yes there is difference in creation returning array.. but i talk about other
thing
IMHO
1. "return" returns COPY of array in both cases .. no difference is it
method or function
2. here we don't return reference to the same array.
3. foreach - as i have read in most sources Makes a copy of given array. so
it is 2-nd time i have to get copy of that array so 2-nd foreach dont have
to affect 1-st ...
if the cursor pointing to the same array how can it transparently point
through the method ?
isn't it ?? please correct me if i wrong..
