<img src="<?php echo $view['assets']->getUrl('images/logo.png', null, true) ?>" alt="Symfony!" />

..versionadded::2.5

Versioned URLs for assets were introduced in Symfony 2.5.

If you need versioned URLs for assets, you can set the fourth argument (or the

``version`` argument) to the desired version:

..configuration-block::

..code-block::html+jinja

<img src="{{ asset('images/logo.png', version=3.0) }}" alt="Symfony!" />

..code-block::html+php

<img src="<?php echo $view['assets']->getUrl('images/logo.png', null, false, '3.0') ?>" alt="Symfony!" />

If you dont give a version or pass ``null``, the default package version will

be used. If you pass ``false``, versioned URL will be deactivated.

..index::

single: Templating; Including stylesheets and JavaScripts

single: Stylesheets; Including stylesheets

second is the version. For instance, ``%s?v=%s`` will be rendered as

``/images/logo.png?v=328rad75``.

..versionadded::2.5

On-demand versioned URLs for assets were introduced in Symfony 2.5.

You can also generate a versioned URL using the fourth argument of the helper:

..code-block::html+php

<img src="<?php echo $view['assets']->getUrl('images/logo.png', null, false, '3.0') ?>">

<!-- renders as:

<img src="/images/logo.png?v=3.0">

-->
