Script Name Simple Authentication This is a simple authentication example that uses the HEADER function to force users to authenticate themselves. It works only if PHP is installed as an Apache module. Instead of simply printing out the $PHP_AUTH_USER and $PHP_AUTH_PW, you would probably want to check the username and password for validity. Perhaps by sending a query to a database, or by looking up the user in a dbm file. class::Htpasswd Htgroup This class facilitates the maintenance of htgroup files, used to do Basic Authentication on a web server. This class assumes PHP v3.0 or better and Apache 1.3.3 or better. Htgroup file format should conform to the httpd spec (ie. groupname: user user user user, groupname: user user user user user) A groupname, terminated by a colon, followed by one or more users seperated by spaces, and line terminated with a carriage return. Group files that do not conform to the httpd spec will cause strange things to happen.
