这篇文章主要介绍了PHP获取栏目的所有子级和孙级栏目的ID号的具体实现,需要的朋友可以参考下

 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;  }
