I got this code from php.net
is it possible to set target folder(or URL), userID and password?
I don't want to show popup login window to user
for example)
after line of header('HTTP/1.0 401 Unauthorized');
header('URL:./target_folder/')
header('UserID:guest')
header('Password:guest')
I'm not sure about what you want, but you can pass your username and password in the URL like this :
https://username:password#www.example.com/path
It will not display any login popup.

Be aware of the Security section
The BA mechanism provides no confidentiality protection for the transmitted credentials. They are merely encoded with BASE64 in transit, but not encrypted or hashed in any way. Basic Authentication is, therefore, typically used over HTTPS.

I've create a basic authenticated page with php and set WWW-Authenticated: Basic realm="My Realm" header.
I've expected the message "My Realm" would be seen above the user input fields but only URL shows up as default setting.
I want have browsers to show a descent message on a specific page for users with IOS.
Though it is not secure at all but it's ok for now.
Usually I use apache on linux but this time, IIS on Windows2012R2 and it's private network.I thought php is reasonable to make authentication to work with one specific page.
setting charset="UTF-8" to header and
changing the realm word have no effect and I can't get any clues on search engine.
I've copied the following code from php.net as instruction for basic authentication , actual function works but only "My Realm" message is missing.
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>";
}
It would be better to show a message like "Enter your ID and Password" above the user input fields.
I need to set up HTTP authentication. I'm lost, I've researched and found the technique and code to validate $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'], and I think I understand that. However I don't understand how to set PHP_AUTH_USER and PHP_AUTH_PW ? I used print-r on $_SERVER and didn't see either? Do I somehow set these in a file somewhere on the server, or do I set using code?
I'm on a shared server hosted by Webfaction.
I realize this might not be a great question, but if someone would point me in the right direction it would be great..
<?php
if (!isset($_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>";
}
When the page is called, $_SERVER['PHP_AUTH_USER'] is not set. So the page return header HTTP/1.0 401 Unauthorized that show the modal on your browser.
And when the browser send se second request with ID and password. It send this request:
Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
And the super global vars PHP_AUTH_USER and PHP_AUTH_PW are automaticaly setted by PHP.
Sources:
http://en.wikipedia.org/wiki/Basic_access_authentication
http://php.net/manual/en/features.http-auth.php
Here's all the code you need:
$successful = FALSE;
if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
{
$username = $_SERVER['PHP_AUTH_USER'];
$password = $_SERVER['PHP_AUTH_PW'];
if ($username == '-- username --' && $password == '-- password --')
{
$successful = TRUE;
}
}
if ( ! $successful)
{
header('WWW-Authenticate: Basic realm="Secret page"');
header('HTTP/1.0 401 Unauthorized');
}
It would ask for username and password, see if they match and if they don't - ask for them again.
Note that, depending on server configuration, HTTP Basic Authentication may not work.
p.s. You should replace -- username -- and -- password -- with username and password of your own.
To set an environment variable (aka superglobals), the format is:
$_SERVER['variable'] = value (or variable);
http://php.net/manual/en/language.variables.superglobals.php - good info on PHP superglobal variables.
We have a new b2b vendor that wants to use basic auth via URL.
They want to authenticate like this:
//URL coming into our server
http://usernametext:passwordtext#our.company.com/listener.php
How can I get the username and password from the URL via my listener.php script?
I have tried setting basic auth headers per the php man page but it pops up a login box, which is not what I need, since these are web services talking to each other, not people:
if (!isset($_SERVER['PHP_AUTH_USER'])) {
header('WWW-Authenticate: Basic realm="My Realm"');
header('HTTP/1.0 401 Unauthorized');
echo '<response><error>No username and password found</error></response>';
exit;
} else {
//process request if username & password are legit
}
Thanks to all that offered solutions. Here is what solved this issue for me:
It was a server configuration issue. I needed to compile the Apache extension in my PHP. Once I did that, the $_SERVER array contained $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'] values. Prior to this, those values were missing from the $_SERVER array
Why not send the info via good old $_GET? Something like
http://our.company.com/listener.php?usr='me'&pswd='secret'
may be this could help:
if (!isset($_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>";
}
more detailed you can check on : http-auth
Update: If you dont need popup box (which is confirmation user+pass on non required auth site) simply add .htaccess on directory.
AuthType Basic
AuthName "Password Required"
Try the following URL: https://cms1.gre.ac.uk/collaborativeprogrammes/student/index.asp
It brings up an authentication prompt with username and password which is separate from the accounts on their site; groups of users have the same username and password to gain entry, however once inside, you log in with you own username and password.
How could I implement this? i.e. the first authentication prompt only.
If you're hosting on windows then turn on windows authentication in IIS.
Your users would need their Active Directory credentials to log on.

You can read this article on HTTP Authentication in PHP
See http://php.net/manual/en/features.http-auth.php
<?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>";
}
?>
Although this is an asp page, you can do this in php with .htaccess file
See this article:

how to create user authentication in php just the same way when we try to login to a router.
when i enter the url for example www.example.com/portal there should be a prompt like the above image asking username and password.
what type of authentication is this. how to code that in php.
NOTE: i have to full control of the server that i run. so is there any special module that needs to be installed i can do that.
This is called Basic Auth. See this example from the documentation:
<?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>";
}
?>

Essentially, you send the right headers with the status code of 401 Unauthorized. the browser sees this along with your WWW-Authenticate header and prompts the user for you. Once this is done, you are able to see the username and password in $_SERVER['PHP_AUTH_USER'] as well as $_SERVER['PHP_AUTH_PW'].
You should know though that if you are using basic auth, the username/password are sent plaint-text. You must use HTTPS if you want any sort of security. Also, depending on your application, you will see that there is no way to effectively "log out". Most browsers remember the username/password for the entire session, and send it with every subsequent request.
This is basic http authentification. You could find a tutorial on the php.net page: http://www.php.net/manual/en/features.http-auth.php
It is basically a http header, that you have to send to the browser. The http server (apache/nginx) will forward the userdata afterwards to php like any other $_SERVER parameter.
