缺点：相同数据格式的数值无法叠加，页面数据格式太繁琐，最初下标值为整数的结构会出错假设基础数据字段列表baseRowList格式是 array(array('pid'=>xxxx, 'id'=>xxxx, 'name'=>xxx, 'age'=>xxx), ....)页面数据显示dataStruct格式是array('list'=>array('pid'=> array('id' => array('name', 'age'))),'nameList' => array('id'=>'name')),1. 将dataStruct数组 递归抽取转化为可显示层级结构的字符串如将dataStruct转化为structList = array("list,pid,id,name", "list,pid,id,age", "nameList,id,name")， getStructList函数2. 读取一条基础数据，循环分隔structList，将其中的字串关键字替换为基础数值或者不变3. 重复循环2直至基础数据所有处理完成代码如下：private function getsRowStructData($baseRowList, $dataStruct){$list = array();if($baseRowList){$structList = self::getStructList($dataStruct);$rowKeyArr = self::getRowKeyArr($baseRowList);foreach ($baseRowList as $row){if($structList)foreach ($structList as $struct){$list = $list + self::getOneStructData(explode(',', $struct), $row, $rowKeyArr);}}}return $list;}// 获取 列表关键字下标数组private function getRowKeyArr($list){$arr = NULL;if($list)foreach ($list as $row)if(is_array($row))foreach ($row as $k => $v)$arr[] = $k;return $arr;}// 将层级结构数组中的关键字 替换为实际值，并返回 页面结构数据private function getOneStructData($oneStructList, $dataRow, $rowKeyArr){$row = array();if($oneStructList){for($i=count($oneStructList)-1; $i>=0; $i--){if(in_array($oneStructList[$i], $rowKeyArr)){$row = ($row) ? array($dataRow[$oneStructList[$i]]=>$row) : $dataRow[$oneStructList[$i]] ;}else{$row = ($row) ? array($oneStructList[$i]=>$row) : $oneStructList[$i];}}}return $row;}// 根据页面显示的数据结构返回 层级结构数组private function getStructList($struct, $list=array(), $prefix=NULL){$tmpList = $list;if(is_array($struct)){foreach ($struct as $k => $v){if(is_array($v)){$tmpPrefix = ($prefix) ? "{$prefix},{$k}": $k;$tmpList = self::getStructList($v, $tmpList, $tmpPrefix);}else{$tmpPrefix = ($prefix) ?
