Hello!
PHP 8.1 supports array unpacking with keys. I guess that is very similar to
array_merge(), but for some reason array_merge() is 50% slower than
unpacking.
So my question is: is there some way to optimize the engine so
array_merge() can work like unpacking?
Thanks!
Hi David,
It would be useful if you could provide your measurements and the way you
arrived at such results. A quick test doesn't seem to support your
findings: https://3v4l.org/v5m9f#v8.1.8
There are already a number of optimizations in array_merge. It might depend
on the actual test data that you used. Maybe a specific path needs to be
optimized. Please provide some more details.

You are right. I do not know how I tested before, but actually,
array_merge() is bit faster than array unpacking.
Atenciosamente,
