使用laravel 5将多维数组保存为mysql中的行

Question

我有一个来自如下形式的多维数组：

  $items =  array:8 [▼
  "units" => array:4 [▼
    0 => "1"
    1 => "1"
    2 => "1"
    3 => "1"
  ]
  "article_group" => array:4 [▼
    0 => "2401"
    1 => "2503"
    2 => "1360"
    3 => "1198"
  ]
  "article" => array:4 [▶]
  "description_en" => array:4 [▶]
  "unit_price" => array:4 [▶]
  "discount" => array:4 [▶]
  "invoice" => array:4 [▶]
  "delivery_note" => array:4 [▶]
]

表单是动态生成的，不会总是包含 4 个值，但它们总是会包含相同数量的值。

我想要做的是将这些记录保存在这样的mysql数据库中：

$bookingDetails = new bookingDetails;
$bookingDetails->units = units[0];
$bookingDetails->article_group = article_group[0];
$bookingDetails->article = article[0];
$bookingDetails->description_en = description_en[0];
$bookingDetails->unit_price = unit_price[0];
...
$bookingDetails->save();

and then the same thing with [1] and [2] and so on.

但是我如何以这种方式迭代呢？

Answer 1

而不是点击数据库 n 次，在您的情况下，count 次，您可以在 ONE HIT 中使用批量插入。

$your_data = array( array('col_name_1'=>'Value 1', 'col_name_2'=>'Value 2'), array('col_name_1'=>'Value 3', 'col_name_2'=>'Value 4') ); your_model_name::insert($your_data);

这将改善您的应用程序的响应时间。

只需将for 或foreach 循环设为

for($i=0;$i<count($items['units']);$i++){
   $bookingDetails->units = $items['units'][$i];
   $bookingDetails->article_group = $items['article_group'][$i];
   $bookingDetails->article = $items['article'][$i];
   $bookingDetails->description_en = $items['description_en'][$i];
   $bookingDetails->unit_price = $items['unit_price'][$i];
   $bookingDetails->save();
}
