PHP获取栏目的所有子级和孙级栏目的ID号示例

复制代码 代码如下:
//@获取子栏目ID号
private function sonCategoryIds($categoryID)
{
//@初始化栏目数组
$array[] = $categoryID; do
{
$ids = "";
$temp = $this->mysql->select("SELECT `id` FROM `pcb_article_category` WHERE `parentID` IN (" . $categoryID . ")");
foreach ($temp as $v)
{
$array[] = $v["id"];
$ids .= "," . $v["id"];
}
$ids = substr($ids, 1, strlen($ids));
$categoryID = $ids;
}
while (!empty($temp)); $ids = implode(",", $array); return $ids;
}
