PHP.ini, how are the two limitations of max_input_nesting_level and Max_input_vars understood?

My site has only a layer of variables, similar to/index.php?a=a&b=b, will not appear/index.php?a[a]=aa&a[b]=ab, the number of not more than 2.

But the test is only set to the following to not error:

max_input_nesting_level=2

First of all I think it should be = 1, but only = 2 will not error;

max_input_vars=36

This is even more strange, I do not have so many parameters, why 36 can not be wrong.

The above use limit I have to start from 0 to try out.

Also, do you think it is necessary to set this limit a bit larger in order to prevent users from mistakenly entering the path?
