# `sort` The `sort` filter sorts an array: <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1 2 3</pre></div></td><td class="code"><div class="highlight"><pre>{% for user in users|sort %} ... {% endfor %} </pre></div></td></tr></table> Note Internally, Twig uses the PHP [asort](http://php.net/asort) [http://php.net/asort] function to maintain indexassociation. It supports Traversable objects by transformingthose to arrays.
