Would this do the job?

function array_sanitize($array,$filterName)
{
   return array_diff($array,array_filter($array,$filterName));
}

Seems to work in my testing:

$a = array('a'=>6,'b'=>1,'c'=>4,'d'=>9);
$isOdd = create_function('$arg','return $arg % 2 == 1;');
print_r(array_sanitize($a, $isOdd));
