htaccess的文件是Apache服务器下面的一个配置文件，主要负责相关目录下的网页配置，比如我们可以通过htaccess的文件实现，网页301重定向、自定义错误页、改变文件扩展名、php伪静态，目录权限的访问，配置默认文档等。

下面是一个用来操作Apache的.htaccess文件的类，大家可以了解一下即可，其实在Apache服务器下面会自动生成一个htaccess配置文件，如果有需要，可以直接进行更改。

htaccess.class.php 这个是类文件。

examples.php 这个是调用的实例。

[code lang="php"]
setFPasswd("/var/www/htpasswd");

// Setting up path of password file
$ht->setFHtaccess("/var/www/.htaccess");

// Adding user
$ht->addUser("username","0815");

// Changing password for User
$ht->setPasswd("username","newPassword");

// Deleting user
$ht->delUser("username");

// Setting authenification type
// If you don't set, the default type will be "Basic"
$ht->setAuthType("Basic");

// Setting authenification area name
// If you don't set, the default name will be "Internal Area"
$ht->setAuthName("My private Area");

//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
// finally you have to process addLogin()
// to write out the .htaccess file
$ht->addLogin();

// To delete a Login use the delLogin function
$ht->delLogin();
?>
