Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
You've made modifications to the example code so this isn't the right place to get help
with it.
But I will tell you that you're (at least) missing some {}s with the "analyze the
PHP_AUTH_DIGEST variable" check.

Description:
------------
First of the, I use an online web hosting server so can't upgrade anything. PHP 5.3
When using Example 2 in the HTTP authentication with PHP article
it works first, but when wrong creditnals is neter, it will be wrong forever.
Which makes the user not able to login.
Test script:
---------------
$realm = "Hurra 2";
//user => password
$users = array('tcx' => 'yesmrsir');
if (empty($_SERVER['PHP_AUTH_DIGEST'])) {
header('WWW-Authenticate: Digest realm="'.$realm.
'",qop="auth",nonce="'.uniqid().'",opaque="'.md5($realm).'"');
header($_SERVER["SERVER_PROTOCOL"].' 401 Unauthorized');
$txts='<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML
2.0//EN\"><html><head><title>403
Forbidden</title></head><body>';
$txts.='<h1>Forbidden</h1><p>You don\'t have permission to access
ny.php on this server.</p><hr>';
$txts.='<address>Apache Server at example.com Port
80</address></body></html>';
die($txts);
}
// analyze the PHP_AUTH_DIGEST variable
if (!($data = http_digest_parse($_SERVER['PHP_AUTH_DIGEST'])) ||
!isset($users[$data['username']]))
header('WWW-Authenticate: Digest realm="'.$realm.
'",qop="auth",nonce="'.uniqid().'",opaque="'.md5($realm).'"');
header($_SERVER["SERVER_PROTOCOL"].' 401 Unauthorized');
die('Wrong Credentials!');
var_dump($_SERVER['PHP_AUTH_DIGEST']);
// generate the valid response
$A1 = md5($data['username'] . ':' . $realm . ':' .
$users[$data['username']]);
$A2 = md5($_SERVER['REQUEST_METHOD'].':'.$data['uri']);
$valid_response =
md5($A1.':'.$data['nonce'].':'.$data['nc'].':'.$data['cnonce'].':'.$data['qop'].':'.$A2);
if ($data['response'] != $valid_response)
die('Wrong Credentials!');
// ok, valid username & password
echo 'You are logged in as: ' . $data['username'];
//comment reae change
// function to parse the http auth header
function http_digest_parse($txt)
{
// protect against missing data
$needed_parts = array('nonce'=>1, 'nc'=>1, 'cnonce'=>1,
'qop'=>1, 'username'=>1, 'uri'=>1,
'response'=>1);
$data = array();
preg_match_all('@(\w+)=(?:([\'"])([^$2]+)$2|([^\s,]+))@', $txt, $matches,
PREG_SET_ORDER);
foreach ($matches as $m) {
$data[$m[1]] = $m[3] ? trim($m[3],"\",'") :
trim($m[4],"\",'");
unset($needed_parts[$m[1]]);
}
return $needed_parts ? false : $data;
}
Expected result:
----------------
the user is able to renter creditals and then login.
Actual result:
--------------
the script show
wrong crenditals and not show new login box
