Hello,

Originally I was managing the indexes of an internal array I have. But I
ran into issues when calling zend_hash_rehash so I started relying
on nNextFreeElement from HashTable.

If a user gives me 12 as their index they would like to look up, how would
I translate that into the real value needed for nNextFreeElement ?

Basically index_from_user_land != nNextFreeElement

thx
