Hi!
The bucket can store 2 types of data - either any random piece of data
(ARPD) or a pointer. When bucket with ARPD is created/deleted, the
memory storing ARPD is allocated/freed. When bucket holding a pointer is
created/freed, nothing special happens since the pointer is stored
inside the bucket.
zend_hash_find returns the pointer to the data stored, not the copy of
it (since you might want to modify it), that's the reason why it's
void** - it's pointer to the data, which is by itself either pointer
passed to hash or pointer to allocated piece for ARPD.
