I'd expect that for two reasons.
The first is that all array keys are interred strings (names) so
integers need to first be converted to strings and then hashed into a
name and then hashed to the slot in the arrays hash table.
I thought at some point we had talked about numeric arrarys (as
opposed to hashes) if all the keys were numbers. That's why I filled
the array that way. Is that not the case? Can we put that one to bed?
All arrays are string-keyed currently.
However, the engine treats arrays which have all integer (string) keys
starting at one and are dense (i.e. the number of elements == max(all
keys)) from ones that aren't.
The fact the keys are still strings is an implementation detail really -
although one which does leave room for optimization (see the reply I
wrote about PHP7 - particularly the notion of tagged ptrs for integers).
Warmest Regards,
Mark.
