使用方法

$passwdHandler = new Htpasswd('/home/myuser/.htpasswd');

// Add a user with name 'user1' and password 'I prefer to use passphrase rather than password.' if it doesn't exist in .htpasswd.

$passwdHandler -> addUser('user1', 'I prefer to use passphrase rather than password.');

// Delete the user 'user1' if it exists in .htpasswd.

$passwdHandler -> deleteUser('user1');

// Check if user 'user1' exists in .htpasswd.

if ($passwdHandler -> doesUserExist('user1')) {

// User 'user1' exists.

}
