fair point & good catch.
Mind, now you've gone and re-inforced my point about us 'mere
mortals'.
;)
I'm assuming 'php-general is the general mailing list.

This should be on php-general by now, but...
Why the inner foreach? According to the stated problem, you *know*
which key you're looking for, so why not go straight for it? So...
function proposed_function($array, $key)
{
$total = 0;
foreach($array as $subarr)
if (isset($subarr[$key]))
$total += $subarr[$key];
return $total;
}

You see, if someone with a php.net e-mail addy get's it wrong, what
hope do us 'mere-mortals' have?!?!?! hehe

sorry, i can't code in C/++, so can't do it myself. :)
however that code can't work (i just tested it to make sure).
You missed a layer of the looping.
It should be:
$total = 0;
foreach($array_to_manipulate as $boxes => $box_arrays){
foreach($box_arrays as $key=> $value){
if ($key == 'height') {
$total += $value;
}
}
}
That should work.....
As you can see, with sizeable arrays, it could go around quite a few
times... Which (from a performance front) would be better if it was
done in c(++).... Hint Hint... ;)

Perhaps someone else will be motivated enough to implement this (feel
free to write it yourself and submit a patch to
[EMAIL PROTECTED]) but here's some userspace code which
accomplishes what you want.
$total = 0;
foreach($array_to_manipulate as $key => $value)
if ($key == 'height')
$total += $value;
Which I'm sure you can see is easy enough to wrap in a function.
