the problem I would have with the above code would be that it assumes
you're using a single dimention array.
Recursive foreach:
function array_size($a){
$size = 0;
while(list($k, $v) = each($a)){
$size += is_array($v) ? array_size($v) : strlen($v);
}
return $size;
}
This could possibly be optimised even more by using references or something
like that.
eg
foreach(array_keys($a) as $k){
size = is_array($a[$k]) =& array_size($a[$k]) : strlen($a[$k])
But I think that for the most part your time programming will be more
important than the programs time running.
