復制代碼 代碼如下:
//@獲取子欄目ID號
private function sonCategoryIds($categoryID)
{
//@初始化欄目數組
$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;
}
