PHP Objects vs Arrays — Performance comparison while iterating

Question

I have a huge amount of PHP objects for a neural network for which I have to iterate over and perform some maths on. I was wondering if I would be better off using an associ

Answer 1

You can always check the PHP-source code for micro-performance-features like that.

But at a first glance, no doing ['value'] will not be faster because PHP needs to do a Lookup on where to find ['value'] even thougn a hashtable lookup should be O(1), that's not guaranteed. There's more overhead when you use Text-index.

If the object only contains 1 variables that you need to access which is value, there's more overhead in using an object.
