Check if user is logged in

[MatejaSrejic]

Noob here, I'm wondering how can we check if a user is logged in?
I found this section on the docs, but it seems to throw an error.

The error I'm getting is Parse error: syntax error, unexpected ')' in D:\PHP\auth\__\login\index.php on line 8
The code:

<?php
use Kreait\Firebase\Factory;
use Kreait\Firebase\Auth;

require_once('vendor/autoload.php');
$factory = (new Factory)->withServiceAccount('myCredentials.json');
$auth = $factory->createAuth();
$signInResult = $auth->signIn*(); // this is line 8

echo $signInResult->idToken();

$auth->signIn* was just a shorthand for the methods described in https://firebase-php.readthedocs.io/en/5.14.0/authentication.html#custom-authentication-flows , so using this explicitly will not work, but e.g. $auth->signInAnonymously() will

Please note that using one of these methods will sign in the user, so you can't check if a user is signed in with this (because you just signed them in 😅 )

Oh okay thanks for the explanation.
Warned you I'm a newbie 😅

So is there any other way then to check if the user is signed in or not?

Given you have a user ID, you can use it to get a user record, which contains a lastLoginAt field.

$uid = '...';

$userRecord = $auth->getUser($uid);

$lastLoginAt = $user->metadata->lastLoginAt;
