关于一个php数组去重的问题

Question

场景：
需要从excel中导入信息导数据库。要求如下：

1. 同一订单号下，可以存在多条记录

2. 检测“产品”在“使用产品”（在已有数据表中获取）内，方可导入

3. 表中相同交易单号的多个产品，只要有一个产品在“使用产品”内，就全部导入，记成1条。如果一个都没有则不导入

现在我模拟数据如下：

打印出来的导入数组为:

array (size=4)
  '667283818213324' => 
    array (size=17)
      0 => 
        array (size=9)
          0 => string '2017年8月12日23:44:58' (length=24)
          1 => string '李锐钊' (length=9)
          2 => string '满堂红' (length=9)
          3 => string '667283818213324' (length=15)
          4 => string 'ruizhaole112313' (length=15)
          5 => string '十天PHP从入门到放弃' (length=27)
          6 => float 1
          7 => float 2
          8 => string '火星' (length=6)
      1 => 
        array (size=9)
          0 => string '2017年8月12日23:44:59' (length=24)
          1 => string '李锐钊' (length=9)
          2 => string '满堂红' (length=9)

(我的思路是用订单号做key来存放数组，但是下一步中检测多个记录在不在产品表中存在至少一个相同记录不知道该如何写，没有头绪)

            }
            dump($proLists); exit;

摸索了一上午时间，把实际需要的怼了出来，不清楚有没有什么BUG，也没做优化。直接上代码：

    // +-----------------------------------------------
    // | 导入xls至数据库
    // +-----------------------------------------------
    public function importXLS()
    {
        if ($this->request->isPost()) {
            $file = $this->request->param('file', '' ,'trim');
            $file = ROOT_PATH . 'public' . $file;
            if (empty($file)) return $this->error('不能导入空文件');
            if (!file_exists($file)) return $this->error('要导入的文件不存在');
            // 自动判断后缀名是xls 还是 xlsx,两种不同的后缀需要的类不一样
            $extension = strtolower(pathinfo($file, PATHINFO_EXTENSION));
            if ($extension =='xlsx') {
                $objReader = new PHPExcel_Reader_Excel2007();
            } else if ($extension =='xls') {
                $objReader = new PHPExcel_Reader_Excel5();
            }
