);

//先按path排序，如果数据库取得时已经按path排序则可不进行这一步
foreach ($data as $row) {
    $volume[] = $row['path'];
}
/*
  *预留这里对$volume 进行自定义排序 使用uasort，否则当前只能对id<100评
论有效，当然也可以通过在前面继续加0
  *如000将对<1000以内有效。0000则<10000诸如此类
  *待解决
  */
array_multisort($volume, SORT_ASC, $data);

#01,03,11应排在01,03,05之后，01,07之前
$newData = array();
foreach ($data as &$v) {
    $split = explode(',', $v['path']);
    $i = $split[0];
    $level = count($split)-1;
    $v['lv'] = $level;
    $newData[$i][] = $v;
