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']);
