我有一个由父母和孩子组成的类别数组。有人可以帮助我使用parent_id和category_id与foreach循环在层次结构中排列数组。最顶层的Parent的parent_id为“0”。请忽略除category_id和parent_id之外的其他字段。这是我的阵列。

答案 0 :(得分：0)
考虑功能
function get_childs($arr, $parent_id = 0) {
$res = array();
foreach ($arr as $row) {
if ($parent_id == $row['parent_id']) {
$childs = get_childs($arr, $row['category_id']);
$row['childs'] = $childs;
$res[] = $row;
}
}
return $res;
}
然后使用此功能获取父母及其孩子
$res = get_childs($arr);
