But again that modifies the array (it advances the cursor).Not really. 
It does not modify the keys or the values.  The cursor is a variable
used to determine which key and value is returned on the next call to
each().If you absolutely must have the state exactly the same before and
after, then add a call to reset() to your code, it is mentioned in that page
in the manual. >  > I guess I can write something myself: >  >
