I dunno what the documentation is trying to say when it says "list only
works with numerical indices" but it's patently false:
php -a
<?php
$foo = array('a'=>'apple', 'b'=>'banana', 'c'=>'coconut');
while (list($k, $v) = each($foo)){
echo "$k: $v\n";
}
?>
Content-type: text/html
X-Powered-By: PHP/4.3.11
a: apple
b: banana
c: coconut
It has worked just fine with alpha indices since PHP 3.0rc2, at a minimum,
cuz I've been doing it that long.
I dunno who was smoking what that day they typed the documentation :-)
I'm pretty sure it's not an "undocumented feature" that it works.

Richard, this is what the docs are talking about:
list($a,$b,$c,$d) = array('a','b','c','d');
echo $a,$b,$c,$d;
vs.
list($a,$b,$c,$d) = array('a'=>'a','b'=>'b','c'=>'c','d'=>'d');
echo $a,$b,$c,$d;
In your case you are calling each() which itself returns a numerically
indexed array.

Ok, that was not the really right answer ;) Of course it does work.
You can even do stuff on that element, if you use the variable, resp.
reference ($oMyElement) for doing this.
What doesn't work (and I referred to that) is getting this object
back from the DomDocument, so for example:
$oDom->documentElement will give you the DomElement back and not your
new MyElement.
Hope it's a little bit clearer now

You mean that dom methods for retrieving Elements will only return
objects with the object methods defined in the DomElement class?
Is there any way to extend Elements in the tree with own methods? Or is
the dom structurue only used to handle defined methods?
The method DomDocument::CreateElement() only returns instances of
DomElement so maybee the Dom structure is not meant to be extended
regarding elements?

Hi, is this possible--

I'm about to start writing a big web app (mostly in PHP). But I'm not
sure if I should layout the DB first then write the app, or should I
just start writing the app and add stuff to the DB as I need it. How do
you guys go about it?
Thanks,
Dan.
