  获取分类下面的所有子类方法:

  static function getMenuTree($arrCat, $parent_id = 0, $level = 0,$all=True)

  {

  static  $arrTree; //使用static代替global

  if(!$all) $arrTree ='';

  if( empty($arrCat)) return FALSE;

  $level++;

  if($level == 1) $arrTree[] = $parent_id;

  foreach($arrCat as $key => $value)

  {

  if($value['parent_cid' ] == $parent_id)

  {

  //$value[ 'level'] = $level;

  $arrTree[] = $value['cid'];

  unset($arrCat[$key]); //注销当前节点数据,减少已无用的遍历

  self::getMenuTree($arrCat, $value[ 'cid'], $level);

  }

  }

  return $arrTree;

  }

  用上面这个方法的前提是要把分类写到缓存文件中,缓存文件写入方法如下:

  public function actionIndex2()

  {

  $filepath = Yii::getPathOfAlias('application')。'/data/';

  $arr = array();

  $db = Yii::app()->db;

  $listinfo = $db->createCommand("select name,cid,parent_cid,root_cid from item_cat_info")->queryAll();

  foreach($listinfo as $val)

  {

  $arr[$val['cid']] = array('cid'=>$val['cid'],'name'=>$val['name'],'parent_cid'=>$val['parent_cid'],'root_cid'=>$val['root_cid']);

  }

  $applist = "";

  file_put_contents($filepath.'itemcat.php', $applist);

  }
