loop through the data and output the desired content in the template. 

function recursive_render($data) {
    if (is_array($data)) {
        foreach ($data as $key => $value) {
            if (is_array($value)) {
                recursive_render($value);
            } else {
                echo "<div>{$key}: {$value}</div>";
            }
        }
    }
}

$data = [
    'name' => 'John Doe',
    'age' => 30,
    'address' => [
        'street' => '123 Main St',
        'city' => 'New York',
        'zipcode' => '10001'
    ]
];

recursive_render($data);
