phpcms v9如何通過欄目catid獲得此欄目下的最新文章的content內容，今天分享一下，寫好的代碼記得收藏哦。

public function show_cntent($catid)

{

$siteids = getcache('category_content', 'commons');

$MODEL = getcache('model', 'commons');

$siteid = $siteids[$catid];

$CATEGORYS = getcache('category_content_'.$siteid, 'commons');

$category = $CATEGORYS[$catid];

$modelid = $category['modelid'];

$this->db->set_model($modelid);

$cid=$this->db->select(array('catid'=>$catid),'id,thumb',1,'inputtime DESC');

$this->db->table_name = $this->db->table_name.'_data';

$con=$this->db->get_one(array('id'=>$cid[0]['id']),'content');

$arr[0]['content']=$con['content'];

$arr[0]['thumb']=$cid[0]['thumb'];

return $arr;

}
