Create nested list from PHP array for dropdown select field

Answer 1

this just litle change of the original code that answered by Qeremy

function printTree($tree, $r = 0, $p = null) {
    foreach ($tree as $i => $t) {
        $dash = ($t['parent'] == 0) ? '' : str_repeat('-', $r) .' ';
        printf("\t%s%s\n", $t['id'], $dash, $t['name']);
        if (isset($t['_children'])) {
            printTree($t['_children'], $r+1, $t['parent']); 
        }
    }
}

Now the dashed name works great. *sorry for my english
