This is one example where references actually decrease memory usage.
The main reason is the recursive nature of the function. Try
?php
echo memory_get_usage() . PHP_EOL;
$array = range(0,100);
$array[10] = range(0,10);
$array[20] = range(0,10);
$array[30] = range(0,10);
$array[40] =

BTW, it's not the recursive nature of the function causing the problem.
It's the movement of the internal pointer within the array. When it
Hmm, will probably have to look inside PHP for this ... the foreach
loop will copy each element as it loops over it (without actually
copying, obviously), however there's no change happening to the
element at any point and so there's nothing to suggest to the
copy-on-write to create a new instance

Anyone have a function that will return an integer of the number of

I did some quick searches and came up with nothing.
The closest was here of someone asking the same thing, but his solution
isn't right:

Oh. I know it's not a simple solution to do right Ashley. And exacerbated
by the fact that each array dimension can have different dimensions as
well. This is why I wanted someone else's solution first before I spend
hours or days on one that works reliably. :)
