a) foreach works on the prospected copy of the original array.
It means foreach() will have SHARED data storage until or unless a prospected copy is
not created foreach Notes/User comments .
b) What triggers a prospected copy?
A prospected copy is created based on the policy of copy-on-write, that is, whenever
an array passed to foreach() is changed, a clone of the original array is created.
c) The original array and foreach() iterator will have DISTINCT SENTINEL VARIABLES, that is, one for the original array and other for foreach; see the test code below. SPL , Iterators , and Array Iterator .
