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; }
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']); } $applist = "<?php\nreturn ".var_export($arr, true).";\n?>"; file_put_contents($filepath.'itemcat.php', $applist); }
