Get Entity's ID in Datastore PHP API - php

Question

Is there a way to get the entity's ID/Key using PHP Datastore API?
I've already authenticated everything and I'm able to get the values, but no the ID
Here's my code:
<?php
$title = "Builder | Makeroid Account";
include "../assets/includes/head.php";
if (!$USER->is_logged_in()) {
$USER->redirect('/');
}
require_once __DIR__.'/../assets/libs/datastore/vendor/autoload.php';
use Google\Cloud\Datastore\DatastoreClient;
use Google\Cloud\Datastore\Query\Query;
$datastore = new DatastoreClient([
'projectId' => 'makeroid-builder'
]);
$query = $datastore->query();
$query->kind('UserData');
$query->filter('emaillower', '=', $U_DATA['email']);
$users = $datastore->runQuery($query);
$params = ["email", "emailFrequency", "emaillower", "isAdmin", "link", "name", "sessionid", "settings", "templatePath", "tosAccepted", "type", "upgradedGCS"];
?>
<div class="content">
<div class="container-fluid">
<div class="row">
<?php foreach ($users as $user) { ?>
<div class="col-md-12">
<div class="card">
<div class="card-header card-header-icon" data-background-color="rose">
<i class="material-icons">assignment</i>
</div>
<div class="card-content">
<h4 class="card-title">User Properties</h4>
<div class="table-responsive">
<table class="table">
<thead class="text-primary">
<th>Key</th>
<th>Value</th>
</thead>
<tbody>
<?php print_r($user); foreach ($params as $param) { ?>
<tr>
<td><?=$param?></td>
<td><?=$user?></td>
</tr>
<?php } ?>
</tbody>
</table>
</div>
</div>
</div>
</div>
<?php } ?>
</div>
</div>
</div>
<?php include "../assets/includes/footer.php"; ?>
I would like to get this:
I'm able to get all values that are in the rows, such us my email, but I hadn't found a way to get that ID
I've tried by using $user['id'], $user['key'] or $user['__key__'] but none of them worked

You'll need to pull the key from the entity (https://googlecloudplatform.github.io/google-cloud-php/#/docs/google-cloud/v0.56.0/datastore/entity?method=key) then pull the id from the key (https://googlecloudplatform.github.io/google-cloud-php/#/docs/google-cloud/v0.56.0/datastore/key) with something like $key->pathEndIdentifier().
So instead of trying to pull the key out of object as a dictionary value, try pulling it out as a method. $user->key()->pathEndIdentifier() .
