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.

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 {$_SERVER['PHP_AUTH_PW']} as your password.</p>";
}
It would be better to show a message like "Enter your ID and Password" above the user input fields.
<?php
if (!isset($_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>";
}
?>
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.
Doc : https://developer.mozilla.org/en-US/docs/Web/HTTP/Basic_access_authentication
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.
When I log into my router's firmware, for example, I get a prompt box for the username and password, How is this done? As far as I can tell, JavaScript's prompt() only returns one value.. I know it must be server side because the page continues to "load" until I close the box. I also cannot switch tabs in my browser until the box is closed.
Is it possible to do something like this with PHP? How is this done?
Thanks in advance
its done using Basic HTTP Authentication, for this you need to create a user/password file and tell the server that a folder needs to use the Basic HTTP Authentication. This can be done in the server config or in a .htaccess
Take a look at this page of the PHP docs - HTTP authentication with PHP
Here is the sample code that they give:
<?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>";
}
?>
Basically, all you need to do is send the correct headers and the client's browser will be in charge of rendering a native popup with the correct fields.
Once the user has submitted the details your code can validate the login however you want using the $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'] variables.
With Apache as a web server, you could do that with htaccess password protection
The protocol is called http basic authentication
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>";
}
?>
http://php.net/manual/en/features.http-auth.php
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.
