Until then beauty, but when i try the "foreach", it returns me this:
1
0
Root Catalog
0
0
Array
I need it to print the complete tree inside the tags <ul> <li>.
I'm use recursive foreach:
public function createTree($lists) {
echo '<ul>';
foreach ($lists as $list) {
echo '<li>';
echo $list['name'] . '';
echo '</li>';
if (is_array($list['children'])) {
$this->createTree($list['children']);
}
}
echo '</ul>';
}
U can help me? Tks!

You could try to wrap the output children array into li:
Wrap the $this->createTree($list['children'] into echo '<li>'; $this->createTree($list['children']); echo '</li>'
