PHP authentication question?

[mshen]

I try the code but I can not pass through authentication. After I enter the user name and password.the pop-up window appear again and ask user name and password again.the program can not print out "hello ...".

<?php
if (!isset($SERVER['PHP_AUTH_USER'])) {
header('WWW-Authenticate: Basic realm="My Realm"');
header('HTTP/1.0 401 Unauthorized');
echo 'Text to send if user hits Cancel button';
exit;
} else {
echo "<p>Hello {$SERVER['PHP_AUTH_USER']}.</p>";
echo "<p>You entered {$_SERVER['PHP_AUTH_PW']} as your password.</p>";
}
?>

My question is why $_SERVER['PHP_AUTH_USER is always not existed.even if I enter user name and password.

Do I have to change settings?Please help me.

Thanks a lot

$SERVER['PHP_AUTH_USER'] and $SERVER['PHP_AUTH_PW'] will only be available if PHP is running as an Apache module.

I want to know if authentication also works in windows 2000 with apache 2.0

Thanks

According to the Apache documentation (bet you didn't even know it had documentation, did you?) the answer is yes.

do you try it before?
