关于Apache的basic验证

[hohidl]

想问一下，如何开启apache下的basic功能，具体要怎么做啊？我在程序中写了如下代码

if (!isset($PHP_AUTH_USER) || (!isset($PHP_AUTH_PW)))
			{				
				echo "<script language='JavaScript'>alert ('验证失败！请重新登陆。');</script>";
				header("WWW-Authenticate:Basic realm='admin'");
				header('HTTP/1.0 401 Unauthorized');
				exit;
			}
			
			elseif ((isset($PHP_AUTH_USER)) && (isset($PHP_AUTH_PW)))
			{	
			//	echo "<script language='JavaScript'>alert('asd');</script>";
			//	echo "<script language='JavaScript'>alert($PHP_AUTH_USER);</script>";
			//	echo "<script language='JavaScript'>alert($PHP_AUTH_PW);</script>";
				if (($PHP_AUTH_USER != "admin") || ($PHP_AUTH_PW !="admin"))
				{
					header ('WWW-Authenticate: Basic realm="My Private Stuff"');
					header ('HTTP/1.0 401 Unauthorized');
					echo 'Authorization Required.';
					echo "<scritp language='JavaScript'>alert('ok');</script>";
				}
				else if (($PHP_AUTH_USER == "admin") && ($PHP_AUTH_PW == "admin"))
				{
					echo "<script language='JavaScript'>alert ('验证成功！');</script>";
					exit;
				}
			}

同时在apache的配置目录下也去掉了LoadModule auth_basic_module modules/mod_auth_basic.so这一项前的#号，可还是不行，还请各位指点一下！
