Use PHP function in TWIG?

Question

In PHP templates I can use php functions, for example:

foreach ($users as $user){
  echo someFunction($user->getName());
}

How can I make it in TWIG?

{% for user in users %}
    * {{ user.name }}
{% else %}
    No user have been found.
{% endfor %}

How do I achieve this?

What you need are functions or filters. You can easily add these using the examples.
