.. note::

The ``template_from_string`` function is not available by default. You
must add the ``\Twig\Extension\StringLoaderExtension`` extension explicitly when
creating your Twig environment::
The ``template_from_string`` function is not available by default.

In Symfony projects, you need to load it in your ``services.yaml``::

services:
Twig\Extension\StringLoaderExtension:

or ``services.php``::

$services->set(\Twig\Extension\StringLoaderExtension::class);

Otherwise, add the extension explicitly on the Twig environment::

$twig = new \Twig\Environment(...);
$twig->addExtension(new \Twig\Extension\StringLoaderExtension());
