- Native array is the best data structure for lists, and outperforms the other methods in both time complexity and overall resource usage.
- SplFixedArray is simply unnecessary. It has no real value over array.
- DataStructures extension was once a great improvement for php7, but not so much anymore, at least for simple lists. Certain data structure manipulations can be still more efficient with php-ds.
