如何在HTML中使用递归循环将此数组显示为hieararchy组合框。我需要帮助才能解决这个问题
<option>- kakek</option>
<option>-- ayah</option>
<option>--- aku</option>
<option>---- anakku</option>
<option>--- adik ku</option>
<option>-- paman</option>
<option>--- keponakan</option>
谢谢

一个简单的递归应该这样做
public function createTree($arrData, $level = 0)
{
$level ++;
foreach($arrData AS $obj)
{
echo '<option>'.str_repeat('-', $level).$obj->ki_name.'</option>';
if (isset($obj->children) && is_array($obj->children))
{
$this->createTree($obj->children, $level);
}
}
}
