I think the cleanest way is to not mention them in your INSERT-statement. You could start writing triggers to fill default values but that's heavy armor for what you're aiming at.

Isn't it possible to restructure your application code a bit? In PHP, you could construct a clean INSERT-statement without messy if's, e.g. like this:

 $value) {
  if (is_null($value) || $value=="") {
    unset($insert[$key]);
  }
}

// construct insert statement
$statement = "insert into table (". implode(array_keys($insert), ',') .") values (:". implode(array_keys($insert), ',:') .")";

// call oci_parse
$stid = oci_parse($conn, $statement);

// bind parameters
foreach ($insert as $key => $value) {
  oci_bind_by_name($stid, ":".$key, $value);
}

// execute!
oci_execute($stid);
?>
