PHP warnings

Hi all --

My site seems to be running fine, with no apparent or reported errors.

But I happened to check my error log, and found the following messages:

[Fri Jun 2 17:09:02 2006] [error] PHP Warning: Division by zero in /home/evesteve/public_html/zen-cart/includes/classes/split_page_results.php on line 76
[Fri Jun 2 17:09:01 2006] [error] PHP Warning: Division by zero in /home/evesteve/public_html/zen-cart/includes/classes/split_page_results.php on line 76
[Fri Jun 2 17:08:44 2006] [error] PHP Warning: Variable passed to each() is not an array or object in /home/evesteve/public_html/zen-cart/includes/classes/shopping_cart.php on line 1658
[Fri Jun 2 17:08:24 2006] [error] PHP Warning: Variable passed to each() is not an array or object in /home/evesteve/public_html/zen-cart/includes/classes/shopping_cart.php on line 1658
The first error seems to refer to the line:

$this->number_of_pages = ceil($this->number_of_rows / $this->number_of_rows_per_page);

where, apparently, 'number_of_rows_per_page' is not getting properly set higher up in the page (it's not referenced in any other file in the site).

The other error refers to the line:

while ( list( $key, $val ) = each($_POST['products_id']) ) {

... which I'm at a loss to interpret; it's all geek to me.

As stated, though, the site seems to be working. Any ideas what's going on?

[edit: spelling & tense correction]

What version of Zen Cart are you running?

will keep this in mind during next round of testing related to system internals. But at present, I can't duplicate this. I'm inclined to think it's related to certain data in your database, but unable to pinpoint just what, since those portions of the code are triggered by various other sources, and never run on their own directly..... it could be coming from any number of places.

Well, apparently I can't duplicate it either -- at least, there are no more PHP warnings since those. So if there is a bug somewhere, either in the code or in my set-up, it seems to be rare.

I'll keep an eye out & see if either happens again. If so, I'll gather as much detail as I can & re-post.

Thanks for your help! Like I said, the cart seems to be running fine in any case.
