note 93098 deleted from function.array-search by danbrown

Note Submitter: Photis Patriotis ---- It doesn't seem as though the Binary Search algorithm would really be faster in PHP considering that arrays are stored with keys that are variable as well. So, PHP, internally, has to search through the keys every time $array_name[$key] is referenced anyway. Unless PHP knows implicitly that the keys are all integers and in order, and then it can pull the value via memory location. This would make the binary search algorithms proposed here slower than a natively programmed array search. Does anyone know whether this is a correct assumption?
