note Ri-Del <P>Alright, I also expected a return of 1,2,3,4, and 5 as the values printed out. However, I think I have learned where I went wrong. I just wanted to make sure I understood the last paragraph of HOW THE CODE WORKS.</P> <P>If I understand this correctly, the <CODE>$each</CODE> variable actually acts as a reference to the current place in the array that the <CODE>foreach</CODE> loop is currently at. So in effect we are actually altering the first array with the <CODE>$each *= 2;</CODE> and then simply setting the <CODE>$i</CODE> place in the <CODE>@newlist</CODE> to be the same value. This is the reason why we are subtracting, in the last loop, the exact same values from each other.</P> 72605 72634
