Getting basic-auth username in php

Question

How can I access the apache basic-auth username in a PHP script?

Answer 1

Simply access this variable:

$_SERVER['PHP_AUTH_USER']

Answer 2

HTTP Auth in the PHP Manual would be a good starting place.

Answer 3

Check what you have in $_SERVER (print_r($_SERVER)), sometimes $_SERVER['PHP_AUTH_USER'] is not available.

If you have value for $_SERVER["HTTP_AUTHORIZATION"], you may use:

if (isset($_SERVER["HTTP_AUTHORIZATION"]) {
        $auth = $_SERVER["HTTP_AUTHORIZATION"];
        $auth_array = explode(" ", $auth);
        $un_pw = explode(":", base64_decode($auth_array[1]));
        $un = $un_pw[0];
        $pw = $un_pw[1];
    }
