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