Feln, Richard, Jim,
Thank you for responding.
I understand now that the problem wasn't with variable scope, but with
my lack of understanding of what array_walk_recursive returns.
Thank you all for your explanations.

The goal is to have every open and close bracket matched, and not have
to worry about what is still open.
This is why I use the bracing style I use in PHP. A cursory glance
of the code will show you where you've forgotten a brace. Syntax
highlighting is also nice.
HTML can trip you up with missing or superfluous tags, but a quick
run through the W3C validator will catch those errors.
Cheers,
Rob.
Rob is exactly right on both counts.
Place braces on their own lines and use the W3C Validator to check
both html and css.
Cheers,
tedd

It's trivial to match using this style since you only need to scan one axis.
That bracing style drives me nuts! But I have no problem scanning a
single axis for the close brace and any statement, be it an if, while,
switch, or something else.
Well the way you do it, drives me nuts :)
Morale of the story, do whatever *you* are most comfortable
with..personally I indent as well, has it's downsides I admit, but
it's what I've done for the last 20 years and I'm comfortable with
it.
Alexis
I agree with Alexis.
Furthermore, I place braces on their own lines AND I do it in all
languages I program in, such as CSS, PHP, JavaScript, and others.

With regard of the count thing, why not let MySQL do the work?
$query = SELECT COUNT(*) AS total FROM 'counties' WHERE name = 'checked' ;
$result = mysql_query($query) or die(mysql_error());
$total = $rowcount['total'];

Re: [PHP] Re: Simplest way of enforcing an array of instances of a specific class but treating the whole thing as an array.
On 24 February 2011 18:28, David Harkness davi...@highgearmedia.com wrote:
If each array will contain a single type of object, but you need many of
these arrays, each containing a different type of object, I recommend
creating a generic instances-of-class array using ArrayObject. You can
enforce the type in append(), offsetSet(), and exchangeArray() and then
check the configured type in methods that want to enforce it.
function drawMap(TypedArray $latLngs=null) {
if ($latLngs !$latLngs.containsOnly('LatLng')) {
throw new InvalidArgumentException('$latLngs must contain only
LatLngs');
}
...
}
I guess since there are only three methods to override it wouldn't be too
painful to create a separate class for each type to get method declaration
type hinting. If you aren't containing too many classes and you pass them
around a lot, it may be worth it since you won't have to test the container
inside the method at all.
function drawMap(LatLngArray $latLngs=null) ...
Looks like someone beat us to it:

That's it and in the direction I was heading.
Thanks David - and liamgraham
