can somebody point me to a good article or a piece of code on
implementing an iterator for a mysql result resource?
actually this is for an oracle statement handle, all i want is to
fetch the results as it is from a multi dimensional array. so i can
use it in a for each with keys
IteratorAggregate over Iterator seems the best fit for the task as i
do not want seeking back and forth.
thanks!

On line 20, $url creates an URL path that includes the $cat path. Once
you've completed iteration on all children of $cat, the url path should no
longer include $cat path, thus it is removed from $urlStack.

Line 29 is closing the li element that was opened on line 23 for $cat.

I have two questions about this code, that hopefully someone on the list
could explain:
1)
Why do we need to remove the last array item? (on line 32):
array_pop($urlStack);
On line 20, $url creates an URL path that includes the $cat path. Once you've
completed iteration on all children of $cat, the url path should no longer
include $cat path, thus it is removed from $urlStack.
2)
Why we print the closed tag of the li element, after the recursive call? (on
line 29)
echo "</li>\n";
Line 29 is closing the li element that was opened on line 23 for $cat.
Thanks a lot in advance,

Thanks a lot. I knew that:
“Line 29 is closing the li element that was opened on line 23 for $cat.”
My question intend to be more like:
Why that line to close the li element is *after* the recursive call?
Somehow, it seems that instead of creating something like this:
<ul>
<li>item1</li>
<li>item2</li>
<li>item3</li>
</ul>
We are doing:
<ul>
<li>item1
<li>item2
<li>item3
</li>
</ul>
Anyway, the main doubt was the first. I will test this and see what I get.
Thanks a lot for your reply.
Regards,
Márcio

Hello,
Is it possible to get a list (array) of classes not found in a script
before the fatal error exits the parser. I realize that PHP parses the
script twice. It would be nice at the end of the first parsing pass to
check to see which classes haven't been defined (yet), so that I could
define them before the second pass. This way I could load only those
classes a script needs.
Thanks in advance,
dK
