I think he was making an assumption about PHP based on how other
languages work. Everyone in the class is using Python or Java. He
is letting me use PHP, which hasn't been done before in this class.
Thanks for the tip on objects, I'll keep that in mind.

If your professor was referring to PHP, it's possible he could have been
referring to objects, not arrays. Objects are copied by reference, so if
you do this:
$Item = new Item;
$Item2 = $Item;
$Item2->setProductId('12');
print $Item->getProductId();
Your output will be '12'. If you want to cop
Indeed it does. Sorry! I was led to believe (by my cs professor)
that the default behavior when copying an array is that the copied
array is not a new instance but is tied by pointers to the old array,
so changes to one would change both of them. Other people in the
class are using pytho

That depends on what the array contains. If it contains primitives
(numbers, chars, or booleans), you can just write a loop. If it contains
objects, just

Python has a function called deepcopy:

For Java, it appears you can use a handmade function o
