不基于数据库：
<"a" && $strAuthPass == "a")) {
header('WWW-Authenticate: Basic realm="wly"');
header('HTTP/1.0 401 Unauthorized');
echo "用户验证!!";
exit;
} else {
echo "验证通过";
header("location:http://www.baidu.com");
//unset($_SERVER['PHP_AUTH_USER']);
}
"htmlcode">
<"Secret Stash"');
header("HTTP/1.0 401 Unauthorized");
exit;
}
if (! isset($_SERVER['PHP_AUTH_USER'])) {
authenticate_user();
} else {
mysql_pconnect("localhost","authenticator","secret") or die("Can't connect to database server!");
mysql_select_db("java2s") or die("Can't select authentication database!");
$query = "SELECT username, pswd FROM user WHERE username='$_SERVER[PHP_AUTH_USER]' AND pswd=MD5('$_SERVER[PHP_AUTH_PW]')";
$result = mysql_query($query);
// If nothing was found, reprompt the user for the login information.
if (mysql_num_rows($result) == 0) {
authenticate_user();
}
}
?>
