How can the output of hierarchical data stored in Nested Sets be formatted in PHP to match a specific visual representation, such as the example structure of the Bauteile in the forum post?

To format the output of hierarchical data stored in Nested Sets to match a specific visual representation, such as the example structure of the Bauteile in the forum post, you can use a recursive function to traverse the nested sets data and generate the desired output structure. This function should take into account the nested levels of the data and format it accordingly to create a hierarchical representation. 

function formatNestedSets($data, $parent_id = 0, $level = 0) {
    $output = '';
    
    foreach ($data as $item) {
        if ($item['lft'] > $parent_id && $item['rgt'] < $parent_id) {
            $output .= str_repeat('-', $level) . $item['name'] . "\n";
            $output .= formatNestedSets($data, $item['lft'], $level + 1);
        }
    }
    
    return $output;
}

// Assuming $nestedSetsData is the array containing the Nested Sets data
echo formatNestedSets($nestedSetsData);
