How to save Array to MySQL database correctly?

Question

JavaScript

Javascript forms an array of the form

[manufacters] => Array
        (
            [51] => Array
                (
                    [7] => Array
                        (
                            [name] => Производитель 1
                            [id] => 7
                            [model] => 51
                            [count] => 1
                            [date] => 2015-10-23 00:00:00
                        )
                )
        )

where as an index, I use the IDs I need.
When saving an array to a database.. I convert it to JSON

[null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,[null,null,null,null,null,null,null,{"name":"Производитель 1","id":"7","model":"51","count":"0"}]]

Actually the question .. is it possible to somehow avoid ... null,null,null,null,null
... the range of used IDs will be large.. accordingly, the number of null,null,null,null,null... will also be large...

Answer 1

Ugliness! Use not an array, but the simplest and most banal object.

{
   22 : {
         one : "something",
         two : "yet something"
   },
   35 : {
         one : "something",
         two : "yet something"
   }
}

Answer 2

serialize unserialize

Answer 3

I tried the object.. the result is the same..
var manufacter = new Object();
manufacter[ID] = VAL ...
JSON.stringify(manufacter)
maybe I'm doing something wrong?
