本文实例讲述了PHP中基本HTTP认证技巧。分享给大家供大家参考。具体分析如下:

通过组合.htaccess文件和.htpasswd文件被用来阻止用户访问某些服务器上的目录。这些文件包含有关用户被允许访问一个目录和自己的密码信息。 HTTP身份验证可以通过发送特殊的HTTP header信息,而不用使用.htaccess文件

代码如下:

    if (!isset($_SERVER['PHP_AUTH_USER'])) {
        header("WWW-Authenticate: Basic realm=\"My Private Area\"");
        header("HTTP/1.0 401 Unauthorized");
        print "You need valid credentials to get access!\n";
        exit;
    } else {
        if (($_SERVER['PHP_AUTH_USER'] == 'mani') && ($_SERVER['PHP_AUTH_PW'] == 'w#m3nt0r')) {
            print "Welcome to the private area!";
        } else {
            header("WWW-Authenticate: Basic realm=\"My Private Area\"");
            header("HTTP/1.0 401 Unauthorized");
            print "You need valid credentials to get access!\n";
            exit;
        }
    }
?>
