Problem with login via Steam openid (Lightopenid)

[Koji6ac9H]

I started work on the site for the game server, and want to do authorization via Steam, I did everything [URL="http://nikey.me/127/steam-open-id-tutorial-php-video"]tutorial[/URL], but nothing works.

Problem in this line:
$_SESSION['T2SteamAuth'] = $OpenID->validate() ? $OpenID->identity : null;
For some reason I can not get the validation

Code:

    include "api.php"; // My api key
    include "openid.php"; //Official light open id lib.
        $OpenID = new LightOpenID("somesiteplease.p.ht");

    session_start();
 
    if(!$OpenID->mode){
 
        if(isset($_GET['login'])){
            $OpenID->identity = "http://steamcommunity.com/openid";
            header("Location: {$OpenID->authUrl()}");
        }
 
        if(!isset($_SESSION['T2SteamAuth'])){
            echo "<a href=\"?login\"><img src=\"http://cdn.steamcommunity.com/public/images/signinthroughsteam/sits_small.png\" border=\"0\"/></a>";
	}
 
    } elseif($OpenID->mode == "cancel"){
        echo "User has canceled Authenticiation.";
    } else {
 
        if(!isset($_SESSION['T2SteamAuth'])){
 
            $_SESSION['T2SteamAuth'] = $OpenID->validate() ? $OpenID->identity : null;
            $_SESSION['T2SteamID64'] = str_replace("http://steamcommunity.com/openid/id/", "", $_SESSION['T2SteamAuth']);
 
            if($_SESSION['T2SteamAuth'] !== null){
 
                $Steam64 = str_replace("http://steamcommunity.com/openid/id/", "", $_SESSION['T2SteamAuth']);
                $profile = file_get_contents("http://api.steampowered.com/ISteamUser/GetPlayerSummaries/v0002/?key={$api}&steamids={$Steam64}");
                $buffer = fopen("cache/{$Steam64}.json", "w+");
                fwrite($buffer, $profile);
                fclose($buffer);
 
            }
 
            header("Location: index.php");
 
        }
 
    }
 
    if(isset($_SESSION['T2SteamAuth'])){
 
        echo "<div id=\"login\"><a href=\"?logout\">Logout</a></div>";
	$steam = json_decode(file_get_contents("cache/{$_SESSION['T2SteamID64']}.json"));
    	echo "<img src=\"{$steam->response->players[0]->avatarfull}\"/>";

 
    }
 
    if(isset($_GET['logout'])){
 
        unset($_SESSION['T2SteamAuth']);
        unset($_SESSION['T2SteamID64']);
        header("Location: index.php");
 
    } 

P.S. sorry for my english.

Here is what I use for reference:

in the index page of the website:

if(isset($_GET['steam_login']))
{
require ('openid_integration/openid.php');

    try {
        # Change 'localhost' to your domain name.
        $openid = new LightOpenID('domain');
        if(!$openid->mode) {
            if(isset($_GET['st-login'])) {
                $openid->identity = 'http://steamcommunity.com/openid';
                header('Location: ' . $openid->authUrl());
            }

        } elseif($openid->mode == 'cancel') {
            echo 'User has canceled authentication!';
        } else {
            if($openid->validate()) {
                    $id = $openid->identity;
                    // identity is something like: http://steamcommunity.com/openid/id/76561197994761333
                    // we only care about the unique account ID at the end of the URL.
                    $ptn = "/^http:\/\/steamcommunity\.com\/openid\/id\/(7[0-9]{15,25}+)$/";
                    preg_match($ptn, $id, $matches);
                    $steaminfo['64id'] = $matches[1]; //64 bit raw id sent from Steam
                    $authserver = bcsub($steaminfo['64id'], '76561197960265728') & 1; //Converting the 64bit id toa STEAM_0 e.t.c ID.
                    $authid = (bcsub($steaminfo['64id'], '76561197960265728')-$authserver)/2;
                    $steaminfo['steamid'] = "STEAM_0:$authserver:$authid";
            } else {
                    $steamerror = "A problem occured with the Steam sign-in process, please try again.";
            }

        }
    } catch(ErrorException $e) {
        echo $e->getMessage();
    }
}

Then when I need to call a request I just send a form with a get variable. It's pretty standard, just included algorithm to convert 64bit community ID to Steam ID.

Does not work :( openid->validate () returns false
