How to Access the User, Request, Session & more in Twig via the `app` Variable¶

During each request, Symfony will set a global template variable app in both Twig and PHP template engines by default. The app variable is a AppVariable instance which will give you access to some application specific variables automatically:

app.user: The representation of the current user or null if there is none. The value stored in this variable can be a UserInterface object, any other object which implements a __toString() method or even a regular string.
app.request: The Request object that represents the current request (depending on your application, this can be a sub-request or a regular request, as explained later).
app.session: The Session object that represents the current user's session or null if there is none.
app.environment: The name of the current environment (dev, prod, etc).
app.debug: True if in debug mode. False otherwise.

Twig

<p>Username: {{ app.user.username }}</p>
{% if app.debug %}
    <p>Request method: {{ app.request.method }}</p>
    <p>Application Environment: {{ app.environment }}</p>
{% endif %}

PHP

<p>Username: <?php echo $app->getUser()->getUsername() ?></p>
<?php if ($app->getDebug()): ?>
    <p>Request method: <?php echo $app->getRequest()->getMethod() ?></p>
    <p>Application Environment: <?php echo $app->getEnvironment() ?></p>
<?php endif ?>

Tip

You can add your own global template variables, see How to Inject Variables into all Templates (i.e. global Variables).
