If you mean the internal pointer, ie the one that is reset by calling reset(),
then who cares. Keeping that pointer across pages has little/no value. What
is important is that the structure and values of the array is intact.

AFAICS serialize() on a string seems to be redundant. serialize() is supposed
to represent some complex entity (eg an array) as a string so it can be
easily stored, transmitted etc.
So something like:
$var_to_pass_in_url = urlencode(serialize($Array1));
Then construct your url like so:
http://www.example.com/example.php?Array1=$var_to_pass_in_url
Then in example.php you reconstruct the array:
$Array1 = unserialize($_GET['Array1']);
ought to work (but untested).

RE: [PHP] Passing array variables in a GET
I looked at the page you suggested but it vauge at best. Basically from
what I've gathered using serialize with an array screws up the pointers
in the array. Is this true?
What I've done is this but it doesn't seem to be working...
Pull data (two fields) from a mysql table and put the results into two
arrays, one for each field
Query results for field 1 -> Array1[]
Query results for field 2 -> Array2[]
Then I create a variable with the imploded data from the arrays
$var1=implode(":", $Array1);
$var2=implode(":", $Array2);
Then serialize the variables...
$varSER1=serialize($var1);
$varSER2=serialize($var2);
Then pass the variables in the url via a GET.
It doesn't work however

RE: [PHP] Passing array variables in a GET
Take a look at http://nl.php.net/manual/en/function.serialize.php and http://nl.php.net/manual/en/function.unserialize.php. Or if the keys don't matter and the array has just one level (strange, I know there's a different term for that, totally cannot find it in my memory :S) you can consider join() and split().
