Question

I have a function generating nested navigation menu:

function recursive_foreach($array, $display) {
    $out = '<ul>';
    foreach ($array as $key => $value) {
        ... 
        $out .= '<li class="'. $is_active . $is_parent . '"><a href="' . $url . '">' . $value['name'] . '</a>'; }   
        if (is_array($value['has_children'])) { 
            $out .= recursive_foreach( ...
        }
        $out .= "</li>";
    }   
    $out .= '</ul>';    
    return $out;    
}

I want to add css class just to the first “ul” element. I know how to determine first element inside foreach loop but how can I get it outside of it?

Answer 1

Best pass an appropriate parameter:

function recursive_foreach($array, $display, $first = true) {
    ...
    recursive_foreach($foo, $bar, false);
    ...
}
