message to the client browser causing it to pop up a Username/Password input window.

Once the user has filled in a username and a password, the URL containing the PHP script will be called again with the predefined variables Note: Compatibility Note Please be careful when coding the HTTP header lines.

IMHO, I suggest you not to use setlocale before having your authentication completed...

HTTP_AUTHORIZATION=$0Now PHP should automatically declare $_SERVER[PHP_AUTH_*] variables if the client sends the Authorization header.

Be careful using http digest authentication (see above, example 34.2) if you have to use the 'setlocale' function *before* validating response with the 'http_digest_parse' function, because there's a conflict with \w in the pattern of 'preg_match_all' function : In fact, as \w is supposed to be any letter or digit or the underscore character, you must not forgot that this may vary depending on your locale configuration (eg. Due to this different pattern interpretation by the 'preg_match_all' function, the 'http_digest_parse' function will always return a false result if you have modified your locale (I mean if your locale accepts some extended characters, see further information).

In order to guarantee maximum compatibility with all clients, the keyword "Basic" should be written with an uppercase "B", the realm string must be enclosed in double (not single) quotes, and exactly one space should precede the , as done in the above example, you may 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.

First of all don't forget this fragment of code in your .htaccess (it's the only thing you need to make it work with mod_rewrite): First, we decode the base64 encoded string discarding the first 6 characters of "Basic " and then we do a regular validation. You can re-enable this functionality as described at your users will probably be unwilling to do this.

At the end of the script we print the variables to verify it's working. To force a logout with Basic Auth, you can change the Realm out from under them to a different Realm.

I believe that this is the only 100% guaranteed way to get a logout in HTTP Basic Auth, and if it were part of the docs a whole lot of BAD user-contributed comments here could be deleted.

Some servers won't support the HTTP1.0 specification and will give an error 500 (for instance). If no password is entered, script sends 200 Header So the browser remembers no password as a valid password.

does not clear the authentication credentials with a 401 server response, so pressing back and then forward again will open the resource as long as the credential requirements haven't changed.
