PHP_AUTH_USER not set? | 易学教程

For some reason, none of the code within

if (isset($_SERVER['PHP_AUTH_USER']) &&
    isset($_SERVER['PHP_AUTH_PW']))

{



// When the above is set, the code that is here will execute of course

}

is being executed for me. When I enter the correct username and password, the prompt box for the authorization again pops up. Wouldn't both fields be 'set' if they are correct and I press enter? But for some reason that is not the case. What can I be doing wrong? Thank you.

There is a 'sensible way' to use HTTP Basic Auth in CGI-mode PHP: in the .htaccess use

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

and in the PHP use

list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = 
  explode(':', base64_decode(substr($_SERVER['HTTP_AUTHORIZATION'], 6)));

try this

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
</IfModule>

on your .htaccess file which you will have to place into the root directory

and then

list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':' , base64_decode(substr($_SERVER['HTTP_AUTHORIZATION'], 6)));

in the begining of your php scripts

I am using Symfony 2.5.7 running on PHP-PFM + Apache 2.4 on Ubuntu 14.04. I have BASIC_AUTH working, it needs to correctly configure the Apache VirtualHost by adding:

SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

as also mentioned here https://stackoverflow.com/a/17490827/435956

In my phpinfo() Sever API is CGI/Fast CGI. So I've solved my problem with writing following in my .htaccess file RewriteEngine on RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ app.php [QSA,L]

Try $_SERVER['REMOTE_USER']. This works for me on a PHP 5.3 CGI + Apache installation.

If user access is granted giving username/password in URL please check if

AuthType Digest

is entitled in your VHost/Directory/.htaccess configuration.

This fixed it for my use case.

On my host's servers, use $_SERVER['REDIRECT_REMOTE_USER'] instead of $_SERVER['PHP_AUTH_USER']
