[Editor's Note: PHP almost always passes arguments by value and not by reference. current() is
doing exactly what it seems to be doing - returning a copy of the value stored in the array
element.]
When looping through the contents of an array, current() actually seems to return a "copy"
of each element in that array. Therefore, any changes you make to the value returned by current
won't affect the value referenced by the array item.
