You have many instances where you're accessing the array using curly braces.

Fix: Replace the {} with [] when you're accessing array elements.

Thanks for pointing out, i'll leave this open to check for more occurrences tomorrow when at work.
If you find anything else, let me know.

I think this has been taken care of in 1.0.7. We added phpstan for checking and also started adding tests, hopefully will catch such things in future.
