Bug description: HTTP digest auth example: incorrect regexp
Description:
------------
In the Digest Authentication example on this page:
<http://ca3.php.net/manual/en/features.http-auth.php>
The regular expression used for splitting the auth header is missing at
least one character. The script will fail if a url contains a question
mark '?'. A fix is to change the preg_match_all line to be:
preg_match_all('@(\w+)=(['"]?)([a-zA-Z0-9?=./\_-]+)\2@', $txt, $matches,
PREG_SET_ORDER);
Reproduce code:
---------------
see <http://ca3.php.net/manual/en/features.http-auth.php>, digest auth
example. copy & paste that code into a new file, then try to reach it with
something like (example URL):
http://<your web server>/<file>.php?some=parameter
Expected result:
----------------
I expect the example URL above to authenticate as usual.
Actual result:
--------------
It will never authenticate, because the http_digest_parse() function
returns false after failing to catch the "uri" parameter from the browser
response.
