Why is not all data coming?

Question

PHP

Hey!
Post requests are sent from the client to the server and they are quite large (there is a lot of data in the plan, but not the size).

With Ajax, I send only the id , and data parameters , but the last one is a heavily nested array containing other arrays.
In general, there are more than 1000 elements, and this is where the problem begins - for some reason, the id stopped coming to the server .
I look in the console - it is sent, on the server it is equal to null. And all this, as it turned out, is due to the length of the array, because if it is reduced, then the id parameter comes. The array looks something like this:$_POST['id']

data[0][id]=1
data[0][name]=Название
data[0][deleted]=false
data[0][collapsed]=true
data[0][messages][0][replies][0][body]=Сообщение
data[0][messages][0][replies][0][title]=false
...

And an even bigger problem is that, just like the id parameter , all elements of the array, except for index 0, stopped coming.

That is, A with index 1 is narrower . How can this happen? The size of POST requests (such small ones) is essentially unlimited. Could it be related to Nginx settings? var_dump($_POST['data'][0]); // возвращает данные
var_dump($_POST['data'][1]); // null

Answer 1

Try increasing the max_input_vars setting in php.ini to 10000 or more.

Answer 2

Try to send your data partially, split the array into 2-4 parts, and send in batches. as already mentioned above, there may be restrictions, and I think they are there for a reason.

Answer 3

In php.ini parameter max_input_nesting_level. It just for nesting depth also answers.
