thanks for the reply... just happened to see
which explains the above result

i want to explicitly type cast all the numbers passed via post (by
default they are strings)
is_numeric() is a option, but it will not be possible to differentiate
between int and float.

$_POST['month'] !== (string)(int)$_POST['month']
this is exactly what i want... but wont this take up memory when used
with array_walk_recursive() ?
