Description:
------------
The SplFixedArray implementation doesn't have a __set_state() function, and as such var_export() creates code which does not function. 

Test script:
---------------
var_export(SplFixedArray::fromArray([1,2,3]));



Expected result:
----------------
The SplFixedArray can be exported and the code functions correctly.

Actual result:
--------------
Syntax error in exported code.

@carusogabriel34: The code generation works, but running the code doesn't, as SplFixedArray does not implement __set_state(): https://3v4l.org/50QD3

I'm trying to implement this for Hacktoberfest.

Here's an example that shows existing serialization/unserialization is not quite correct:

My plan to fix this is to have string keys become properties and for numeric keys to become array values. This same design should work for __set_state.

I wasn't able to complete it in the time I allotted. I hope dynamic properties will probably be forbidden on this class at some point in the future, which will help alleviate if not totally fix the issue.
