This package enables you to easily log users in via Steam and get user details , using their OpenID service. However, this package does not require that you have the OpenID PHP module installed!

Add this to your composer.json file, in the require object:

"vikas5914/steam-auth": "1.*"

After that, run composer install to install the package.

composer require vikas5914/steam-auth:1.*

require __DIR__ . '/vendor/autoload.php';

$config = array(
    'apikey' => 'xxxxxxxxxxxxxxxxx', // Steam API KEY
    'domainname' => 'http://localhost:3000', // Displayed domain in the login-screen
    'loginpage' => 'http://localhost:3000/index.php', // Returns to last page if not set
    "logoutpage" => "",
    "skipAPI" => false, // true = dont get the data from steam, just return the steamid64
);

$steam = new Vikas5914\SteamAuth($config);

if ($steam->loggedIn()) {
    echo "Hello " . $steam->personaname . "!";
    echo "<a href='" . $steam->logout() . "'>Logout</a>";
} else {
    echo "<a href='" . $steam->loginUrl() . "'>Login</a>";
}

User-Data is accessible through $steam->varName; You can find a basic list of variables in the demo file or a more advanced one in the code.

Check if the user is logged in with $steam->loggedIn(); (Will return true or false)
