php模块设计。。。里面的模块很有学习价值

<?
	include("db_conn.php");
	include("db_func.php");

	// 查询注册账号名称是否包含不雅字词 BEGIN
	$SQLStr = "SELECT * FROM nogood WHERE n_name LIKE '%$username%'";
	$res = db_query($SQLStr);
	// 查询注册账号名称是否包含不雅字词 END

	if (db_num_rows($res)>0) // 若查询数据有相符
	{
		echo "<script>";
		echo "alert(\"请勿使用不雅名称" . $username . "为账号\");";
		echo "location.href = \"registry1.php\";";
		echo "</script>";
	}
?>
