This should work. This function recursively goes through a given array
and adds up the sizes.
Note that I had to use regex to get the numerical size as you have
this string, '->' , in there.

function getSize($map) {
$size = 0;
foreach($map as $m) {
if(!is_array($m)) {
preg_match("/[0-9]{1,20}/", $m, $p); // regex to get the size
$size += $p[0];
} else {
$size += getsize($m);
}
}
return $size;
}

$structure = mapit();
echo getsize($structure['dirs']['upload']);

Thank you very much for your quick help!
Not to be a nag though, but if i store other numerical values in the
array (like filemtime), wouldn't they be counted as well?

Would it be better to give each file a ['size'] key? In the best case,
i thought, it would be best to somehow perform the count at the same
time as doing the first loop, so you wouldn't have to run unnecessary
loop, or am i wrong?

Thanks a lot again though!!

(The '->' part doesn't have to be there, it was merely a visual
"guide" for me ...)

Yes, extra keys would cause the function not to work.
Like you said, a 'size' key would get rid of all the confusion. If you
get it there, simply get rid of the regex line and add the value of
the 'size' key to $size.

Great, thanks a lot! I'll probably sadly enough won't have any time
before tomorrow to take a look at it, but i'm confident i can get it
to work! :)

And my remark of doing the counting loop at the same time as the
initial loop, or is that peanuts (in calculating power/speed) for PHP?

Thanks again for helping me so far!
