How about array_filter()? From the docs: "If the callback function is
not supplied, array_filter() will remove all the entries of input
that are equal to FALSE."
$a = array ('a' => 'foo', 'b' => '', 'c' => null, 'd' => 99, 'e' => 0);
print_r (array_filter ($a));
// Output:
Array
(
[a] => foo
[d] => 99
)
As a previous poster noted, though, this will only work for you if "0"
and the empty string et al. are not significant in your application.
