script for including files

<?php

// including required files
require("include/db.inc.php"); // Database configration file
require("include/fun.inc.php"); // functions file
require("include/header.inc.php"); // Header Control
require("include/form.con.php"); // Posted Form Control
require("include/main.actions.php"); // Page Actions
?>

is this include process is alright?
