codeigniter使用技巧批量插入数据实例方法分享

复制代码 代码如下:
$sub_form = array();
  $loop = 0;
  $ins_loop = 0;
  $sum = count($form_datas);
  $this->logger->info("insert data total:".$sum);
  //使用事物批量导入有助于提高插入效率
  $callStartTime = microtime(true);
  $this->db->trans_start();
  foreach ( $form_datas as $item ) {
         $loop ++;
         $sub_form[] = $item;
         if(($loop % 200) == 0 || $loop == $sum){
          $this->logger->info("insert data num:".$loop);
    $res = $this->kb_object_instance_mdl->insert_batch($sub_form,$obj_id);
    $ins_loop ++;
    unset($sub_form);
    if(($ins_loop % 5) == 0){
     $this->logger->info("insert data trans_complete ins_loop:".$ins_loop);
           $this->db->trans_complete();
           if($loop != $sum){
            $this->db->trans_start();
           }
    }
         }
  }
  //$this->db->trans_complete();
  $callEndTime = microtime(true);
  $callTime = $callEndTime - $callStartTime;
  $this->logger->info("insert data use time:".sprintf("%.4f",$callTime));
     if($this->db->trans_status() === TRUE){
      $this->_show_msg("1",array("data"=>"import ok"));
     }else{
      $this->_show_error("saveOrUpdate error");
     }
