duh...he said he has numbers? thus, populate the array and randomize it and
trim it with _rand.. sorry, I thought it was obvious

that is how it works - check for yourself.. duplicates are not removed (if
he has any - and shouldn't if he populates from db..)
if you go through the array with it, keys are not removed - they are simply
reinitialized ..look at your link that you've posted by yourself

yes, indeed it isn't - but that's only if he gets duplicate id's from db (if
I remember correctly - he needs to randomize sequence from db?)...and if he
gets duplicates from this..then magic is what is needed.. some form of
deletion operations
