Indeed, whilst your method is simplistic it leaves many copies of the array
dangling in memory. Every time you call foreach it creates a copy of the
array internally. SPL iterators do things differently and know only one
element at a time. More can be seen at
http://phpro.org/tutorials/Introduction-to-SPL.html
so the final solution was using a foreach, however, using a foreach on an
SPL iterator object implicitly calls the inner iterator giving us all the
SPL goodness in memory savings.
Kind regards
