saving multidimensional array as rows in mysql using laravel 5 - php

Question

i have a multidimensional array from a form that looks like this:
$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 [▶]
]
The form is dynamically generated, and will not always contain 4 values, but they will always contain the same amount of values.
What i want to do is to save these records in a mysql database like this:
$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.
but how do i iterate through this in that way?

Answer 1

Rather than hitting the database n number of times, in your case, count times, you can do the same in ONE HIT using bulk insert.
$your_data = array(
array('col_name_1'=>'Value 1', 'col_name_2'=>'Value 2'),
array('col_name_1'=>'Value 3', 'col_name_2'=>'Value 4')
);
your_model_name::insert($your_data);
This will improve the response time of your application.

Answer 2

Simply make a for or foreach loop as
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();
}
